摘要

为了鉴别8个油松(Pinus tabulaeformis Carr.)种源的抗旱性，以其3年生幼苗为研究对象，进行了控水条件下的盆栽实验(T1:土壤含水量为25%∼29%;T

:土壤含水量为19%∼22%;T

:土壤含水量为12%∼15%);测定了其净光合速率(Pn)、蒸腾速率(Tr)、超氧化物歧化酶(SOD)和过氧化物酶(POD)等生理生化指标，并应用Fuzzy隶属函数对它们的抗旱性进行了综合评价。结果表明，在T

条件下，8个种源的Pn无显著差异(P>0.05);种源2的Tr显著高于种源1，3，5(P

0.05);种源5的水分利用效率(WUE)显著高于种源2，3，4，6，7，8(P

0.05)。与T

条件相比，在T

条件下，各种源的SOD活性均有所增高，多数种源的POD活性均有所增高;种源7，8膜脂过氧化程度较小，而种源1，3，4，5膜脂过氧化程度较大。8个种源的抗旱性依次为:种源8>种源6>种源1>种源5>种源4>种源3>种源7>种源2>。

Abstract

To test the drought resistance of eight provenances(PRs) of Chinese pine(Panus tabulaef ormas Carr.)

a soil water treatment experiment with water gradients(T1:w ater content was 25%-29%

T2:19%-22 %

and T3:12%-15%)for 120 potted 3-year-old seedlings was conducted. Some physiological and biochemical indexes such as net photosynthetic rate(Pn)

transpiration rate(Tr)

superoxide dismutase (SOD)

activity

and peroxidase(POD) activity were measured and analyzed. Results showed that no significant difference was observed in Pn，among the provenances ander T3>0.05). How ever

PRz had significantly higher Tr than PR1，PR3

and PR5 and PRs5 had significantly higher water use efficiency(WUE) than PR2

PR3，PR4

PR6，PR7

and PR8(P<0.05) under T2.In comparison with those under T2

the SOD activity of all provenances and the POD activity of most provenances reached a higher level under T3.PR7 and PR8 had weaker membrane lipid peroxidation and PR1

PR3

PR4

and PR5 had stronger membrane lipid perm oxidation. In terms of the drought resistance of the provenances

the treatments had the following order of PR8> PR6> PR1>PR5> PR 4>PR3≅PR7>PR2.
