This investigation was carried out at El-Serw Agricultural Research Station, Damietta Governorate and Mansura unit Research during 2005 and 2006 seasons to study the purpose was to the effect of irrigation intervals i.e 14, 21 and 28 days and potassium fertilizer rates i.e 0, 24 and 48 Kg K2O/feddan on yield and seed quality of five grain sorghum cultivars, i.e. Dorado, Giza 113, Giza 15, Shandawheel - 2 and Shandawheel - 6. The experiment was laid out in a split plot design with three replicates. Results showed that prolonging irrigation intervals decreased number of days to 50% heading, panicle weight, panicle grain weight, seed index, grain yield/ feddan and seed quality traits, as well as germination percentage and rate, plumule length, radical length, seedling dry weight, accelerated aging and electrical conductivity of the produced grains in both seasons. Irrigation at 28 days interval caused 30.91% and 30.41% reduction in grain yield per feddan in 2005 and 2006 seasons, respectively, compared with that of 14 days interval. Increasing potassium fertilizer rate up to 48 Kg K2O/feddan increased all studied traits. Applying potassium at the rate of 48 Kg K2O/feddan gave 15.31% and 15.32% increase in grain yield/ feddan compared with unfertilized plants in 2005 and 2006 seasons, respectively. Grain sorghum cultivars differed in grain yield and all studied traits in both seasons. Hybrid Shandawheel 6 was superior in grain yield per feddan compared to other tested varieties in both seasons. The interaction effects were significant on almost studied traits in both seasons. Generally, it could be concluded that sowing hybrid Shandawheel- 6 and fertilized with 48 Kg K2O /feddan plays a prominent role in increasing grain yield/ feddan and quality of produced seeds under irrigation water shortage (14 days interval) in North delta of Egypt.

Two field trials were conducted at the Agric. Exp. Sta., Fac. Agric., CairoUniversity, in 2003/2004 and 2004/2005 growing seasons. The objective was studying the response of two faba bean cultivars (Giza 843 and Cairo 375) to three plant densities (22, 33 and 44 plants/m²) under three sowing dates (October 15th, November 5th and November, 25th) .The most important results could be summarized as follows:
Seed yield /faddan, seeds/plant, number of pods and harvest index of 5 November sowing were significantly higher than those of 15 October or 25 November sowing dates. However, branches/plant (no.), plant dry weight and biological yields of early sowing (15 October), were significantly the highest.
Yields of faba bean/fad and harvest index had significantly increased with increasing plant density to 44 plants /m², but the other individual plant characters tended to decrease with the increase of plant density.
Cairo 375 cultivar significantly surpassed Giza 843 in seed and biological yields /faddan, harvest index and number of pods and seeds/plant but the former had lighter seed index and plant dry weight than the later.
Significant varietals responses to sowing date and plant density had detected.The maximum seed yield (2 ton / fad.) could achieve by sowing Cairo 375 cultivar on 5 November with a plant density of 44 plants /m².

IMPROVING BIOACTIVITIES OF SOME BACTERIAL BIOCONTROL AGENTS AGAINST CHICKPEA ROOT ROT AND WILT CAUSAL ORGANISMS USING SKIMMED MILK.
G.
Amer
Biocontrol activities of Pseudomonas spp. are widely accepted as biocontrol agents for many diseases. The main target of this research work was to find out a proper and effective formula for the bio-agents which enhance, survivability, rhizosphere competence and biological control of chickpea root rot and wilt. The results obtained revealed that the use of skimmed milk and whey as nutrients and protecants improved the survivability of Pseudomonas fluorescens and P. putida up to 180 days without any dramatic decline when stored at room temperature (25 + 5 0C). The formulation enhanced the rhizosphere competence of P.fluorescens and P. putida which increased the population in the rhizosphere of chickpea up to 75 days from sowing. The formulated isolates were used as seed coating or soil treatment or combined seed and soil treatments for biocontrol of fusarial wilt and rhizoctonia root rot of chickpea. Results showed a significant reduction of the percentages of infected plants . Seed treatment followed by soil application gave the lowest percentages of infection compared to the control. The saprophytic growth of Fusarium oxysporum f. sp < em>. ciceri and Rhizoctonia solani in the experimental soil was significantly reduced after the application of powder formulation of the biocontrol agents.

