马尾松无性系种子园结实量与生长性状的相关分析

摘要

通过对马尾松无性系种子园进行调查分析，结果表明：马尾松种子园无性系间开花结实与生长性状存在不同程度的显著、极显著相关，分枝角度与开花结实存在极显著的负相关，生长性状间也存在不同程度的相关性。因此，在选择优良无性系建园时，应当考虑选择速生丰产稳产的无性系。%Clonal Seed Orchard of Pinus massoniana was analyzed .It shows that flowering & fruiting of seed orchard of Pinus massoniana have significant & very significant correlations with various degrees ;branching angle& flower-ing and fruiting have significant negative correlation ;growth traits also have different degrees of relevance .Fast-growing ,high-yielding & stable clones should be selected while selecting superior clones to build gardens .
