Abstract

Drought stress is one of the most important environmental factors that it is effective on growth, development and production of plants. This investigation was conducted to evaluate the effects of the drought stress on seed GERMINATION of CARTHAMUS cultivars, in order to an experimental factorial was conducted based on randomized complete block design (CRD) with three replications. The experimental factors were four cultivars) Hatman, CW-74, Yenice and LRV-5161) with five levels water stress (0,-2,-4,-6,-8 bar). The results showed that different treatments of drought stress had considerable effect on the GERMINATION percentage, uniformity of GERMINATION, radicule and plumule weight, and proportion of radicle to plumule and seedling total dry matter. Increasing osmotic potential decresded GERMINATION percentage, it the amount was 81/02% in control treatment and 6/03% osmotic potential -8 bars. The highest GERMINATION percentage was belonged to CW-74 cultivar (62/9%) and the least it was in Yenice cultivar (42/66%). Maximum uniformity of GERMINATION was obtained in control treatment and the least it was in osmotic potential -6 and -8 bar. Cultivars had different response to drought stress. Minimum uniformity of GERMINATION was obtained in LRV-5161 cultivar (with 53/47 hours) and maximum it was in CW-74 cultivar (with 42/71 hours). Under water stress condition CW-74 cultivar had longer radicle and higher proportion of radicle to plumule than the other cultivars. Study of the other parameters such as radicule and plumule weight, seedling total dry matter showed that CW-74 cultivar was more resistance to water stress.