Utilization of fluorescent pseudomonads bacteria (FPB) as plant growth promoting agents offers a promising alternative solution to the application of potential harmful agrochemicals. In this study, FPB inhabiting ectorhizosphere and endorhizosphere of different cultivated and wild plants species were enumerated. Rhizospheres of wild plants, in general, were found to harbor high FPB population density compared to rhizospheres of cultivated plants. From counting plates, ninety five FPB isolates representing different morphological types were obtained. The isolates were in vitro screened for activities related to plant nutrition and plant growth regulation, for antifungal traits and for antagonistic potential towards different phytopathogenic fungi. Results showed that varied proportions of the FPB isolates are putative nitrogen fixers, solubilize phosphate and zinc, produce indoleacetic acid, produce varies antifungal traits and inhibit phytopathogenic fungi. Based on the results of screening, isolates were assessed for their ability to function as plant growth promoting rhizobacteria (PGPR) and ranked. Among the top 20 FPB isolates, 8 were isolated from rhizosphere of Rotrait (Zygophyllum coccineum), 6 from Kokia (Spergularia marina L.), 3 from Akol (Alhagi graecorum, boiss), and 3 from Maize (Zea mays L.) plant.

ENZYMATIC ACTIVITIES OF FUNGI ISOLATED FROM LETTUCE LEAVES
Hoda
Al-Homeidan
Six fungal species, namely: Alternaria alternata, Botrytis cinerea, Fusarium rousm, F. tricnictum, Stemphylium botryosum and Thielaviopsis sp. were isolated from lettuce leaves collected from Riyadh markets during summer months in 2005. The fungal isolates were examined for their ability to produce five extracellular enzymes, namely: amylase, lipase, protease, cellulose and phenoloxidase, on solid media. They were also examined for production of one endoenzyme which is phosphatase. The results showed that all isolates were able to produce amylase though with variable magnitudes; the highest amylase activity was displayed by F.rousm followed by F. tricnictum. Concerning lipase activity Theilaviopsis sp. and F. rousm showed the highest potential; A. alternate and F. tricnictum came next, whereas B. cinerea and S. botryosum failed to produce lipase.Regarding protease enzyme, only two isolates (A. alternata and F. rousm) were able to produce the enzyme. The present study showed also that A. alternata followed by B. cineria, F. rousm and S. botryousm were able to produce cellulase, whereas the other two fugal species did not display any cellulase activity. On the other hand, all isolates, except B. cinerea do not produce phenoloxidase. Meanwhile, the largest colonial diameter on agar media was yielded by F .rousm followed by S. botryosum A. alternata, F. tricnictum, and B. cinerea, respectively. This investigation also showed that the cell-free extracts of all the fungal isolates tested appeared to catalyze the phosphate ( adenosine 5-monophosphate, AMP) hydrolysis; and the following sequence was displayed for acid phosphatase activity of the experimental fungal isolates: A. alterna, B. cinerea , S. botryousm, Theilaviopsis sp., F. tricnictum andF. rousm, in descending order, respectively.

In this investigation 11 inbred lines of maize were used. These inbred lines were crossed among them to obtain 30 F1 hybrids according to factorial mating design. DNA finger printing was made by using RAPD-PCR for all 11 maize inbred lines. The two primers, XD8 and XD9 were used in this technique. The results showed similarity between inbred lines. The results also revealed the presence of three common bands between all inbred lines at primer XD8, while five common bands were obtained at primer XD9. Cluster analysis for similarity degree between the 11 parental inbred lines was done and showed similarity degree between the within inbred lines. Phylsgenetic analysis showed high similarity coefficient between the inbred lines 6, 4 and 2, 3. However, there were high genetic distances obtained between inbred lines No: 4, 5, 6, 7 and 11.

