摘　　要：为了探究亚麻荠根系分泌物对胡麻和杂草藜的化感作用,采用水培法观察了亚麻荠根系分泌物对胡麻和藜种子萌发与幼苗生长的影响。结果表明,亚麻荠根系分泌物对胡麻和藜种子的萌发具有抑制作用,且抑制作用随着处理浓度的增加而增强。亚麻荠根系分泌物对胡麻根长、根鲜重、苗鲜重具有抑制作用,在低处理浓度时对胡麻苗高具有促进作用,在中、高处理浓度时抑制作用较小;对杂草藜幼苗生长具有抑制作用,但抑制作用较小。综合分析,亚麻荠根系分泌物在低处理浓度时对胡麻生长的抑制作用小于对藜的抑制作用,在中、高处理浓度时大于对藜的抑制作用。In order to explore the allelopathic effects of Camelina sativa root exudates on oil flax and quinoa,this research studied the effects of Camelina sativa root exudates on seed germination and seedling growth of oil flax and quinoa using hydroponics in the laboratory.The results showed that the Camelina sativa root exudates had inhibitory effects on seed germination of oil flax and quinoa,and the inhibition increased with the increase of treatment concentration.Root exudates of Camelina sativa inhibited the root length,root fresh weight and seedling fresh weight of oil flax and promoted seedling height of oil flax at low concentration treatment,but it showed little inhibitory effect at medium and high concentration treatments.It inhibited the growth of quinoa seedling,but the inhibition effect was small.Comprehensive analysis showed that the root exudates of Camelina sativa had less inhibitory effect on the growth of quinoa than that on oil flax at low concentration treatment,and more inhibitory effect on the growth of quinoa than that on oil flax was detected at medium and high concentration treatments.
