This paper studied the effects of debagging time and picking off leaves around fruits on the fruit quality and 1-year old shoots stored nutrition of "Red Fuji" apple. Properly advancing debagging time significantly increased the mean mass, anthocyanin content, and coloration area of the fruits (P < 0.05). Comparing with those of the fruits debagged on September 30, the mean mass, anthocyanin content, and coloration area of the fruits debagged on September 24 increased by 10.98%, 28.15%, and 13.44%, respectively, and the fruit firmness, soluble solid content, and titratable acidity had less differences. When the leaves within 15, 30, and 45 cm away from the fruits were wholly picked off, the light environment around the fruits improved significantly (P < 0.01), with the light intensity increased by 70%, 95%, and 115%, respectively, compared with no leaf picked off treatment. Picking off the leaves within 30-45 cm away from the fruits benefited the fruit coloration and anthocyanin accumulation. No significant effects were observed on the 1-year old shoots stored nutrition and their budding in next year among the treatments of picking off leaves. Advancing debagging time and picking off the leaves within 30-45 cm away from the fruits could improve fruit appearance and quality.
本文研究了摘袋时间和摘除果实周围叶片对“红富士”苹果果实品质及一年生枝条贮藏营养的影响。适当提前摘袋时间可显著提高果实的平均质量、花青素含量和着色面积（P<0.05）。与9月30日摘袋的果实相比，9月24日摘袋的果实平均质量、花青素含量和着色面积分别提高了10.98%、28.15%和13.44%，果实硬度、可溶性固形物含量和可滴定酸含量差异较小。当摘除距离果实15、30和45厘米范围内的叶片时，果实周围的光照环境显著改善（P<0.01），与不摘叶处理相比，光照强度分别增加了70%、95%和115%。摘除距离果实30 - 45厘米范围内的叶片有利于果实着色和花青素积累。摘叶处理对一年生枝条贮藏营养及其翌年萌芽无显著影响。提前摘袋时间并摘除距离果实30 - 45厘米范围内的叶片可改善果实外观和品质。
