UV-B辐射增强对河南省夏直播花生产量及品质的影响
Effect of enhanced UV-B radiation on the quality and yield of summer sowing peanut in Henan Province
摘要
Abstract
The influence of enhanced surface ultraviolet-B( UV-B) radiation on yield and quality of peanuts( Kain-ong 49) were simulated under cropland conditions.Three UV-B radiation treatments,namely control group,enhanced by 20% and enhanced by 40%,were set up based on UV-B level in sunlight.The result showed that UV-B radiation enhancement can reduce the peanut yield significantly,which was due to the reduction of pod number as well as hundred-grain weight.The influence of UV-B radiation enhancement on peanut quality was not significant in this study.When UV-B radiation was enhanced by 20%,fat content and protein content of the peanut were 51�02%, 22�34%,respectively,and ratio of oleic acid to linoleic acid was 1�19,which was improved by 0�02 compared with the control group. When UV-B radiation was enhanced by 40%, fat content was 51�82%, protein content was 22�56%,and ratio of oleic acid to linoleic acid was 1�28,which was improved by 0�11 compared with the control group . The research result suggested that the enhanced UV-B radiation was not enough to have obvious impact on the peanut quality,which might be related to the UV-B radiation level,experiment design or peanut variety.关键词
