Effect of priming with proline on the performance of two wheat cultivars

Abstract

Amino acids (bio-stimulants) are considered as cheap and biodegradable chemicals that increased yield and agronomic performance of several crops. A field experiment was conducted at the experimental station of National Research Centre, Nubaria district El-Behera Governorate-Egypt, during two winter seasons. Grains of two wheat cultivars (Misr 3 and Sids 12) were soaked with proline at 5 or 10 mM for 12 hours and dried at room temperature before sowing to study the effect of proline treatments on the performance and quality of wheat plants grown under sandy soil conditions. Data show that performance of Misr 3 cv grown under the conditions of sandy soil was more better than Sids 12 cv. Moreover, proline treatments at both concentrations caused significant increases in most parameters measured in this study. It was noted that Misr 3 cv responded effectively to 5 Mm proline, while response of Sids 12 cv was more effective to 10 mM proline. It could be concluded that proline treatments showed promotive effect on quality and quantity of both wheat cultivars grown under sandy soil conditions.
