Two pot experiments were carried out during the two winter seasons of 2013/2014 and 2014/2015 under greenhouse conditions at the Department of Agricultural Botany, Faculty of Agriculture, Kafrelsheikh University, Egypt to investigate the influence of salicylic acid (1 mM) and abscisic acid (0.1 mM) on morpho-physiological characters and anatomical structure as well as yield characters of faba bean plants under drought stress. As a result of stress only, all studied morphological and anatomical characters as well as chlorophyll concentrations and yield components were decreased, whereas, electrolyte leakage was increased under drought stress. However, application of salicylic acid (SA) and abscisic acid (ABA) under drought stress significantly improved or increased all the mentioned characters except electrolyte leakage which was decreased. Application of SA and ABA under drought stress enhanced the anatomical characters of faba bean stem and leaflets, for instance, stem diameter, number of vessels/bundle in stem as well as leaf lamina thickness and average diameter of xylem vessel. Accordingly, the exogenous application of SA and ABA lead to minimize the harmful effect of drought stress and improve the morpho-physiological characters, stem and leaflets anatomy as well as yield components of faba bean plants even under drought stress.

This investigation was undertaken to study the effects of different soil application of some biostimulants fertilizers on some vegetative growth, fruiting parameters and fruit quality as well as leaf nutrient content of "Anna" apple trees budded on MM106 rootstock grown under El-Kanater Horticultural Research Station conditions during 2013 and 2014 consecutive seasons.
The obtained data displayed obviously that all treatments in this study resulted in a positive increase in all investigated vegetative growth measurements i.e., shoot length, number of leaves/shoot, leaf dry weight and leaf area. Furthermore, fruiting parameters (fruit set %, tree yield in kg and yield increment (%) in relation to the control) were increased when trees treated with all studied treatments in the two experimental seasons. Moreover, fruit quality including both fruit physical characteristics i.e., fruit weight, volume, firmness, height, diameter and fruit shape index and fruit chemical properties such as TSS %, acidity % and TSS/acid ratio were improved by subjected trees to different biostimulants treatments as compared with the control. In addition to that, leaf nutrient contents of some macro-elements (N, P and K) and some micro-nutrients (Fe, Zn and Mn) were improved from the standpoint of statistic by all investigated treatments as compared the control during both 2013 and 2014 seasons of study.
In general, it could be concluded that, all investigated biostimulants treatments under study exhibited a significant and beneficial influences on most of parameters and characters of "Anna" apple fruit trees. However, the Humic acid treatment was the most effective for increasing both vegetative growth and fruiting parameters as well as improving majority of fruit quality and leaf nutrient contents of "Anna" apple trees.

Four annual herbaceous species of Solanaceae were subjected to a comparative anatomical study on their stems at different growth successive stages. The main obtained results could be summarized as follows : 1- The extent of persistence of the epidermis during secondary growth of the stem differed according to the studied species. It may persist until the end of vegetative growth or may be substituted by a periderm initiated within timing of the periderm formation and extent of its development differed in the investigated species. 2- The clear manifestation dilatation growth in the extraxylary tissues of the stem differed according to species, depending probably on the rate of this process. 3- Pith diameter in the stem may remain unchanged after secondary growth, or it may largely decreased, according to species.

Two annual herbaceous species of Solanaceae namely, Datura stramonium L. and Capsicum frutescens L. were subjected to study the incidence of the secondary growth and consequents the formation of protective tissues in their roots. The main results were as follows :
1- At an early stage of growth, the xylem tissue at the base of the root accomplished a proportion of its final amount that was decidedly bigger than that needed for the shoot system already achieved by the plant. It appeared therefore that certain amount of water conducting elements should be developed prior to the successful start and continuation active vegetative growth.
2- The amount of secondary growth varied in roots of the two investigated species; it was clear that the bigger the amount the more readiness of the root to form a periderm-like structure until a true periderm was developed with the biggest amount.
3- The periderm-like structure appeared in the exodermis or the underlying cortical layers according to the species, while the true periderm developed normally in the pericycle.
4- The endodermis and pericycle may behave alike or unlike as to their response to secondary growth.

