Roll of Gibberlic Acid and Sprimidin on Germination of Spring Cultivars of Wheat Under Salinity Stress
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 9
Abstract
Objective: In order to Investigate effects of Gibberlic acid (GA3) and Sprimidin Poly Amine on Germination of three Cultivars of Wheat under Salinity Stress. Methods: The experiment was conducted as factorial based on completely randomized design with four replicates in Agronomy and plant breeding laboratory of Agricultural department of Islamic Azad University, Varamin-Pishva branch in spring of 2014. The first factor was salinity with four levels (S1: 3.87 ds/m, S2: 5.95 ds/m, S3: 10.25 ds/m and S4: 12.87 ds/m) and the second factor was three cultivars of spring wheat including V1: Tajan, V2: Arg and V3: Pishtaz and the third factor 4 levels of hormone including H0: control (not application of hormone), H1: GA3 100 mg/L, H2: sprimidin 5 mmol/L and H3: GA3 100 mg/L + sprimidin 5 mmol/L. coleoptile and cleorhiza length, cleorhiza number, coleoptiles, cleorhiza and seedling dry weight, tissue water content (TWC), germination percent and number of damaged seeds were measured. Results: Analysis of variance showed that coleoptile and cleorhiza length, cleorhiza number, seedling and cleorhiza dry weigth affected by salinity, hormone and cultivar treatment at 1% of probability level. There are no significant differences for other properties. Results of this experiment indicated that even application of these treatments, development processes of germination under salinity stress decreased greatly.
