Effect of Salt Hardening and Salt Stress on Germination of Some Cucumber Varieties Abd alaziz al Ali 1 ABSTRACT The experiment was conducted at Horti Lab, Agric Facultyal Furat Univ during 005006 seasons to evaluated the responses of three cucumber varieties to salt stress and hardening at germination stage in order to selection of salttolerant varieties Complete block design with 3 replications was used The studied factors were salt concentrations 0, 03, 06, 08 and 1% NaCl, varieties Condor, Lama and Field master, beside two salt hardening treatments of seeds 0 and 3% NaCl Results showed significant differences between varieties and salt concentrations in terms of germination, rootlet, plumule length and the sedling live fresh weight of the living seedling Field master surpass over the two others varieties for all studied traits On the other hand, increased salt concentration in growth media caused growth inhabitation, except at nd treatment, where a 1% NaCl treatment resulted on rootlet and plumule death at the initial formation stage Moreover, results showed increase of the variety tolerance by salt hardening, where alleviated the negative effect of salinity, especially in the higher concentration 1% NaCl Field master recorded a better response to salt hardening Also, variation analysis showed exchangeable reaction between cucumber varieties, salt hardening and salt at all concerned characteristics, which means that variety reactions differed at each level of salt hardening and salinity Key words: Salt stress, Salt hardening, Germination, Cucumber, Varieties 1 Asst Prof Horti Dept, Agric Faculty, AlForat Univ 48
