摘要
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。
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.
