不同果袋及脱袋时间对“新川中岛”桃果实性状的影响

Effect of Different Type of Fruit Bags and Fruit Bag Removal Times on Fruit Character of 'Hinkawa Nagasima' Peach

以＂新川中岛＂桃为试材,研究了不同材质果袋、不同脱袋时间对桃单果重、果实着色、可溶性固形物、去皮硬度等性状的影响。结果表明：套纸袋优于塑膜袋,套纸袋果实可溶性固形物含量、硬度与无袋果差异不明显,可溶性固形物含量甚至略高于无袋果,脱袋时间以采前5-7d为宜;套纸袋后带袋采收的桃果较无袋栽培果可溶性固形物含量变化不大,不影响果实的甜度、口感等。
