Abstract

A laboratory experiment was conducted at Giza Central Seed Testing Laboratory of Central Administration for Seed Certification (CASC), Ministry of Agriculture, Egypt. Seedling parameters i.e. shoot and root length, shoot and root fresh weights, shoot and root fresh dry weights; seedling height reduction and relative dry weight were estimated. Highest averages of shoot and root lengths, shoot and root fresh weights, shoot and root dry weights, seedling height reduction and relative dry weight were produced from seed priming in NaCl or KNo3. Line 168 cultivar surpassed other studied cultivars in of shoot and root length, shoots and root fresh weights, shoots and root fresh dry weights, seedling height reduction and relative dry weigh. Increasing salinity levels from 0 to 3, 6, 9, 12, 15 and 18 dSm-1 NaCl significantly decreased all studied characters except seedling height reduction percentage which was increase. Shoot length, shoot and root fresh weights, root dry weights, seedling height reduction and relative dry weight significantly affected by the interaction between seed priming treatments and cultivars. Shoot length, shoot and root fresh weights, shoot and root fresh dry weights, seedling height reduction and relative dry weight significantly affected by the interaction between cultivars and salinity concentrations, by the interaction among seed priming, cultivars and salinity concentrations. It could be concluded that seed priming in in NaCl or KNo3 of Line168 or Line 1697 cultivars were more tolerant to salinity stress, which must be put in breeding program of safflower for enhancing of safflower productivity under salinity conditions.
