桂花叶及果实形态性状变异研究

以叶面积、叶长等叶片形态性状和果长、果宽等果实形态性状为指标,研究了桂花叶片和果实形态性状在单株水平上的遗传变异规律。结果表明,桂花叶片和果实等形态性状在单株水平上存在着丰富的遗传变异,且叶片形态性状与果实形态性状由各自独立的遗传基因控制,并受到高等程度的遗传控制,遗传潜力较大。

Morphological variation of leaf and fruit of Osmanthus fragrans

Using the morphological traits such as leaf area,leaf length,fruit length and fruit width as indices,the genetic variation of morphological traits of leaf and fruit of Osmanthus fragrans were explored at the individual level. The results showed that,the morphological traits of leaf and fruit possessed abundant variation at the individual level,and the leaf and fruit morphological traits were controlled by independent genes,respectively,implying high genetic control of the traits.