Macromorphological characters of roots, stems, leaves, fruits and seeds, in addition to the micromorphological features of seed surface sculptures performance by Scanning Electron Microscope (SEM), as well as electrophoretic identification of 4 species belongs to 3 genera of the family Chenopodiaceae (Goosefoot) were studied. These species were; Chenopodium quinoa Willd (Quinoa), Spinacia oleracea L. (Spinach), Beta vulgaris var. cicle L. (Chard) and Beta vulgaris L. (Beet).
Because the species Chenopodium quinoa introduced and cultivated quite recently in Egypt and considered a new additive product to wheat cereal to produce a good bread quality,a new high protein crop (50 % more than wheat), so it is a pseudocereal rather than a true cereal. The objective of this study was raised up to distinguish between this species and some of the more popular species of the same family using some micro and macromorphologyical characters. In addition, electrophoretic identification of the investigated species was under consideration.
The brief results obtained from the macromorphologyical studies on roots, stems, leaves, fruits and seeds indicated that the species Chenopodium quinoa has characters varied compared with the other species. The macromorphologyical results on seed surface indicated that the species Chenopodium quinoa has falsifoveate seed surface pattern, while these patterns were; reticulate - rugose in Spinacia oleracea; reticulate - areolate in Beta vulgaris var. cicle and scalariform in Beta vulgaris. Data on biochemical analysis indicated that polyacrylamide gel electrophoresis separation of total soluble proteins can be used as a genetic finger print for identification, differentiation and comparison among the four studied species of the family Chenopodiaceae.

Twenty isolates belonging to nine Fusarium spp. were tested for levels of pathogenicity on two cotton cultivars under greenhouse conditions. Preemergence damping-off, postemergence damping-off, survival and dry weight were used as criteria to evaluate pathogenicity of the isolates. Proteins and alcohol dehydrogenase (AD) isozymes of the isolates were separated by SDS-PAGE, and PAGE, respectively. Virulence patterns, protein banding patterns, and AD isozymic patterns patterns were used to differentiate among Fusarium isolates belonging to the same species. In the three methods, cluster analysis was used to differentiate among the isolates, which showed low similarity levels-that is, the isolates, which belonged to remotely related or unrelated subclusters. On the other hand, cluster analysis was not a reliable method to differentiate among the isolates belonging to closely related subclusters because such isolates had relatively high similarity levels. The results of the present study suggest that isolates belonging to the same Fusarium species could be differentiated by their differential pathogenicity, combined with their specific protein and AD banding patterns separated by electrophoresis.

The present study was carried out during 2006 and 2007 seasons to evaluate the effect of dipping persimmon fruits in different concentrations of ethephon and ethanol solutions as post harvest treatment to remove astringency and hasten fruit ripening.
The data indicated that ethephon at 750 ppm was superior effect for reducing fruit firmness and total tannins with increasing total soluble solids and enhancing ripening process than dipping fruits in 500 or 1000 ppm. Moreover, ethanol application at 25 % was suitable to accelerate fruit ripening with increasing soluble solids than dipping fruits in 50 % concentration. Since, these treatments were more effective to remove fruit astringency through reducing tannin content. Also, these solutions are save for human health.

This study was carried out during the seasons of 2006 and 2007 to present the suitable date of grafting for Zebda, Fagriklan, Seedek, Ewais and Keitt mango cultivars onto Zebda rootstock in order to obtain a higher successful grafts of mango cultivars.
Grafting mango cultivars with the cleft method especially on April produced a higher percent of successful grafts and gave highest scion growth with longer, thicker shoot and more number of leaves on the seedling than those taken in September. Furthermore, grafting both Zebda and Fagriklan on Zebda rootstock gave higher values of successful grafts and growth of the transplant than those obtained from grafting Seedek, Ewais and Keitt on the same rootstock. Whereas, Ewais and Keitt cultivars gave less vigorous grafts than that obtained from the other cultivars in the two dates of grafting.

An investigation on Lycopersicon esculentus cvs. Castle Rock (CR), Strain B and Super-Marmand (Tomato) was conducted to standardize the method of high frequency regeneration. Cotyledon and hypocotyl from 12 days old seedlings were used. Comparison was made on cotyledon and hypocotyl explants cultivated on 4 different regeneration media of three cultivars. The best results for shoot primordial numbers per explants were observed of hypo-cotyledon explants with MS medium containing 1mg/L BA of cultivars Castle Rock and Super-Marmand, was reached (91-87% respectively), while the best results for shoot primordial numbers per explants reached the highest value (83%) for strain B by using MS medium supplemented with 0.5 mg/L BA compared to the other treatments. While, the best results for shoot primordial numbers per explants were observed of cotyledon explants with MS media containing 2.0 mg/L BA of cultivars Castle Rock, strain B and Super-Marmand compared to the other treatments, was reached (79,72 and 80%, respectively). The percentage of shoots forming roots was reached the highest value 95 and 90 % of Castle Rock (CR) and Super-Marmand, respectively by using MS medium supplemented with 1.0 mg/ L IBA, while the best results of shoots forming roots was reached the highest value (92%) for strain B by using MS medium supplemented with 0.5 mg/L IBA and 0.5 mg/L NAA. Tomato plants are able to regenerate within 2 months and the young plantlets can be transferred to pots for hardening. Hardening procedure for tissue culture raised plantlets was standardized using sterile mixture of sand and soil in plastic pots.

