虎榛子

（以下简称P.i），对虎榛子进行了菌根合成研究。通过对接种4个月的幼苗进行菌根形态观察，以及菌根感染率、生物量的测定。

Ectomycorrhizal morphology of inoculated seedlings for 4 months was observed , and ectomycorrhizal infection rates and biomass were measured .

半阳坡虎榛子根系较半阴坡的生物童明显减少。

The root biomass on half sunny slope was obviously smaller than that of half shady slope .

结果表明，不同立地的虎榛子根系分布特征具有明显差异性；

The results indicated that there were significant differences in the root distribution characters on different sites .

虎榛子叶片气孔长度、面积和密度均呈下降趋势，降低率分别为-7.91%、-1.43%和-9.73%；

Davidiana all decreased with dropping rate of - 7.91 % , - 1.43 % and - 9.73 % respectively .

采用分层分段挖掘法，对晋西黄土高原虎榛子根系的分布特征进行了研究。

By means of dig methods from up to down , the root distribution characters of Ostryopsis davidiana were studied in the loess plateau of western Shanxi .
