Xinjiang is the largest national grape acreage provinces, with the production of high quality grapes unique environmental conditions of soil and climate, the production base of high-quality green grapes. The world-renowned ancient seedless white grapes. Seedless grapes eat up a good flavor, has become a trend of the development of table grapes, seedless grapes with good market prospects. The purpose of this study was to seedless grape producers to provide a key technology to produce high quality and efficient cultivation of seedless grapes, to provide guidance to the healthy development of seedless grapes for the plant growth regulator, plant growth regulator in non-nuclear grape production applications, more scientific and more reasonable, seedless grapes produce commodity rate to be greatly increased. Each species can be expected to obtain the best effect, thereby enhancing each of seedless grapes commodity rate purposes. This study for Xinjiang Shihezi University College of Agriculture Experiment Station in recent years, new developments in several excellent varieties of seedless grapes: seedless purple, Centennial Seedless, Crimson Seedless, Frey seedless, excellent seedless The respectively gibberellin, BR topiramate efficiency Long, Kagome, Keebler, brassica, China Everbright fruit ,6-BA and other plants growth swap and according to the type of plant growth regulator suitable for each of the varieties of seedless grapes , the period and the number of concentration as well as the use of different concentration ratio, frequency of use field trial processing program application effect. Through research, Xinjiang who planted five varieties of seedless grapes suitable plant growth regulator type and proportion, concentration and period and frequency. The main results are as follows: 1 seedless grapes by GA3 and other plant growth regulator treatment, change the fruit endogenous hormone levels so as to promote fruit growth and development, to increase berry purpose of increasing production. Different plant growth regulators and different proportions of the different effects of the same varieties of seedless grapes; ratio of the same plant growth regulators, and the effect is not the same for the same varieties of seedless grapes, grapes increases agent market promotion not blindly use, production, or is likely to cause large losses will, only through the promotion of small test to a large area. 2, the experimental design of different plant growth regulators and the ratio of seedless purple grapes, Centennial Seedless, Crimson Seedless, Frey seedless, excellent seedless could be used to improve the quality of its appearance; positive role in promoting its intrinsic quality also have a negative impact. Comprehensive analysis of seedless purple grapes, handle the 4,8,11 better, that spend with 75mmg / 1 GA the flowering with l00mg / 1 GA, flowers with 120mg / l gibberellin and joined with 100-150mmg / 1 Keebler 30mg / 1 Brassinolide for spend, spend after Kagome with 0.71.m1 / 1 or acceded to 30mg / 1 Brassinolide for 100mg / 1 6-BA can better improve the fruit quality of seedless purple grapes, to promote the use of production; Centennial Seedless grapes, processing 5,8 and overall performance are good, and that only after flowering with 40mg / 1 GA 50mg / 1 6-BA or 0.71m1 / 1 Kagome can improve the Centennial Seedless grape fruit quality, and promote the use of production; of Crimson Seedless grapes, processing 4 is better, that is, only after flowering with gibberellin 50 mg / 1 15 mg / 1 Brassinolide for significant improvement in fruit quality of Crimson Seedless grapes, can promote the use of production; Fresno seedless grapes, processing 4,11 effect is better, the GA 40mg / 1 before that spent, flowers with 50mg / 1 gibberellin and added 15mg / 1 Brassinolide for; flowers before use 50mg / 1 Keebler, flowers of Kagome 0.35m1 / 1 and added 15mg / 1 Brassinolide for 50mg / 1 6-BA can better improve fruit quality of the Frey seedless grapes, production application; 3,11 better, before that spent 30mg / 1 GA, flowers with 30mg / 1 GA3 added Keebler 40mg / 1; excellent seedless grapes, processing or flowers before 40mg / 1 Keebler, after flowering, if the United 0.35m1 / 1 and add 15mmg / 1 Brassinolide for and 50mg / l 6-BA can better improve superior seedless grapes fruit quality, promote the use of production . Dealt with as part of the test design is popular by the market in recent years, some seedless grapes swelling can promote plant growth regulator direct design or processing complex design, such as Keebler, Kagome. From the test results, these plant growth regulators used alone better of some varieties of effects, such as Centennial Seedless, and the effect is worse on some varieties such as Crimson Seedless. These plant growth regulating agent and other plant growth regulator compound can increase the effect of single use.
