| Abstract: | Ten kinds of endophytic fungus in eucalyptus were inoculated in the seedling of E.urophylla×E.grandis by applying fungus liquid,the experiment of low temperature stress was carried thirty days later.The results showed that in comparison with control group the semilethal temperature of treatment group 1,7,5,6,9,3,2 and 8 decreased by 2.71,2.28,1.98,0.77,0.61,0.61,0.26 and 0.08 ℃,respectively;the activities of POD of treatment group 1,7,10,5,8,2,6,4 increased by 35.40%,22.52%,12.11%,12.11%,10.04%,8.23%,4.04% and 0.62%,respectively;the activities of SOD of treatment group 1,3,4,5,7 and 8 increased by 36.39%,6.79%,0.06%,4.97%,12.98% and 8.25% respectively;the content of MDA of treatment 5,7,1,4 and 9 decreased by 40.40%,29.08%,28.86%,4.88% and 1.78%,respectively.The results indicated that the cold resistance of eucalyptus increased greatly by inoculating with No.1 endophytic fungus of eucalyptus. |
