不同药剂处理对黄金梨脱萼果率和果实品质的影响

摘要

In order to improve ratio of fruits without calyx in Whangkumbae, effects of different reagents on ratio of fruits without calyx and fruit quality in Whangkumbae were researched, through spraying different concentrations of PBO and lfusilazole at lfower bud period and initial bloom stage. The results show that the ratio of fruits without calyx reach the highest value (64.29%) in the treatment of spraying 300 times PBO at initial bloom stage, which is signiifcantly higher than the contrast. In the treatment, the ratio of the fruits with residue calyx is 4.76%, lower than that of the others, and the contents of total sugar, total acid and soluble solids are the highest, are respectively 9.1%, 0.24%and 14.3%, which are higher than the contrast. The single fruit masses in all treatments are higher than the contrast, but the differences are not signiifcant.%为提高黄金梨的脱萼果率，在黄金梨的现蕾期和露白期分别喷施不同浓度的保花保果剂(PBO)和福星（氟硅唑），研究了不同药剂对黄金梨脱萼果率和果实品质的影响。结果表明：经不同药剂处理后，以在露白期喷施300倍PBO处理果实的脱萼果率最高，达64.29%，显著高于对照；残萼果率较低，仅为4.76%，且其总糖含量、总酸含量和可溶性固形物含量最高，分别为9.1%、0.24%和14.3%，均高于对照。经不同处理后果实的单果质量均高于对照，但差异不显著。
