Effects of plant growth regulators on yield and quality of Korla Fragrant Pear
摘要
Abstract
In order to clarify the effects of plant growth regulators in production of Korla fragrant pear (Pyrus brestschneideri Rehd.), the ifeld experiment was carried out to investigate effects of different plant growth regulators on yield and quality with the 20 a Korla fragrant. Plant growth regulators include PBO, PP333 and Sodium Nitrophenolate. The experiment consisted of 17 treatments:different concentration levels and species plant growth regulators, clean water and spraying nothing treatments, a total of 17 treatments, and each treatments was repeated 3 times. The results showed that spraying plant growth regulator can significantly improve the yield. In addition, spraying plant growth regulator not only can reduce the pericarp thickness, fruit hardness and fruit total acid content signiifcantly, but also can increase the fruit calyx dropping rate, fruit lfush rate, fruit reducing sugar content and vitamin C content signiifcantly. The positive effect of treatment that spraying 300 times reagent concentration of PBO was the most remarkable. This treatment can improve these indicators that fruit yield, fruit flush rate, fruit calyx dropping rate and fruit reducing sugar content by 63.41%, 42.01%, 38.97%, and 22.22% when comparing with the control treatment. Furthermore, the treatment also can reduce these indicators that the pericarp thickness, fruit hardness and fruit total acid content by 26.44%, 13.42%and 31.3%.关键词