A two field experiments were carried out in a special farm at "Mitt Sharaf" Dekerniss distract, Dakahlia Governorate, Egypt during the two successive wintery seasons of 2003-2004 and 2004-2005 to study the effect of foliar spray with a biological promoters, fertilization with different nitrogen sources, with or without inoculation with biofertilizers and their interactions on growth, chemical contents and yield, as well as, yield components of pea plants (Pisum sativum L.) cv. Master-B.
The split-split plot system in a randomized complete block design with three replicates was used in both growing seasons. The chemical and organic fertilizers (farmyard manure, chicken manure and compost) were randomly located in the main plots, whereas, the sub-plots were devoted for the foliar treatments (yeast extract and biomagic). The biofertilizer treatments (with and without inoculation with Rhizobium + Mycorrhiza) were assigned to the sub-sub plot.
By comparing the N-sources (as a single factors), the best treatment is the control followed by chicken manure followed by F.Y.M and the compost came in the last. By comparing the foliar application treatments, there is no significant difference between the yeast extract and the biomagic, whereas, these two treatments (each of them) is better than without. As well as the inoculation with biofertilizer (Rhizobium + Mycorrhiza) is better than without.
The higher values of total green pod and dry seed were obtained from plants which received the chicken manure fertilizer, sprayed with yeast extract or biomagic and inoculated with biofertilizer comparing with other organic fertilizers sources. This treatment gave a total green and dry seed yield values more than that has the chemical fertilizer (control).
By conducting on economical estimation, it appears that the treatment of the triple interaction (chicken manure + yeast extract + biofertilizer) gave 2.19 fold as a net return comparing with control.

Roses (Rosa hybrida, cv. Eiffel Tower) grafted onto R. canina were lifted on 1st Feb. 2006 and 2007. The bare – rooted one year old roses were treated with hot paraffin wax or polyethylene emulsion, packaged with polyethylene pags and later with cardbord poxes and placed in cold storage at 0˚C, RH95%. After 4, 8, 12 or 16 weeks in cold storage the bare – rooted roses were planted in pots containing clay +sand 2:1 under saran house. Plants were tested for water loss, survival plants, and numbers of buds, number of flowers and stem length. Also carbohydrates concentration were measured in rose plants in the different storage periods. Paraffin wax treated plants lost the minimum amount of water than polyethylene emulsion and control plants in all cold storage periods respectively. Also, 100% of paraffin wax treated plants developed till flowering in all cold storage periods, while 45.8% of polyethylene emulsion treated plans and 58.9% of control plants were developed only during the two seasons. The biggest number of buds, and flowers and stem length were significantly recorded in paraffin wax treated plants than control and polyethylene emulsion treated plants respectively.
There were slight differences between all treatments concerning carbohydrates concentrations as well as in different storage periods.

Anther at the mid uninucleate stage of pollen development were obtained from two apple genotypes cultivars and stored for one week in refrigerator at 4 ºC. Anther was cultured on MS medium supplemented with 5% sucrose and combination of phytohormones [6-Benzylaminopurine (BA), thidiazuron (TDZ), indol-3-butyric acid (IBA), Naphthalene acetic acid (NAA)] for callus induction and regeneration. Addition of TDZ+IBA to multiplication medium were more effective for increasing the number of initiated shoots compared with BA, NAA. The average percentage of callus formation from Dorsett golden cultivar 31.64% in the first season, while it was 28.38% in the second season. Anna revealed a 27.86% & 25.99% of callus formation in the first &second season, respectively. Regeneration percentage was 24.86%& 23.82% with Dorsett golden, however, it was 20.57% &19.79% with Anna in the first and second seasons, respectively. Positive correlation between media and genotype was showed in first season only for plant regeneration. Moreover, a negative correlation was revealed between media and genotype for callus induction in both seasons. Cytological studies revealed normal cells ranged from 96.90%-97.85% and abnormal cells of about 2.15%-3.01%.