Two field experiments were carried out at the Farm of Environmental Studies and Research Institute, Sadat City University, during both seasons of 2013 and 2014to determine the effect of deficit of irrigation on vegetative growth characteristics, yield and its components and tubers quality on two potato cultivars Solanum tuberosum L.) cvs. Red Sun and Sophie) under sandy soil conditions. In this study, the experiment included 8 treatments, which were the combination between four levels of irrigations i.e., 100% (734.63 and 698.82 mm/fed.), 80% (587.7 and 559.1 mm/fed), 65% (477.6 and 454.23 mm/fed.) and 50% (367.32 and 349.41 mm/fed.) and two cultivars of potato (Red Sun, and Sophie) during both seasons 2013 and 2014 respectively. The results showed that, plant height, number of branches and fresh weight/plant, average tuber weight and tuber weight plant as well as tubers yield per feddan were significantly increased by using the highest level of irrigation ,while marketable yield % was not significantly affected and the size of tubers also was affected by irrigation levels . In addition, cv. Red Sun showed significant increasing in the vegetative growth expressed as plant height, fresh weight/plant, yield and its components and its quality compared with cv. Sophie. On the other hand cv. Sophie reflected significant increase in number of branches than cv. Red Sun. In this regard, marketable yield % was not significantly affected result of tested cultivars .The results showed that, the interaction between the cv. Red Sun and the highest level of irrigation resulted in significant increases in plant height, fresh weight/plant, average tuber weight and tuber weight per plant as well as tubers yield per feddan, marketable yield % and large tuber than size more than 70 mm in diameter also results indicated that cv. Sophie with the highest level of irrigation significantly increased number of branches / plant than cv. Red Sun.

Foliar sprays with synthetic biostimulants or microbial biostimulants PGPR (plant growth promoting rhizobacteria) were used . They contain amino acids, macro and micro elements, humic acid and vitamins . Also its direct effect in release stimulants, nutrients, antibiotics, biosides and sidrofores or activation of these microorganisms in plant rhizosphere in activation and improving plant growth. This study was carried out during 2013 and 2014 seasons on 10 years old Washington navel orange (Citrus sinensis Osbeck) trees budded on sour orange (Citrus aurantium L.) rootstock, grown in a private orchard located at Motobus, Kafr El Sheikh Governorate, to study the effect of synthetic stimulants (Furdose) and microbial biostimulant (Azospirillum lipoferum )on fruit set, dropping, yield and fruit quality. Furdose as a commercial synthetic biostimulant and microbial biostimulant Azospirillum lipoferum were used as foliar application alone or in combination at two stages, before flowering(first mach) or after fruit set(first may) or before flowering and after fruit set. The obtained results revealed that, fruit set and drop percentages, yield and fruit quality were u significantly affected by Furdose and Azospirillum lipoferum treatments alone or in combination in both seasons . The data cleared that, both stimulators enhanced fruit set percentage, yield and fruit quality of Washington navel orange trees . Azospirillum lipoferum alone or combined with Furdose was more effective on improving the productivity and fruit quality .The T6 (foliar spray of A. lipoferum after fruit set), T7 ((foliar spray of A. lipoferum before flowering and after fruit set) and T10 (foliar spray of Furdose plus A. lipoferum before flowering and after fruit set) were the most effective treatments on yield and fruit quality. It increased fruit set, yield and fruit quality in terms of fruit number, fruit kg/tree, fruit firmness, soluble solids content, reducing and total sugars and vitamin C. Fruit drop was decreased without significant differences among them in both seasons. Thus spraying with Azospirillum lipoferum after fruit set T6 ( foliar spray of A. lipoferum after fruit set) ) gave 112.4 and 115.7 kg/tree compared with T7 (foliar spray with Azospirillum lipoferum before flowering and after fruit set) 108.7 and 121.4 kg/tree and T10 ((foliar spray the combination of them before flowering and after fruit set) 114.7 and 130.3 kg/tree during both seasons, respectively . The use of ( Azospirillum lipoferum ) is recommended for increasing fruit yield and quality such as firmness, SSC, V.C and total sugars which may be increase the fruit ability to handling stages and longest shelf life, and gave the highest of net return per feddan and the increase in net return over control. when used alone or with synthetic biostemulants ( Furdose) compared with the use of synthetic biostemulants ( Furdose) alone .

