Effect of Putrescine Application and Drought Stress on Germination of Wheat (Triticum aestivum L.)

28856

One of the important food and essential crops is wheat (Triticum aestivum L.). Drought stress as a major detrimental factor leads to ultimately reduce crop yield in arid and semiarid regions. In order to study the effects of different concentrations of putrescine on the germination stage of wheat under drought stress, this experiment was carried out as factorial based on completely randomized design with four replications. Final germination percentage (FGP), mean germination time (MGT), coefficient velocity germination (CVG), rate index (RI) germination rate index (GRI) and seedling vigour index (SVI) data were obtained. Analysis of variance indicated that putrescine, osmotic potential and their interaction were significant for the trait mentioned above. When PEG 6000 increases. FGP, CVG, RI, GRI and SVI significantly decreased, whereas the MGT increased. In addition, putrescine, particularly the concentration of 1 mM, decreased the adverse effect of drought created by PEG 6000. In other words, it elevated the rate of FGP, CVG, RI, GRI and SVI, and lowered MGT. The results suggested that putrescine increased the osmotic stress tolerance of wheat germination stage
