复合试剂"M"和PBO对库尔勒香梨产量和果实品质的影响
Effect of Compound Reagent "M" and PBO on the Yield and Fruit Quality of Korla Fragrant Pear
摘要
Abstract
[Objective] This project aims to compare the effects of compound reagent "M" and PBO on calyx dropping rate, fruit setting rate and fruit quality index of Korla fragrant pear in order to provide application technology and theoretical basis for its high yield, good quality and sustainable development.[Method]The Korla fragrant pear at full-bloom stage was used as test materials to determine the calyx dropping rate, fruit setting rate and fruit quality treated with different concentrations of compound reagent "M" and PBO.[Result]The calyx dropping rate, fruit setting rate and fruit quality of Korla fragrant pear were significantly increased after spraying different concentrations of compound reagent "M" and PBO, among which, the M1 treatment had the most significant effect, its non-calyx fruit rate, fruit setting rate of flower were 83.3% and 11.7%, 42.1% and 4.8% respectively higher than those of the CK (control), 18.4% and 2.6% respectively higher than those by PBO treatment;The anthocyanin and chlorophyll contents of M1 treatment were the highest, which were significantly higher than those by PBO treatments, but its carotenoid content was the lowest;Compared with CK, VC content, sugar content, soluble solid content and solid acid ratio of Korla fragrant pear were significantly increased than those by both PBO and M1 treatments, but Tannin content and titratable acid content were significantly decreased.Among them the M1 treatment had a significantly higher sucrose and total sugar content than the PBO treatment.The fructose content was significantly higher than that of PBO treatment and its tannin content was significantly lower than that of PBO treatment, and there was no significant difference among other fruit quality indexes.[Conclusion]The compound reagent M1 sprayed at full-bloom stage can significantly increase the non-calyx fruit rate, fruit setting rate and fruit quality, which has popularization value in production of high yield and good quality of Korla Fragrant Pear.关键词
