摘要:
 以3年生水曲柳、胡桃楸、黄蘖为研究对象，对幼树不同部位火烧（叶片被火烧T1、枝被火烧T2、茎被火烧T3）后叶片细胞膜相对透性、MDA含量、SOD活性、POD活性和Pro含量的变化进行研究。结果表明：水曲柳、胡桃楸、黄蘖直接火害叶相对电导率和MDA含量变化规律一致，显著高于对照，其中水曲柳叶片细胞膜破坏程度和膜脂过氧化程度最大；3种幼树直接火害叶SOD、POD活性和Pro含量都显著提高，其中水曲柳SOD活性和Pro含量提高最多。火烧后3种幼树新生叶相对电导率除胡桃楸的茎火烧处理显著提高外，其他都与对照差异不显著；茎火烧处理的胡桃楸MDA含量显著提高，水曲柳的叶和枝火烧处理、黄蘖的枝和茎火烧处理显著降低；SOD、POD活性和Pro含量因树种和火烧处理的不同而不同程度的提高。对一些树种进行适当的火烧会提高幼树对火的适应能力和抵抗能力，在计划火烧和提高树木的抗火性方面具有积极的意义。
Abstract:
 Using potted 3-year-old saplings of three tree species,Fraxinus mandshurica,Juglans mandshurica and Phelodondrom amurense as objects，the effects of burning to different organs (leaf burn,T1; branch burn,T2; stem burn,T3) on the cell membrane permeability and protective enzyme (SOD,and POD) activities,as well as the contents of MDA and proline were examined.The results showed that in T1,the variation patterns of relative electrical conductivity and MDA contents were the same among the three species,and higher than those of the control.F.mandshurica demonstrated the serious damage on cell membrane and membrane peroxidation.SOD activity,POD activity and proline contents in the leaves of three tree species significantly increased compared to the control,in which the increases in F.mandshurica was the most.All relative electrical conductivity of young leaves of the three tree species,except for J.mandshurica whose relative electrical conductivity significantly increased in T3,there was no significant changes in three fire treatments.The MDA content significantly increased in J.mandshurica in T3,and significantly decreased in F.mandshurica in T1 and T2,and in P.amrense in T2 and T3.SOD and POD activities and proline contents in young leaves of three saplings showed different increases with different species and treatments.Proper burning of some tree species will improve the adaptability and resistance to fire of young trees.The results presented positive significance in improving fire resistance of the trees with intentional burning.
