乙烯利处理对菠萝蜜果实催熟的影响

Activity test and sugarcane injury test of three herbicides combination for sugarcane in greenhouse

摘要: 以干包类型菠萝蜜“75”株系果实为试材，研究0、500、1 000、1 500、2 000 mg/L 乙烯利（CEPA）处理对菠萝蜜果实成熟的影响。结果表明院乙烯利处理加速了菠萝蜜果实中淀粉、纤维素和原果胶的降解，促进了菠萝蜜果实总糖、还原糖、蔗糖含量的升高，提早了有机酸和Vc 含量高峰的出现，显著地降低了菠萝蜜果实在贮藏前期的蛋白质含量，并提高了贮藏后期蛋白质和可溶性果胶的含量，其中，1 000 mg/L 乙烯利处理效果最好。

Abstract: Hexazinone diuron and ametryn were mixed at a set proportion, activity and security experiments were conducted through plot culture in greenhouse. Results showed that activity of the mixed herbicide combination, significantly improved in sugarcane field on Echinochloa colonum (L.) Link. Compared with the ametryn, safety of sugarcane arieties was Guitang No. 28>Yuetang No.128>ROC22. Combination of hexazinone, diuron and ametryn was safe than ametryn in the test.
