GA3对轮台白杏坐果及果实品质的影响
Effects of GA3 on Fruit Setting and Fruit Quality of Luntai Amerniaca Vulgaris
摘要
Abstract
[Objective] To explore the effects of different concentrations of GA3 on Luntai Amerniaca Vulgaris fruit setting and quality and lay the foundation for the cultivation and regulation of Luntai Amerniaca Vulgaris fruit.[Method]Taking Luntai Amerniaca Vulgaris as the research object, 40 mg/L, 90 mg/L and 140 mg/L concentrations of GA3 were sprayed at full flowering stage and 20 d after anthesis.The fruit setting rate was analyzed 20 d after flowering, fruit vertical diameter, transverse diameter, lateral diameter and single fruit weight were measured regularly, the fruit quality was determined after the fruit ripening.[Result]GA3 treatment significantly increased the fruit setting rate, and the fruit vertical, horizontal and lateral size effectively, but the quality of the fruit has been reduced.90 mg/L GA3 significantly increased the fruit set, an increase of 117.32% compared to the CK.After the treatment of 40 mg/L and 90 mg/L GA3, the effect of fruit enlargement was positively correlated with the concentration of GA3.When the concentration reached 140 mg/L, the phenomenon of fruit enlargement was not obvious.[Conclusion]The 90mg/L concentration of GA3 could effectively improve the yield of fruit, which could be used to control the growth and development of Luntai Amerniaca Vulgaris.关键词
