The Effects Of GA₃ On The Growth Of Strawberry

Strawberries is a kind of fruit which has benefits as follows, faster growing ,maturity listed early, small plants , easy breeding, management convenience, processing easily, easily regulate the fruit trees, Generally it is setted in autumn, and the fruits can be put into the market the next June.Especially in recent years to grow strawberries, semi-cultivation techniques to the development. So that the period of maturity greatly advance. From November until June strawberries have fruit listed all the time.As a low season fruit supply treasures considerable economic benefits. Because strawberries has short production cycle, low cost, and suit for the protection, it is becoming a kind of fastest-growing new industries in the hoticulture.Darselect is nurtured in 1995 in French as a new kind of variety.lt is introduced in 1997 to the city of Baoding of Hebei province and the city of Dandong of Liaoning Province which are as our country's largest mainly -producing areas of strawberry .At the same time cultivation tests are done. The varieties are early varieties, seedlings brawny, adaptability and has disease-resistant ability. The fruit are the standard red, scarlet fruit face a luster, flesh-red, has a close texture, a distinctive flavor and can be stored for a long time. Since its introduced to the southwest region ,this cultivation has shown good adaptation.The material is Darselect, and use a cultivation method with combination of field and greenhouse .The material are handled with different concentrate GA3. There are seven different levels, 0 (CK), 5, 10, 15, 20, 25, 30ppm. At random processing methods configuration. Each level of Gibberellin 20 plants as a repeat, a total of three repeat in which 10 plants growing trend generally consistent observation. To deal with the number of 1st and 2nd. Processing period for seven days after flower bud Koupeng food warming period. During regular measurements of the density of growth and results indicators. Stage stat and data processing using software Fangcha analysis, linear regression analysis for the species used in promoting cultivation, processing Gibberellin best concentration and best address the frequency with a view to promoting cultivation of the species in the southwestern areas strawberries provide scientific basis. Test results are as...
