火力楠种子园不同家系种子相关性状研究

摘要

Correlated characters of the seeds from 19 families of Michelin macclurei were studied. The results showed that there were great differences in seed characters among seeds of different families; extremely significant differences were found in seed length-width ratio and 1000-grain weight; correlation analysis showed that nonlinear law was observed between any two of the characters;2 families were selected as superior families for their high germination rate of seeds.%对火力楠种子园19个家系种子相关性状研究的结果表明：不同家系种子在各个测定指标的表现上差异较大；种子形态和质量性状差异均达到极显著水平；两两性状间相关性分析呈不规律的非线性关系。以发芽率为指标选出2个种子品质优良的家系。
