疏花疏果对黄皮果实发育和成熟度的影响初探

以鸡心黄皮为试材,研究了3种不同疏花疏果措施对黄皮果实发育和成熟度的影响,结果表明:与不作任何修剪对照相比,3种疏花疏果处理均能显著提高同一果穗中的正常果比例;除了果穗修剪处理的单穗果数明显低于对照、单果重和果实大小高于对照外,人工疏果处理和花穗修剪处理的影响不太明显;3种疏花疏果处理均显著提高了果实的成熟整齐度,而且人工疏果处理还起到了推迟果实完全成熟的作用;此外,3种疏花疏果处理的果实可溶性固形物含量接近,但都低于对照.

Preliminary study on the effects of flower and fruit thinning on fruit growth and maturity of Wampee

The effects of three flower and fruit thinning treatments on the fruit growth and maturity of wampee(cv.Jixin) were studied in this paper.The results showed that compared with the control,three treatments significantly improved the proportion of normal fruit in the same bunch.The treatment of fruit bunch-cutting could significantly decrease the fruit number in single bunch and improve the mass and size of single fruit;while the treatment of artificial fruit and flower bunch-thinning couldn't.Three treatments significantly improved the uniformity of fruit maturity and the artificial fruit-thinning treatment delayed the fruits fully maturating.Besides,the soluble solids contents of fruit with three treatment were all similar to one another,but lower than the control.
