文冠果在新疆石河子垦区的引种适应性研究

Resesrch on Adaptability of Introduced Xanthoceras sorbifolia Bunge in Xinjiang Shihezi Region

试验以山西交城文冠果种子为材料,用赤霉素、萘乙酸、2,4-D、6-BA、吲哚丁酸对文冠果种子进行了处理,并对其生理生化指标——POD、PPO、SOD和CAT酶活性进行了测定与分析,并结合对其物候期进行了观察,结果表明:1)不同激素处理对SOD影响:GA3最强,6-BA次之,2,4-D最弱;2)不同激素、不同浓度处理对苗子POD、PPO的活性影响不明显;3)不同激素、不同浓度处理能极显著地影响SOD酶活性,不同激素处理也能极显著地影响CAT酶活性,对提高适应性有积极意义;4)文冠果的物候期表现与山西交城县基本相似,从气候条件考虑引种是可能的。

This Experiment treated Shanxi ＂Jiaocheng＂ Xanthoceras sorbifolia Bunge＇s seeds with different hormones（GA3,NAA, 2,4-D, 6-BA and IAA）, measured and analyzed its psychological indexes such as enzyme activity of POD ,PPO,SOD and CAT. The results showed：（1） GA3had the most important influence on SOD （the main protective enzyme）of the seed, next is 6-BA,the weakest one is 2,4-D＇（2） Different hormones had little influence on POD, PPO activity of the seed;（3） Different hormones with different concentrations had obvious influence on SOD of the seed; Different hormones also had obvious influence on CAT of the seed;（4） phenology of Xanthoceras sorbifolia in shihezi region was similar to that in Shanxi jiaocheng,so the introduced Xanthoceras sorbifolia in Shihezi is feasible according to the climate.
