风箱果( Physocarpus amurensis)为濒危种。通过对风箱果种子结实量和种子特性进行测定,结果表明:风箱果果实出种量很低,含1~2粒种子的果实比例最大,平均为3.0粒种子,且不同采种母树间种子质量差异显著( P<0.05);风箱果种子含水量、千粒种子质量和生活力分别为9.86%、1.42 g和94.44%;种子24 h达到了吸水饱和状态,种子不存在种皮透水不良的问题;不同采种母树间种子的发芽率差异不显著(P>0.05),平均发芽率较低(21.25%)且发芽缓慢;播种出苗率仅为6.22%。
風箱果( Physocarpus amurensis)為瀕危種。通過對風箱果種子結實量和種子特性進行測定,結果錶明:風箱果果實齣種量很低,含1~2粒種子的果實比例最大,平均為3.0粒種子,且不同採種母樹間種子質量差異顯著( P<0.05);風箱果種子含水量、韆粒種子質量和生活力分彆為9.86%、1.42 g和94.44%;種子24 h達到瞭吸水飽和狀態,種子不存在種皮透水不良的問題;不同採種母樹間種子的髮芽率差異不顯著(P>0.05),平均髮芽率較低(21.25%)且髮芽緩慢;播種齣苗率僅為6.22%。

Physocarpus amurensis is one of endangered plants.The experiment was conducted to measure the seed yield and seed characteristics .The fruit yield is very low, the proportion of fruit with 1-2 grains is the largest and mean seed number per fruit is 3.0.Seed weight between different mother trees is significantly difference ( P<0 .05 ) .Seed moisture content, 1 000-seed-weight and seed vitality are 9.86%, 1.42g and 94.44%, respectively.Seeds reaches the water saturation point in 24 hours without the seed non-existent the problem of poor water permeability .The seed germination rate among different the mother trees has no significant difference (P>0.05).The average germination rate is low (21.25%) with slower germination, and the seedling emergence rate is only 6.22%.
