青檀

在水培条件下，本文探讨了NaCl胁迫对青檀种子发芽率、叶气体交换和苗木生长的影响。

Effects of NaCl on seed germination , leaf gas exchange and seedling growth were investigated .

根系活力也如此，总体而言，S3、S4和S5处理下青檀幼苗的根系活力显著低于CK。

Root activity of each treatment fluctuated as stress time progressed , and generally speaking , root activities of S3 , S4 and S5 were highly significantly lower than that of CK .

青檀是乔木层优势树种之一，其重要值达66%。

Pteroceltis tatarinowii , one of dominant species of arborous layer had important value ( 66 % ) .

黄连木群落、栓皮栎-黄连木群落主要分布在相对较为稳定的生境中，而以青檀为优势种的群落多位于干扰频繁的地形单元上。

Pistacia chinensis community and Q. variabilis community mainly distributed on relatively stable habitats while P. tatarinowii community on frequently interference habitats .
