Effect of exogenous treatment of GA3 on germination of wheat seeds under salinity stress
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 6
Abstract
In this study effect of different concentration of gibberlic acid (GA3) (H0: control, H1:GA3 (100mg/litr)H2:GA3 (150mg/litr) H3:GA3 (200mg/litr)) under four levels of salinity stress (S1:3.78, S2: 5.95, S3: 10.25 and S4: 12.87 ds/m) was investigated on germination of Pishtaz cultivar. The experiment was conducted as factorial based on completely randomized design with four replicates in laboratory of agronomy and plant breeding of agricultural department, Islamic Azad University, Varamin-Pishva Branch in 2012. coleoptile and cleorhiza length, cleorhiza number, coleoptile and cleorhiza dry weight, germination percent and number of damaged seeds were measured. There was significant difference among salinity and hormone treatments at 1% of probability level for coleoptile and cleorhiza length, cleorhiza number and dry weight. The results indicated that following increasing salinity, application of GA3 had no significant effect on germination percent, TWC and damaged seeds.
