Effect of Application of Putrescine on Seedling Growth and Cell Division of Wheat (Triticum aestivum L.) under Drought Stress

Abstract

Wheat has been a staple crop for thousands of years and is of massive economic importance worldwide. The study was conducted to evaluate the effect of drought and putrescine hormone on the seedling growth parameters and cell division of wheat genotypes. Wheat genotypes seeds (Kırmızı Kılçık, Hawk, Pehlivan and Müfitbey) were primed with four levels of putrescine (0.01, 0.1 and 1 mM and distilled water as control), then kept under drought stress induced by polyethylene Glycol (PEG 6000) at different concentrations [0 (distilled water), -2, -4, -6, -8 and -10 bar] for 10 days. Experiment was arranged as factorial in a completely randomized design with four replications. At the end of 10 days, root number, root, coleoptile and shoot length and mitotic index (MI) data were obtained. Analysis of variance indicated that genotype, putrescine, osmotic potential and their interaction were significant. While PEG 6000 osmotic potential increases, root number, root, coleoptile and shoot length and mitotic index (MI) significantly decreased. In addition, particularly 1 mM putrescine has decreased the adverse effect of drought created by PEG 6000. Based on the comparison of genotypes, Kırmızı Kılçık was selected as tolerant to drought stress whereas Pehlivan was identified as susceptible.
