| 摘 要： | 对小麦株高构成因素与产量及其他性状相关性进行了研究，结果表明：小麦株高构成因素与产量及其他性状之间存在着不同程度的相关，其中，株高与倒二叶长呈极显著正相关；与其部三节长，倒二叶面积呈显著正相关，基部一节长与倒三叶长呈显著正相关，与倒三叶面积，公顷穗数呈不显著正向相关。基部二节长与基部三节长，倒三叶长，倒三叶面积呈极显著正相关，与倒二叶长呈显著正相关，基部三节长与倒二叶长呈极显著正相关。基部四节长与倒二叶宽，倒二叶面积，倒三叶宽，旗叶宽，旗叶面积呈极显著负相关，与单穗重呈显著正相关，穗茎节长与穗粒数呈显著正相关。穗长与千粒重，倒三叶面积呈不显著负相关，与其他性状均无相关或相关系数很小。

| Abstract: | In this paper the correlations between the components of the plant height and the yield and other traits in wheat were studied. The results indicated that the components of the plant height was related to the yield and other traits at different levels, of which the plant height was related positively to the length of the second leaf above at extreme significant level. The plant height was related significantly to the length of the third node below and the area of the second leaf. The length of the first node to the length of the third leaf was positively related and was positively related insignifiantly to the area of the third leaf. The length of the second node below was positively related to the length of the third node below and the length and the area of the third leaf above at extremely sigsiflocnt level, was positively related to the length of the second leaf above significantly. The length of the third node below was positively related to the length of the second leaf at extremely signifiloant level. The length of the fourth node below was positively related to the width and area of the second leaf above, the width of the third leaf above, the width and area of the flag leaf at extremely signiflcant level, was positively related to grain yield significantly. The length of the head node was positively related to the kernels perhead significantly. Spike length was nagetively related to 1 000 kernels weight, the area of the 3 leaf above in signiflcantly was not related to any other traits or was related to other traies very little. |
