猕猴桃果实成熟前补钙对果实含钙量的影响

Influence of calcium supplementation before fruit ripening on fruit calcium content of kiwifruit

猕猴桃果实成熟前用喷叶法和喷果法补钙 ,可显著提高果实中的钙含量。喷叶较喷果效果好。用Ca(NO3 ) 2 喷叶 ,比用CaCl2 处理效果好 ,差异显著。而果实对CaCl2 和Ca(NO3 ) 2 的吸收选择性差异不显著。经补钙处理的果实采后进行贮藏效果观察发现 :用Ca(NO3 ) 2 喷叶处理的果实贮藏性较好 ,用其喷果处理次之 ;用CaCl2 喷果和喷叶处理的果实贮至 2 8天软果率均达到 90 %。

Calcium supplement before fruit repening by two ways, spraying calcium solution on leaves or berries, could evidently increase calcium level in kiwifruit berries, but the former method was better than the latter. Leaf spraying Ca(NO_3)_2 got a better result than doing CaCl_2, with difference being significant, but the difference in selective absorption of Ca(NO_3)_2 and CaCl_2 by berries was not significant. It was observed that the berries harvested from the vines which received leaf spraying Ca(NO_3)_2 were better at storage property. The soft fruit ratio of either spraying CaCl_2 on leaves or on berries was 90%, when kiwifruit berries were stored for 28 days.
