【摘要】 对黄栌容器苗进行长期干旱和反复干旱处理，测定育苗基质含水量和苗木叶片水势及干旱条件下苗高、地径胁迫指数，结果表明基质含水量与苗木叶片水势呈正相关，在平均气温 ３０．６℃条件下反复干旱处理，黄栌容器苗存活率为５２．５％，苗高、地径胁迫指数分别为０．８３６８和０．８７８２。更多还原

【Abstract】 The container seedingr of Cotinus coggygria var. Pubescens under long-term and alternating drought were tested for moisture content of seedling medium, water potential of eding leaves and sires index of sealling height and of basal diameter. The results showed that under the condition of mean temperature of 30.6 ℃ and alternating dry treatment, there was a positive correlation between moisture content of seedling medium and water potential of seedling leans. The survival rate of container seedling was 52.5 per cent, the stres index of seedling height and basal diameter was 0.8368 and 0.8782, respectively.更多还原
