摘要: 采用正交设计,研究了B5培养基蔗糖和大量元素、微量元素及有机组分含量调节对沙打旺组培根生长的影响;并采用玻璃皿滤纸培养法,进行了培养滤液对萝卜和小麦幼苗生长干扰作用的研究.结果表明,培养滤液的生长干扰作用实际是化感效应;同时,营养胁迫是引发沙打旺化感效应的重要原因.有望为探明沙打旺化感作用营养胁迫机理提供初步的科学依据.

关键词: 沙打旺, 组培根, 培养滤液, 化感作用

Abstract: By using orthogonal design,this paper investigated the growth of cultured prairie milk vetch (Astragalus adsurgens) root on the B5 medium with different contents of sucrose,macro-and microelements and organic supplements,and adopting the method of filter paper-culture in Petri-dish,studied the effects of A.adsurgens culture filtrate on the seedling growth of radish (Raphanus sativus) and wheat (Triticum aestivum).The results showed that the effect of A.adsurgens culture filtrate on R.sativus and T.aestivum seedling growth was of allelopathic,and nutritional stress might be the important cause of A.adsurgens allelopathy.

Key words: Astragalus adsurgens, Cultured root, Culture filtrate, Allelopathy
