This study was carried out at the nursery of Horticulture Research Institute, Giza, Egypt in the two seasons, 2016 and 2017, aiming to investigate the effect of salicylic acid at different level (0, 0.5, and 1.0 g/l) with different levels of field capacity (25,50,75 and 100%) on growth and chemical constituents of Taxodium distichum and also to reduce the amount of water needed for irrigation. Main results of this study could be summarized as follows: The highest value was achieved by the following treatments: salicylic acid at 0 g/l with100% of field capacity level (concerning root fresh and dry weights); salicylic acid at 0.5 g/l with 75% of field capacity level (for plant height, branch number, shoot dry weight, root fresh and dry weights); salicylic acid at 0.5 g/l with 100% of field capacity level (regarding plant height, branch number and root length); salicylic acid at1.0 g/l with 75% of field capacity level (for plant height, root length and root fresh weight); and salicylic acid at 1.0 g/l with 100% of field capacity level (for shoot fresh weight, total carbohydrate and total chlorophyll). The lowest value was obtained by the following treatments: salicylic acid 0 g/l with 25% of field capacity level (for plant height, branch number, shoot fresh and dry weights, root fresh weight, total carbohydrate and total chlorophyll); salicylic acid at 0 g/l with 50% of field capacity level (for plant height and shoot dry weight); salicylic acid at 0.5 g/l with 25% of field capacity level and salicylic acid at 0.5 g/l with 50% of field capacity level (for root fresh weight); salicylic acid at 0.5 g/l with 100% of field capacity level (for root dry weight); salicylic acid at 1.0 g/l with 25% of field capacity level (for root length and shoot dry weight); and salicylic acid at 1.0 g/l with 50% of field capacity level (for shoot dry weight). It is recommended to treat plants with salicylic acid at 0.5 g/l and to apply irrigation at 75% of field capacity level capacity to obtain the highest values of plant height, branch number, shoot dry weight, root fresh and dry weights. This will also save as much water as 25% of field capacity level.

The purpose of this study was to quantify ginning efficiency and fiber quality for regional cotton cultivars ginned on commercial style equipment. Results should allow plant breeders and ginners to consider improvements in cotton cultivars that are in response to ginning conditions that more nearly reflect commercial ginning practices. Therefore, the seed cotton

In a trial to solve some of the most important problems facing the production and quality of Iris tingitana cv. Wedgewood plant under local conditions in Egypt including the short and late blooming season in spring. Moreover, the study aimed also to solve the problem of the deterioration of bulbs productivity year after year. So, two separate field experiments were conducted throughout two successive seasons

the two years, 2016 and 2017, aiming to investigate the effect of salicylic acid at different level (0, 0.5, 1.0 and 1.5 g/l) on growth and chemical composition of Taxodium distichum under salinity stress at four concentrations (0, 4, 6 and 8 g/l NaCl). The results revealed that, salinity levels significantly decreased growth parameters, i.e. seedlings height, branches number, root length and shoot, root fresh and dry weight. Also, salinity decreased total carbohydrate content and total chlorophyll content in leaves. Salicylic acid application significantly increased growth parameters under salinity stress as compared with salinity treatment without salicylic acid application. Application of 0.5 g/l salicylic acid recorded the best results. Also, combinations that occupied the highest position were: salicylic acid at 0.5 g/l with salinity at 4 and 6 g/l for shoot dry weight and root fresh weight; salicylic acid at 0.5 g/l with salinity at 0 g/l for branch number, root length; salicylic acid at 0.5 g/l with salinity at 4 g/l for plant height 2 nd year, root dry weight and total chlorophyll content; salicylic acid at 0.5 g/l with salinity at 6 g/l for plant height in the 1 st year and root dry weight; salicylic acid at 1.0 g/l with salinity at 0 g/l for branch number in the 1 st and 2 nd years and shoot fresh weight; in addition to salicylic acid at 1.0 g/l with salinity at 4 g/l, salicylic acid at 1.5 g/l with salinity at 0 g/l and salicylic acid at 1.5 g/l with salinity at 4 g/l for shoot fresh weight. Combinations that obtained the lowest grade were: salicylic acid at 0 g/l with salinity at 8 g/l for root length, root fresh weight, root dry weight, total carbohydrate content and, total chlorophyll content. It is recommended to in case of irrigation water or soils afflicted with salinity, it is advised to apply salicylic acid at 0.5-1.5 g/l as to alleviate salinity stress. So that it could be concluded that the addition of 0.5-1.5g/l of salicylic acid are beneficial to mitigate the adverse effects of salinity stress of T. distichum seedlings.
