摘要
巨峰葡萄采后落粒严重，果梗易失水干枯，贮运难度大，在常规贮藏条件“低温、高湿、防腐”情况下，仅能较好地贮藏３个月左右。应用一定浓度的植物生长调节物质２，４—Ｄ、ＰＣＰＡ、ＮＡＡ等在采前３～５天喷洒果穗，可改善巨峰葡萄贮运性能。其中用“防落１号”处理的果实在上述条件下贮藏４个月以上，腐烂、落粒不超过５％，其中落粒低于２％。采后生理测定表明，“防落１号”处理的果穗，贮藏期间果梗耐拉力增加，呼吸强度低于对照果实，Ｖｃ含量高于对照果实。
The post-harvest berry drop of'Ju Feng'grape is severe,main stalk and fruit stem easy to lose water and wither,not easy to maintain its fresh state during storage and transportation.Under the condition of low temperature,high humidity and anti-rot,it can be stored well only for three months.Spraying certain growth regulators in different content 3￣5days before harvest,for example,2,4-D,PCPA and NAA,can improve the storage and transportation property of'Ju Feng'grape.Berry fruit sprayed with No.1 Anti-drop(a treatment among many prescriptions)can be stored for more than 4 months under the condition mentioned above. Their proportion of rot and berry drop are not more than 5% among which berry drop lower than 2%.Post-harvest physiological measurement showed that spraying with No.1 Anti-drop can increase berry's adhesive force on the stalk,reduced berry's respiration and increased Vc content of berry during storage.
