不同居群条叶旋覆花植株形态、光合特性及化学成分分析

Analysis on morphological characteristics,photosynthetic characteristics and chemical constituents of Inula lineariifolia from different populations

以12个居群条叶旋覆花为研究对象,测定不同居群植株形态特征值、光合参数及化学成分含量,为条叶旋覆花种质资源评价提供理论依据。结果表明,不同居群条叶旋覆花具有较为丰富的形态多样性,植株形态特征值、光合参数及化学成分含量均存在显著性差异,且植株形态特征值与净光合速率均呈现正相关性。12个居群经聚类分析分为3大类,江苏盱眙、安徽凤阳与安徽明光3个居群聚为一大类,这3个居群叶型相对狭长,叶片数与花头数较多,光合性能强,化学成分含量高,可作为优良种质资源加以选择利用。

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics,photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity,there were significant differences of morphological characteristics,photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and Pn.Twelve populations were divided into three-type. The three populations of Xuyi,Mingguang and Fengyang were of narrower-longer leaf,bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.
