中文摘要:在大田条件下,研究了模拟地表UV-B辐射增强对花生(开农49号)的产量及品质的影响.UV-B辐射设3个水平,即对照、增强20%和增强40%.结果表明:UV-B辐射增强能显著降低花生产量,产量下降的原因主要是由单位面积产量、株荚果数、百仁重减少造成的;花生品质受UV-B影响较为复杂,UV-B增强20%时,花生脂肪质量分数为51.02%,蛋白质质量分数为22.34%,油酸/亚油酸质量比为1.19,较对照组提高了0.02;UV-B增强40%时,花生脂肪质量分数为51.82%,蛋白质质量分数为22.56%,油酸/亚油酸质量比为1.28,较对照组提高了0.11.研究认为,UV-B辐射增强,不足以对花生的品质产生显著影响,这可能与设定的UV-B辐射强度、试验设计方案及花生的品种有关.

Effect of enhanced UV-B radiation on the quality and yield of summer sowing peanut in Henan Province
Abstract:The influence of enhanced surface ultraviolet-B(UV-B) radiation on yield and quality of peanuts(Kainong 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.
