摘要:
以18年生皮球桃为试材，研究探讨了外源钙（CaCl2、Ca(NO3)2）对叶、茎、果实钙含量以及果实品质的影响。结果表明：不同时期叶片中的钙含量变化相对较平稳；果肉和果核中钙含量从果实硬核期到膨大期逐渐升高，达到一定量后逐渐降低，采前1个月钙含量基本趋于平衡；在果肉和果核的钙含量达最大时茎钙含量最低，果肉和果核中钙含量降到低点时茎钙含量达最大；果实的横、纵、侧径增长趋势基本一致，从硬核期到成熟，生长曲线呈‘快-慢快’型增长；Ca(NO3)2处理果实单果重最重，为219.19 g；CaCl2处理果实可溶性固形物和可溶性糖含量最高，分别为12.1%、9.24%。
Abstract:
Taking 18-year-old Piqiu peach as material,the effect of calcium application（CaCl2,Ca(NO3)2） on calcium content of leaf,stem,pulp and fruit quality of peach were discussed.The results showed that the change of calcium content in leaf was relatively smooth in different periods.The contents of calcium in the pulp and the fruit stone were increased gradually during the stage from fruit hardcore to fruit expanding,gradually decreased when reaching a certain amount,and maintained a basic balance level at one month before harvesting.The calcium content in stems was the minimum when its content in the pulp and the fruit stone were the largest,and was the highest when its content in the pulp and fruit stone were the lowest.The length diameter,cheek diameter and suture diameter of peach fruit showed the same growth trends,and their growth curve presented as ‘fast-slow-fast’.The single fruit weight dealed with Ca(NO3)2 was the heaviest 219.19 g,the soluble solids and soluble sugar content dealed with CaCl2 were the highest (12.1%,9.24%).
