| 摘 要： | 采用生物测定的方法,研究了伊贝母(Fritilla riapallidiflora Schvek)根系分泌物成分中的1,3,5-三烯丙基-1,3,5-三嗪-2,4,6(1H,3H,5H)三酮、酚酸和二者的混合液对伊贝母幼苗的影响。结果表明,伊贝母根系分泌物成分对伊贝母幼苗体内的保护酶SOD起到抑制作用,但对POD、CAT的活性既有抑制作用亦有促进作用。对幼苗体内MDA及叶绿素含量有促进作用。 |
| 关 键 词： | 伊贝母 根系分泌物 保护酶 自毒作用 |

| Abstract: | Secrete exudates which contain root-specific metabolites in plant roots have critical impacts on the growth of the plant itself.Changes of POD,CAT,SOD activities and the content of MDA and chlorophyll were used to assess autotoxicity of root exudates from Fritillaria pallidiflora Schvek in this paper.The results indicated that the root exudates inhibited the activity of SOD but had not obvious effects on POD and CAT,while had promoted effects on the content of MDA and chlorophyll. |
| Keywords: | Fritillaria pallidiflora Schvek Root exudates Protective enzyme Autotoxicity |
