Effect of anti-transpirant and auxin on wheat (Triticum aestivum L.) grain yield, yield-related traits, and germination |

| چکیده انگلیسی مقاله |
Objective: The grain yield of wheat is always limited by drought in arid and semiarid areas. Field and laboratory experiments were conducted to investigate the effects of anti-transpirants and auxins on grain yield, yield-related traits, and germination of wheat.
Methods: The field experiment was carried out in the Chamchamal Plain of Kermanshah, Iran, using a split-plot design with three replications. Concentrations of auxin (0, 50, and 100 ppm) were arranged in main plots, and anti-transpirant (sunflower oil) concentrations (0, 5, and 10%) in subplots. 2,4-D + MCPA (2-methyl-4-chlorophenoxyacetic acid) were used as auxins. At the harvesting time (June 20, 2014), several agronomic characteristics, including grain yield and single-grain weight, were measured. In addition, a laboratory experiment was conducted by choosing random seeds from the mother plants in the field experiment to study the effect of anti-transpirant and auxin on germination characteristics, including germination percentage, caulicle length, and radicle length.
Results: Results showed that auxin application of 100 ppm had the lowest single-grain weight. Anti-transpirant and auxin application had no significant effect on grain yield. Auxin concentration of 100 ppm with an anti-transpirant application rate of 0%, and an auxin application rate of 100 ppm with an anti-transpirant concentration of 10% resulted in the lowest harvest index. Also, the auxin concentration of 100 ppm with an anti-transpirant application rate of 10% had the lowest seed germination. This is probably because hormonal and oil agents have mediated the increase in wheat seed germination inhibitors.
Conclusion: Using auxin and anti-transpirant in the reproductive stage didn’t have a positive effect on grain yield, yield-related traits, and germination of seeds from mother plants in wheat. Also, auxin had a negative effect on the single-grain weight. Therefore, the studies about the effect of herbal anti-transpirants and auxin at the vegetative stage of wheat are recommended to gain further insight about the effectiveness of these compounds on agronomic traits in wheat. |
