Abstract

In a pot experiment, the growth (Dry matter) responses of 18 RAPESEED varieties to three levels of NaCl salinity induced by 1.2, 6, and 12 dS.m-1 were investigated using a factorial experiment with a randomized complete block design in 3 replications. The results indicated that salinity reduced total dry matter, Na concentration, K/Na ratio, ION SELECTIVITY of K versus Na, and leaf WATER POTENTIAL while it increased K concentration. However, the leaf WATER POTENTIAL of the plants had the highest and a significantly negative correlation with total dry matter accumulation. Therefore, it seemed that leaf water content of the plants could explain the tolerance or sensitivity responses to salinity. The RAPESEED varieties were accordingly ranked into different groups. The varieties viz, Alice, Fonax, DP.94.8 and Licord were classified as saline tolerant group, and varieties such as Okapi, Akamar and Eurol as saline sensitive group. The remaining eight RAPESEED varieties were moderately tolerant. Moreover, the response of RAPESEED varieties viz. Consul, VDH8003-98 and Orient were different such that the above explanation could not be applied to them. Therefore, halophytic strategies for these three varieties might be worth further investigation.
