摘　　要：通过分析多种丁香叶片的叶柄长度,叶厚度及各叶形指数,探究丁香属((Syringa))植物叶片与叶柄之间生长关系的物种差异。结果表明,西宁市19种丁香叶面积、叶鲜重和叶干重与柄长柄径之间具有异速生长关系,且异速增长指数均大于1 (p <0.05),而丁香叶面积、叶片质量与叶柄质量之间不存在明显异速生长关系,分析19种丁香物种的异速生长指数,发现不同丁香物种的异速生长指数分布不同。To explore the species differences in the growth relationship of clove(Syringa),the petiole length,leaf thickness and leaf shape index of various clove leaves.The results showed that the 19 species of lilac leaf area,leaf fresh weight and leaf dry weight had their stem diameter in Xining,and the allometric growth index was greater than 1(p<0.05),while there was no obvious allometric relationship between clove leaf area,leaf mass and petiole mass.Finally,the allometric index of 19 clove species showed that the allometric index distribution was different in different clove species.
