四种植物生长调节剂对玫瑰香葡萄无核化及果实品质的影响
Effects of four plant growth regulators on inducing seedless fruit and quality of Muscat Hamburg grape
摘要
Abstract
[Objective]Effects of plant growth regulators on inducing seedless Muscat Hamburg grape were investigated to provide seedless processing technique for Muscat Hamburg grape production in Guangxi.[Method]Seven different treatments of 4 different rations and concentrations of GA3,CPPU,ABA and KT30 were applied,with water as the control.Inflorescences with coincident growth were selected as experimental subjects randomly.First,spikes were immersed 2 days before flowering,and repeated 15 days later.After maturity,the single fruit weight,size,shape index,hardness,seedless percentage and total soluble solid were determined.[Result]The seedless percentage was improved in all the seven treatments with the similar fruit size of the ordinary cultivated fruit.Treatment 1 produced the best fruit with seedless percentage of 86.0％.[Conclusion]Seedless Muscat Hamburg grape can be induced by the plant growth regulators with different ratios and proportions.When the grape was first treated by GA3 (20 mg/L) two days before flowering,then treated by mixtures with GA3.KT-30 and ABA at levels of 10 mg/L,2 mg/L and 10 mg/L,the seedless fruit with identical size of ordinary cultivated fruit could be obtained.关键词
