Abstract

In order to investigation of GA3 and KINETIN effects on GERMINATION parameters and seedling growth of WHEAT (Triticum aestivum cv. Flat) under SALINITY STRESS, we conducted a factorial experiment design with 4 levels of GA3 (0, 1.5, 3 & 4.5 mg lit-1) and KINETIN (0, 1, 2 & 4 mg lit-1) at 4 levels of salinity that prepared by 0, 70, 140 & 210 mMole NaCl. ANOVA of studied traits at GERMINATION and seedling growth phases showed that GERMINATION percentage, seed GERMINATION and seedling growth rate, root and shoot length decreased dramatically by increasing of salinity. Increasing of exogenous GA3 concentration led to increasing of shoot length and water tissue content at different levels of salinity but it had an inhibitory effect on GERMINATION rate. The high concentration of KINETIN (mg lit-1) led to increasing of shot length and shoot/root ratio seriously. There were interaction between GA3 and KINETIN in related to seedling growth parameters at salinity levels. GA3 and KINETIN treating increased seedling water content. Se of this experiment results and development of researches in related to exogenous application of plant growth regulators can be lead to better understanding about physiological mechanisms of plant tolerance to environmental stresses.
