摘　　要：通过对玉米植株高度、叶片长宽的相关分析可以看出,在所考查的指标中,末节高度、穗位能更好地评价玉米自交系的生长特性;穗上长度和穗位分别与叶片的长度和宽度普遍呈极显著相关,这四个性状表明了玉米生长发育阶段的差异.The relativity of plant height with leaf length and leaf breadth of corn was analyzed.The results showed that the last node height and position of spike were better to appraise the growth feature of corn inbred strain in all indexes.Spike length and position were correlated respectively with leaf length and breadth.These four characters indicated the difference of corn growth phase.
