The effect of the previously mentioned factor on yield, yield components, oil yield and some water relations were studied.
Results indicated that number of capsules/ plant, length of fruiting zoon (cm), seed weight /plant (g), 1000-seed weight (g), seed yield (kg/ fed), and oil yield (kg/ fed) were significantly affected by the irrigation treatments. The highest values were obtained for I<sub>3</sub> treatment except length of fruiting zoon (cm) which was increased for I<sub>4</sub> treatment. Shandaweel3(V<sub>3</sub>) was superior in seed yield in 2005 season by 34.90, 7.90 and 10.30 % as compared with V<sub>1</sub>, V<sub>2</sub> and V<sub>4</sub>, respectively. However, in 2006 the respective increase in seed yield reached about 54.30, 5.60 and 5.90 %. The best interaction effect was found for I<sub>3</sub> with V<sub>3</sub>. Giza32 variety was superior in oleic acid and Sohag1 variety gave the maximum value in omega-6 as compared with the other varieties.
Water consumptive use or evapotranspiration (ETcrop) in 2005 season was 2528, 2440, 2466 and 2932 m<sup>3</sup>/ fed for I<sub>1</sub>, I<sub>2, </sub>I<sub>3</sub> and I<sub>4</sub> treatments, respectively. The respective values in 2006 were 2639, 2549, 2565 and 3052 m<sup>3</sup>/ fed. The highest ETcrop was found for I<sub>4</sub> in both seasons, while, I<sub>2</sub> treatment showed the minimum value.
With respect to varieties, values of ETcrop in 2005 were 2795, 2479, 2524 and 2569 m<sup>3</sup>/ fed, for V<sub>1</sub>, V<sub>2</sub>, V<sub>3</sub> and V<sub>4</sub>, respectively. However, in 2006, the respective values were 2893, 2591, 2637 and 2684 m<sup>3</sup>/ fed. The variety of V<sub>1</sub> registered the highest ETcrop in both seasons, however, V<sub>2</sub> variety gave the lowest one followed by V<sub>3</sub>. The variety V<sub>2</sub> saved irrigation water about 11.3, 1.9 and 3.5 % in 2005 and 10.4, 1.7 and 3.5 % in 2006 as compared with V<sub>1</sub>, V<sub>3</sub> and V<sub>4</sub>, respectively. The interaction between I<sub>4</sub> with V<sub>1</sub> gave the highest ETcrop, however, the lowest ETcrop was found for the interaction of I<sub>2</sub> with V<sub>2</sub> in both seasons.
Crop water productivity (CWP) was increased for I<sub>3</sub> treatment compared with the other irrigation treatments under study. At the same time, V<sub>3</sub> gave the highest CWP, while, V<sub>1</sub> gave the lowest one in both studied seasons. The interaction between I<sub>4</sub> with any variety registered minimum values of CWP. While, I<sub>3</sub> with any variety gave maximum ones. The best interaction was found for I<sub>3</sub> with V<sub>3</sub>.
It can be concluded that subjecting sesame plants to long interval days between irrigations at capsule development stage encourage the plants to give more number of capsules, increase in seed weight/ plant and increase in seed yield/ fed accordingly. Shandaweel3 (V<sub>3</sub>) is more tolerant to water deficit as compared with the other varieties under study, while, Giza32is the most vulnerable. Also, flowering stage is more sensitive stage to water deficit, while, capsule development stage is more tolerant in the life of sesame plants.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691720100701EFFECT OF TIME BEFORE LIFTING IRRIGATION OF FRIGO STRAWBERRY TRANSPLANTS ON THEIR QUALITY AND PRODUCTIVITY8738788654910.21608/jpp.2010.86549ENIslah M.El-HifnyPlant Production Dept., Desert Res.

Each genotype was planted in four rows, five meter long and 20 cm a part with three replications, where two the outer rows were used as borders and the two inner rows were used to record the data. The best selected genotypes, under both drought and heat conditions, according to their desirable traits, were evaluated under the same conditions during 2008 and 2009 rice growing seasons. These experiments included 18 and 20 out of 100 rice genotypes under drought and heat conditions, respectively.
The results indicated that, the vegetative characters comprising of days to heading, plant height, tillers number/plant and leaf area. Also, root characters, comprising root length, root volume, root to shoot ratio and roots number/plant, could be considered as parameters related to tolerance. These traits could be used as selection criteria since they helped the plant to maintain a favorable water balance and, hence, controlled, early stomata closure. Analysis of variance showed significant variations among the vegetative and root characters under drought conditions. Heritability estimates were higher for grain yield (0.92), plant height (0.88), leaf area (0.82), number of grains per panicle, root/shoot ratio (0.81) and days to heading (0.88). Consequently, selection for grain yield and its components could be more effective in the selected genotypes under drought and heat conditions. <strong><span style="text-decoration: underline;"> </span></strong>Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691720100701EFFECT OF AUXINS AND ASCORBIC ACID ON PROPGATION OF Bougainvillea glabra THROUGH STEM CUTTINGS8939018655110.21608/jpp.2010.86551ENH.

Box 34517 (54), Egypt.Journal Article20200502A survey was made to study the pattern of <em>Plantago major</em> distribution; floristic composition; role of its habitats characteristics on phenotypic plasticity at Damietta, Egypt. Twenty stands were selected to cover seven habitat types. These habitats were namely: sandy fertile cultivated lands, irrigation canals, orchards, reclaimed lands, waste lands, public gardens, and road sides.<em> Plantago major</em> was found to be associated with 24 species (14 annuals and 10 perennials) belonging to 23 genera and related to 11 families. The majority of the recorded species are therophytes (65%). The geophyte life form was the most distributed, it occupied 17 sites of the study area. <em>Plantago major</em> had a wide ecological amplitude, it was recorded in soils with wide range of moisture content (5.54:37%); salinity (153.2:549.05 μmhos/cm) and nutrients e.g sulphates (0.106:0.584%); calcium carbonates (4.4:20.5%); Ca<sup>++</sup>(3.6:11.2 mg/g dry wt) and phosphorus (3.65:23.5 mg/g dry wt). This high amplitude forced <em>Plantago major </em>to show a considerable morphological plasticity; variation in biomass and water content. There was a correlation among studied traits, indicating a high degree of phenotypic characters. The major soil variables affect the phenotypic plasticity of <em>Plantago major</em> were moisture content, soil salinity, sulphates, calcium carbonates, Ca<sup>++</sup>, and phosphorus.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691720100701INFELUNCE OF PLANTING DATE AND MEDIA ON ROOTING OF STEM CUTTING OF Bougainvillea glabra103310408656110.21608/jpp.2010.86561ENH.

The results clearly show that, the rooting medium peat moss gave the best significant results in rooting percentage (100%) in both season with cuttings cultured in mid December in both season. Concerning, number and length of root/plant, different planting dates didn't record significant values with the media examined. While peat moss medium recoded the highest significant values comparing with other media in number of root/plant (16.3 and 13.3 ) during 1<sup>st</sup> season and (11.3 and 11.0) during 2<sup>nd</sup> season in February and December ,respectively. in root length cm/ plant (10.5 and 12.33.) during 1<sup>st</sup> season and (10.6 and 10.3 ) during 2<sup>nd</sup> season in February and December respectively. Regarding, shoot length cm/plant, the cuttings planting during December recorded the best results, values that were (30.3 and 31.0 cm/plant) comparing with February, values were (11.0 and 14.0 cm/plant)during 1<sup>st</sup> and 2<sup>nd</sup> season respectively.
