对壳斗科濒危种越南青冈种子贮存特性、种子萌发和幼苗建成条件进行了研究,结果表明,越南青冈种子易萌发但难出苗,壳斗脱落的种子4℃贮藏60d后有85.6%发芽,壳斗完整的则有50%可贮藏至翌年春。播种时坚果侧立放置有利于出苗,出苗时空气相对湿度要保持在90%以上,否则幼茎很快枯死,难以成苗,直至幼苗真叶完全展开转绿才可逐步降低空气相对湿度。
The storage property,seed germination characteristics and seedling establishment conditions of the endangered oak Quercus austrocochinchinensis were studied.The results showed that seeds of Quercus austrocochinchinensis were easy to germinate but hard to successfully establish seedlings.Acorns without cupules have 85.6% germination rate even after 60 dstorage at 4℃,while the acorns with cupules can be stored until to the next February with only 50% germination rate.It is beneficial for seedling establishment to sow the acorns side standup.The key point for seedling establishment is to keep the relative air humidity above 90%,otherwise the new emerged stem will dry out.The air humidity can be gradually decreased after the true leaf fully expanded.
