| 摘 要： | 花生一级侧枝发育具有不均衡性。第一、二对侧枝出现早，伸长快，其他一级侧枝出现晚，伸长慢。86036－26－1第一、二对侧枝发育相对较早，而其他一级侧枝发育较晚；海花1号和豫花1号第一、二对发育相对较晚，而其他一级发育较快；豫花7号和鲁花9号居中。海花1号一级侧枝及第一对侧枝的二级侧枝数最多，86036－26－1的一级侧枝数及第一对侧枝的二级侧枝数量少。在花针期之前第一对侧枝的伸长与主茎基本同步；花针期之后，第一对侧枝伸长速度超过主茎。86036－26－1的一级侧枝长及株高居首位。86036－26－1第一、二对侧枝饱果率，产量居第一，豫花7号居第二。海花1号虽然荚果数较多，但第一、二对侧枝孢果率较低，产量也较低；鲁花9号居中。

| Abstract: | The lateral branches of first order of peanut developed in an unbalanced.The first and second pair of lateral branches not only emerged early but extended rapidly also.Other lateral branches of first order not only emerged late but extended slowly also.By comparison,the first and second pair of lateral branches of 86036-26-1 developed earliest,but other lateral branches of it developed latest;the first and second pair of lateral branches of Haihua No.1 and Yuhua No.1 developed latest,but other branches of them developed most rapidly;and that of Yuhua No.7 and Luhua No.9 were middle rate.The number of lateral branches of first order and the number of secondary branches of the first pair of branches of Haihua No.1 were most,but that of 86036-26-1 were least.Before the stage of anthesis and penetration of peg into soil,the first pair of lateral branches extended almost in the same rate with the main stem;but after the stage,the first pair of lateral branches extended more rapidly than the main stem.The length of the first pair of lateral branches and the main stem of 86036-26-1 were longest,and then were that of Yuhua No.7.Although Haihua No.1 had the most number of shale,the ratio of plump fruit of the first and second lateral branches were lower,so its yield was lower,and that of Luhua No.9 were in the middle. |
