外源GA_3和2,4-D对椪柑果实延迟采收品质的影响

在湖北省沙洋县官档镇椪柑基地,以椪柑为试材,研究外源GA3和2,4-D对椪柑果实延迟采收品质的影响,以探讨外源GA3和2,4-D对椪柑果实的效应。结果表明:椪柑果实通过外源GA3和2,4-D处理以后果实可溶性总糖、维生素C的含量增加,而可滴定酸的含量减少,延缓了果皮叶绿素的降解。与对照相比,各处理均能明显延迟果实成熟,其中喷施50mg·L-1GA3和50mg·L-12,4-D处理的效果最佳,说明在外源GA3和2,4-D处理中,此浓度处理最适于椪柑。外观品质也得到了明显的改善,果实无污染,风味浓甜,市场售价和收益显著增加。

Effect of Exogenous GA3 and 2,4-D on Kam Peng Fruits of the Delayed Harvest

Shayang County of Hubei Province in the town of stalls kam peng base to peng kom were used to study the source of GA3 and 2,4-D peng citrus fruits of the harvest quality of delay,to explore foreign GA3 and 2,4-D effect on kam peng fruit. Use of the fruit peel chlorophyll,carotenoids,total soluble sugar,acid and vitamin C to the determination;In between the different treatment by Dunca’s new rehabilitation of poor conduct analysis of variance test results showed that: kam peng fruit through foreign GA3 and 2,4-D treatment after the fruit of total soluble sugar,vitamin C content increased,while titratable acid in reducing,delaying peel chlorophyll degradation. Compared with the control,the treatment can significantly delay fruit maturity,spraying 50 mg·L-1 GA3 and 50 mg·L-1 2,4-D with the best results on outside sources GA3 and 2,4-D treatment.This concentration of dealing with the most suitable for kam peng. Appearance quality improved significantly,pollution-free fruit,sweet flavor concentration,the market price and earnings increased significantly. Kam peng research and promote tree preservation technology to stay in the same area of land on access to high-income and technology,was the urgent needs of farmers,was now kam peng industry trend of development.
