| 摘 要： | 以不同粒型的花生品种为材料，研究衰老过程中叶片的生理特性及产量性状。结果表明：后期叶片NR、PAL的活性呈下降趋势，但大粒型品种较小粒型品种下降速度慢；开花50d以后，大粒型品种AsA-POD的变化呈抛物线下降（Y=-0．0492X^2＋5．5791X-146．82）；小粒型品种呈直线下降（Y=-0．553X＋39．302）。MDA含量在开花后60—65d迅速上升，至成熟期，大粒型品种MDA含量较小粒型品种降低44．9％，百仁重、百果重平均分别增加46．8％、61．4％，产量提高33．2％。 |

| Abstract: | With different seed-types of peanuts,some physiological traits and yield properties were researched in the course of senescence.The results showed that NR and PAL activities in leaves presented a descending trend in later stage,but the descent speeds for bigger seed types were slower than that of smaller types.The changes of AsA-POD activity decreased on a parabola trend for the bigger types:Y=-0.0492X~2+5.5791X-146.82;and on a linear trend for the smaller ones:Y=-0.553X+39.302.The MDA content ascend quickly during 60-65 days after anthesis for both types.Compared with the smaller species,the MDA content of bigger ones were reduced by 44.9% in mature stage.Finally the 100 seed weight and 100 nut weight were increased by 46.8% and 61.4% respectively.The yield were increased by 33.2%. |
