| 摘 要： | 进行了油松,华北落叶松苗木盆栽试验,在土壤由湿（适宜）到严重干旱的变化过程中,测定了苗木的凋萎系数,叶片水势,根系活力,蒸腾强度,观察了苗木生长的外观反应。对两树种的抗旱性能进行了综合评价,结论是：油松的抗旱性能优于华北落叶松。

| Abstract: | Drought resistance of P.tabulaeformis and L.principis-rupprechtii was studied by pot-planting.As the variations of soil water content from availableness to serious defficiency,wilting coefficient ,leaf water potential,root activity and transpiration rate were measured,and appearance characteristics of seedling growth were also observed.The results showed drought resistance of P.tabulaeformis was better than that of L.principis-rupprechtii . |

| Keywords: | P.tabulaeformis L.principis-rupprechtii drought resistance wilting coefficient. |
