不同品系福建山樱花叶功能性状研究

Leaf Functional Characteristics in Different Strains of Prunus campanulata

摘要:

为了解福建山樱花(Prunus campanulata)的叶片功能性状,对4 个品系的叶形指数、比叶面积、叶绿素含量以及叶干物质含量进行了研究。结果表明,福建山樱花不同品系间的叶功能性状都存在显著差异。叶功能性状间存在一定的相关性,叶形指数与叶干物质含量存在显著负相关(P<0.05);比叶面积与叶绿素含量存在极显著正相关(P<0.01),其与叶干物质含量呈极显著负相关(P<0.01)。经过综合评价,池边3 号品系的叶绿素含量、叶干物质含量较大,花期长,花量稠密,可推荐作为园林观赏和行道树种。

Abstract:

In order to understand the leaf functional traits in different strains of Prunus campanulata, the leaf index, specific leaf area, chlorophyll content and leaf dry matter content in four strains were studied. The results showed that there were significant differences in leaf characteristics among the four strains. Leaf index had negative correlation with leaf dry matter content (P<0.05). Specific leaf area had significant positive correlation with chlorophyll content (P<0.01) while had significant negative correlation with leaf dry matter content (P<0.01). By comprehensive evaluation, the strain of CB3 has high chlorophyll and leaf dry matter contents, long flowering and dense flowers, so that it's recommended as an ornamental and street tree species.
