套袋对生长期辣椒果实VC含量的影响

Effect of Bagging on VC Content in the Growth Period of Pepper Fruits

为了更好地进行辣椒无公害栽培,了解套袋对果实VC含量的影响,以cv.B54辣椒为试材,采用黄色透气纸袋对花后25d后的辣椒进行套袋处理,以相同条件下的不套袋辣椒作为对照,研究生长期套袋对辣椒果实VC含量的影响。结果表明:对不同成熟阶段的辣椒果实进行套袋处理,果实中的VC含量均下降,其中绿果期和红果期VC含量下降较为明显,转色期下降较少;通过对果实整个生长期套袋发现,无论对照还是处理,随着辣椒果实的不断成熟,果实中的VC含量均表现为先增高后降低的趋势,且套袋果实中VC的含量始终低于对照。这些结论表明套袋对于辣椒果实VC成分的积累有着一定的负效应。

In order to make pollution-free cultivation of pepper and understand the effect of bagging on the VC content of fruit,cv.B54 pepper was used as the material,and the pepper was bagged with the yellow paper bag for 25 days after flowering,no bagging fruits were under the same conditions as control（CK）.VC content was detected.The results showed that VC content of bagging fruits was obviously decreasing during green fruit stage and red fruit stage,it was decreasing relatively slightly during turning color period;Bagging was done in whole growing period of pepper fruit,whether bagged fruits or not,VC content of fruits was increased at first and decreased subsequently,however,VC content of bagging fruit was always lower than the control.These conclusions indicated that bagging had a negative effect on VC accumulation of fruit in pepper.
