Evaluation Effect of Seed Priming (Salicylic acid and Methyl jasmonate) on Crop Production and Biochemical Traits of Bread Wheat

BACKGROUND: Salicylic acid and methyl jasmonate have been recognized as playing a pivotal role in regulating physiological processes and as an important molecular signal in plant oscillations in response to environmental stresses. OBJECTIVES: Current research was done to assess response of biochemical characteristics and yield of Wheat varieties to use salicylic acid and Methyl jasmonate. METHODS: This research was done in Lab via factorial experiment based on completely randomized design with four replications along 2019-2020 year. Also current study was done in farm according factorial experiment based on complete randomized block design with four replications. The treatments included seed priming (Control or seed treatment with distilled water, Seed treatment with 0.15 mM salicylic acid and 1.5 μM Methyl jasmonate) and Wheat Varieties (Chamran and Mehrgan). RESULT: Result of analysis of variance revealed effect of seed priming, varieties and interaction effect of treatments (instead grain yield) on all measured traits was significant. Mean comparison result of different level of seed priming indicated that maximum amount of grain yield (0.445 kg.m -2 ), leaf area ratio (0.833 m 2 .kg -1 ), Spike length (6.212 cm), Superoxide dismutase (339.603 gr leaf protein) and Glutathione peroxidase (4.548 gr leaf protein) were noted for Methyl jasmonate 1.5 micro molar and minimum amount of those belonged to control treatment. Also compare Wheat varieties revealed Chamran verity was superior in compare to Mehrgan verity. Evaluation mean comparison result of interaction effect of treatments indicated maximum leaf area ratio (0.846 kg.m -2 ), spike length (6.375 cm), Superoxide dismutase (350.460 gr leaf protein) and Glutathione peroxidase (4.835 gr leaf protein) belonged to Methyl jasmonate 1.5 micro molar and Chamran variety and lowest ones belonged to control and Mehrgan variety. CONCLUSION: Generally based on result of current study application salicylic acid and Methyl jasmonate led to improve grain yield and biochemical traits of Wheat verities and can be advised to farmer.
