摘要
以引种造林的樟子松为对象,对不同植株的果实和种子性状进行观测与分析,结果表明:不同植株的球果大小、果鳞鳞脐位置与突起程度、干燥后球果开裂程度、种翅特征、种皮颜色、种子成熟度、出种率均存在差异或显著差异;株间种子重量差异极显著(P<0.01),主要由个体遗传差异所造成。
Observation and analysis of seed character among Pinus sylvestnis var.mongolica Litv.showed that there was difference or significant difference among cone size in different plants,umbo position and process degree of cone scale,cone cracking degree after drying,seed wing characteristic,seed coat color,seed maturity and seed percentage.There was significant difference between seed weight(P 0.01),it was caused by individual genetic differences.
