| Abstract | ||
| The study was conducted in one of Abu Khasib orchards in Basra governorate during the spring season of 2012 in silty soil mixture .the aim of this search to study the effecting of seed soaking by some growth regulators ethephon, naphthalene acetic acid, Salicylic acid and Ascorbic acid in addition to the control treatment of "Cucumis sativus" local variety by 100 mg / l for 10 hours a ،soaking with distilled water، on the physiological, growth and production characters and hormone content in the leaves of plants. The results showed there were a significant increase in all growth regulator treatments compeers with control in the vegetative growth, flowering and production. The ascorbic acid was recorded more influence on number of lateral branches, the number of total leaf, leaf area, number of flowers feminine, sex ratio, number of fruits and production of the plant in comparison with control wich reach ،16.004 and 3940 and 35.23 and 83.57 and 73.68 and 48.41 and 70.27،, respectively. The leaf hormonal content of IAA , GA3 and cy were recorded a significantly increased in plants soaked seeds for ascorbic acid in comparison with control treatment while content of ABA increased significantly in plants soaked seeds by ethephon compared with the control treatment. | ||
