在田间试验条件下,系统研究了花生新品种吉花3号和其亲本四粒红农艺性状、衰老特性及产量性状的差异。结果表明,新品种吉花3号明显改善了植株性状,叶面积指数显著提高,且保持较高叶面积指数和叶绿素含量的时间较长;功能叶片的SOD、POD酶活性和脯氨酸含量明显提高,MDA含量明显降低。吉花3号的单株生产力较高,荚果增产32.87%,经济系数提高了0.12。吉花3号在农艺性状、抗早衰特性及丰产性上明显优于亲本,生产中可作为四粒红的替代种植品种。
Under field conditions, the agronomic traits, senescence characteristics and yield traits of the new peanut variety Jihua No.3 and its parents were systematically studied. The results showed that the new variety Jihua 3 significantly improved the plant traits, the leaf area index increased significantly, and the retention of higher leaf area index and chlorophyll content took longer. The activities of SOD, POD and proline in functional leaves were significantly increased Increase, MDA content decreased significantly. The high per plant productivity of Jihua No.3 increased the yield of pod by 32.87% and the economic coefficient by 0.12. Jihua No.3 in agronomic traits, anti-premature aging characteristics and high yield significantly better than the parent, the production can be used as a substitute for four red varieties.
