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。
以引種造林的樟子鬆為對象，對不同植株的果實和種子性狀進行觀測與分析，結果錶明：不同植株的毬果大小、果鱗鱗臍位置與突起程度、榦燥後毬果開裂程度、種翅特徵、種皮顏色、種子成熟度、齣種率均存在差異或顯著差異；株間種子重量差異極顯著（P ＜0．01），主要由箇體遺傳差異所造成。
이인충조림적장자송위대상，대불동식주적과실화충자성상진행관측여분석，결과표명：불동식주적구과대소、과린린제위치여돌기정도、간조후구과개렬정도、충시특정、충피안색、충자성숙도、출충솔균존재차이혹현저차이；주간충자중량차이겁현저（P ＜0．01），주요유개체유전차이소조성。
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 de-gree 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 indi-vidual genetic differences .
