Abstract

Adverse effects of water stress without ions interactions in Baraka, Adlib and Nineveh lentil cultivars have been investigated. Results showed that germination under saturation (0 AWC depletion %) was the paramount treatment as it manifested the highest values. It profoundly surpassed that of 25, 50, and 75 AWC depletion % in terms of final germination percentage (3.9, 7.3, and 22.9), germination rate (51, 66.2 and 97.7%), radical length (65.9, 127.5 and 204.9%), plumule length (51.7, 127.5 and 430.6%), respectively. Additionally, this treatment highly reduced the days required for peak germination. Regression analysis revealed that final germination percentage was linearly responded to different moisture and can be forecasted by the following equation: Y= 100-0.234X where, (r2=36.6). Mungbeans was the most potent cultivars, which significantly surpassed Nineveh, Adlib, Baraka and Common Vetch in final germination (3.3, 2.6, 4.3 and 17.8%), plumule length (102.7, 82.5, 119.6 and 96.4%), respectively. It also unveiled superiority in shortening the time required for peak germination, days required for first emergence and radical plumule lengths, in compression to other cultivars. These results suggested that the superiority order should be as follow: Mungbean > Adlib > Nineveh > Baraka >Common Vetch. Adlib seed germinated on filter paper saturated by distilled treatment shoed preponderance other interaction treatments in radical length (121.25 mm). Moreover under severe water deprivation (depletion of 75% AWC), Adlib dominance was also unveiled as it gave the highest radical length (51.25 mm), final germination percentage (90%), respectively.
