The Effect of Plant Growth Regulators on the Yield and Quality of Red Grape
S-inducin is a plant growth regulator produced by secondary metabolism of microorganisms,non-toxic,residue free,and safe for food and human health.In order to investigate the effect of S-inducin on the yield and quality of red grape,the author selected 10%S-inducin soluble powder at 2,500 times solution,3,333 times solution,5,000 times solution,10,000 times solution,20,000 times solution,and 0.01%brassinolide soluble solution at 3,333 times solution for irrigation during the grape pommel stage,and measured the yield and quality of the fruit after ripening.The results showed that 10%S-inducer soluble powder can effectively increase grape fruit grain weight,single ear weight,yield,and increase the content of soluble solids,soluble sugars,vitamin C,and procyanidins in red grapes.The recommended application concentration is 2,500-3,333 times the liquid.