This study was conducted with the objective of estimating combining ability and gene action for both of seed and straw yields as with as their components in six flax genotypes. This was achieved via evaluating six parents (P1= Giza 8, P2= Sakha 2, P3= S.413/1/2/3, P4= S.420/12, P5= Cizar and P6 = Bombay) with their 15 F2,s progenies. In 2014/2015 season, the six parents and their 15 F2,s crosses were planted in a randomized complete block design with three replications at Giza Res. Station Farm.
The collected data indicated that the additive effects were more important than non-additive effects for each of straw yield, plant height, technical stem length, seed yield, no. of capsules per plant, 1000-seed weight and no. of seeds per capsule indicating that effective selection should be possible within these F2 and subsequent generations for these characters. While, both additive and non-additive effects were the same almost effect in inheritance of no. of basal branches per plant.
P3 and P4 showed high general combining ability for each of straw yield per plant, plant height and technical stem length. Also, P1 proved to be good combiner for seed yield and its two important components, no. of capsules per plant and 1000-seed weight in addition P5 exhibited high general combiner for all seed yield characters except 1000-seed weight, suggesting the importance of these parents for increasing the previous traits in flax breeding programs. The simple correlation between GCA values and parental means for all characters studied were significantly positive. These results indicated that the parents showing higher mean performance proved to be the highest general combiners for these traits. One cross (P3xP5) exhibited significant and positive SCA effect for each of straw yield, plant height and technical stem length as well as this cross included high x low general combiners parents for GCA effects for straw yield. For seed yield, one cross (P1xP5) showed significant positive SCA values for both seed yield and no. of capsules per plant as well as this cross involved high x high general combiner for these two traits in addition one cross (P1xP2) had high x high general combiner parents for 1000-seed weight. Therefore, these crosses (P3xP5, P1xP5 and P1xP2) may prove useful for simultaneous improvement of the above-mentioned traits.
Straw yield per plant was significantly positively correlated with both of plant height and technical stem length. Also, plant height exhibited high positive correlation with technical stem length. On the other hand, seed yield per plant exhibited highly significant and positive correlation with each of no. of capsules, 1000-seed weight and no. of basal branches. Therefore, the possibility of using the two traits (plant height and technical stem length) as selection indices for improving straw yield per plant as well as, using 1000-seed weight and capsules number per plant as selection indices for improving seed yield per plant.

The present study provides quantitative assessment of the hydrosoil and overlying water characteristics in addition to vegetation analysis of five aquatic habitats and their wet shorelines dominated by Ceratophyllum demersum, Myriophyllum spicatum, Potamogton crispus, P. nodosus and P. pectinatus. Experimental study was conducted to evaluate rate of release of heavy metals from living and dead hydrophytes to the surrounding water. The bottom sediments and overlying water were different markedly in the five habitats. The sediments samples were sandy textured with predominance of fine sanarticles size=0.211 – 0.104 mm), whereas sites and clay fractions constitute small proportion. Organic carbon, total soluble salts, anions and cations were generally higher in summer months. The floristic components of the five communities comprised 51 species related to 27 families. Poaceae, Asteraceae, Cyeprceae, and Potomogetonaceae were the major families contributing 45% of the recorded species. Therophytes were the common life – froms. Rate of heavy metals release from living plant samples was higher than that from the dead samples.

The main aim of this study is to determine the suitable level of solid organic wastes (SOW) as natural fertilizers to increase productivity and to avoid heavy metal burden in the soil and monitoring the changes in physical and chemical characters of soil due to utilization of solid organic wastes. The present study, the application of solid organic wastes has improved the physical properties of soil such as increasing the fine particles, porosity and water holding capacity. Also the chemical properties increased such as organic carbon, electric conductivity and total soluble salts. The solid organic wastes (SOWs) exhibit several benefits such as: improving of physical and chemical characters of soil, increasing productivity of Sorghum virgatum plants. On the other hand, SOWs have some harmful effects on: soil environment such as increasing the soil pH. Consequently, further future ecological studies should bring the view to the ideal utilization of these wastes without side effect on the environment
