Abstract
Salinity is considered as one of important physical factors influencing rice production. Soil salinity harmful influenced germination characters of rice cultivars Salinity is the main limiting factor that adversely affecting germination, growth and yield of rice. A laboratory experiment accompanied in the Giza Central Seed Testing Laboratory of Central Administration for Seed Certification (CASC), Ministry of Agriculture Egypt during May and June 2017. In order to investigate the salt tolerance of rice cultivars using some physiological parameters, i.e. germination stress, tolerance index, promptness index, shoot length, stress tolerance index, root length stress and tolerance index. Sakha 106 surpassed other cultivars promptness index, germination stress tolerance index, shoot length stress index, root length stress index, shoot fresh stress index, root fresh stress index, Shoot dry fresh stress index, root dry stress index. Sown Sakha 106 cultivar exceeded Sakha 104 cultivar by 34.64% in germination stress tolerance index and 14.90 % in shoot height stress index and 30.26% in root fresh stress index. Sakha 106 cultivar exceeded Sakha 101 cultivar by 22.15 % in root dry stress index. Sakha 106 cultivar exceeded Giza 178 cultivar by 8.97 % in root height stress index and by 26.58 % shoot fresh stress index and by 20.70 % in shoot dry stress index. Humic acid at 500 ppm surpassed other antioxidants in germination stress tolerance index, shoot length stress index, root length stress index, shoot fresh stress index, root fresh stress index, shoot dry stress index and root dry stress index. Salinity level of 100 mM exceeded all salinity concentration in germination stress tolerance index, shoot length stress index, root length stress index, shoot fresh stress index, root fresh stress index, shoot dry fresh stress index, root fresh stress index, shoot fresh stress index, shoot dry fresh stress index, root fresh stress index. Increasing salinity concentration up to 300 mM decreased germination stress tolerance index, shoot length stress index, root length stress index, root fresh stress index, shoot fresh stress index, shoot dry stress index and root fresh stress index by 52.4, 38.6, 40.4, 39.5, 47.6 and 49.8 %, respectively. In general, in order to maximize physiological indexes parameters by priming seeds of Sakha 106 cultivar in Humic acid at 500 ppm. It can be used in breeding program to boost production in Egyptian territory.
