Studies Of Efeect Of Plant Growth Regulators On Berry Of Seedless Grape In Xinjiang

Xinjiang is the biggest area of grape,where possess unique climate and soil which fit high quality of grape fruit,and is the base of high quality and safety grape.Thompson of seedless is famous to worldwide. Because of convenient and good taste,Seedless grape is the trend of developing the table grape.At the same time,seedless grape possess good market prospect.Make the eminent seedless grape as the test material,we researched the effect of plant growth regulations.the aim of the research is to supply key technique of producing high quality seedless grape to the growther,and to privode guide of using PGRs in seedless grape.Thus the use of PGRs is more safety and more reasonable,to raise the quality of seedless grape. We expect every grape variety reach the best result and raise the rate of commodity of grape.The study adopt Monukka seedless grape, Centennial seedless grape, Crimson seedless grape, Flame seedless grape, Superior seedless grape as material,and spraying different PGRs on these xinjiang major seedless grapes. We according to the property of every seedless grape designing different kinds,concentration,time and frequency of PGRs. Now we grasp the suitable kinds.concentration.time and frequency of PGRs to the five seedless grape.The result of the research include:1. The response is not the same to applying the different PGRs in different seedless grape.we should make a try before popularizing in big area in case of large loss.2. The different treatment of the test can improve the appearance quality to Monukka seedless grape, e, Centennial seedless grape, Crimson seedless grape, Flame seedless grape, Superior seedless grape.in the same time,which can produce both positive and opposite effect. Overall,the effect of the treatment 4,8,11 is perfect to Monukka seedless grape.that it to say before flower 75mg/l GA, blossom 100mg/l GA, after flower 120mg/l GA+ 30mg/l Brassinolide or before flower 100-150mg/l Qibao,after flower 0.71ml/l Guomei or 30mg/l Brassinolide and 100mg/l 6-BA can progress the quality of Monukka seedless grape,which can popularize with big scale;the effect of the treatment 5,8 is perfect to Centennial seedless grape, that it to say only after flower 40mg/l GA+50mg/l 6-BA or 0.71ml/l Guomei can progress the quality of Centennial seedless grape,which can popularize with big scale;the effect of the treatment 4 is perfect to Crimson seedless grape, that it to say after flower 50mg/l GA+15mg/l Brassinolide can progress the quality of Crimson seedless grape,which can popularize with big scale;the effect of the treatment 4,11 is perfect to Flame seedless grape, that it to say before flower 40mg/l GA,after flower 50mg/l GA+15mg/l Brassinolide or before flower 50mg/l Qibao,after flower 0.35ml/l Guomei+15mg/l Brassinolide and 50mg/l 6-BA can progress the quality of Flame seedless grape,which can popularize with big scale;the effect of the treatment 3, 11 is perfect to Superior seedless grape, that it to say before flower 30mg/l GA, after flower 30mg/l GA+40mg/l Qibao, or before flower 40mg/l Qibao.after flower 0.35ml/l Guomei+15mg/l Brassinolide and 500mg/l 6-BA can progress the quality of Superior seedless grape,which can popularize with big scale.3. The test adopt the popular PGRs in market directly and mixed,for example ProGibb and Guomei etc.Form the result of the test,the effect of the ProGibb and Guomei PGRs is perfect for some kinds,for example Centennial seedless grape,but the effect of the ProGibb and Guomei PGRs is not perfect for some kinds,for example Crimson seedless grape.otherwise the ProGibb and Guomei PGRs can increase the effect if they fixed other PGRs.
