| 摘 要： | 采用GC-MS测定损伤冷蒿VOCs的主要成分,并通过生物测定的方法研究损伤冷蒿VOCs对牧草幼苗根系生长发育的影响。结果表明:损伤冷蒿释放30种VOCs,包含萜烯类、醇类、酯类、醛类和酮类等5类化合物,其中相对含量高于1%的化合物共占VOCs总量的97.37%,桉树脑含量最高(22.43%)。损伤冷蒿释放的VOCs极显著(P0.01)的抑制草木樨、苏丹草、披碱草和冰草幼根的伸长,以及苏丹草侧根与冰草须根的发育,抑制率分别为51.55%、55.34%、37.57%、48.68%、93.04%和25.00%;同时也极显著抑制4种牧草幼根生物量的积累(P0.01)。损伤冷蒿VOCs影响牧草根部中柱组织结构的分化,使草木樨中柱内木质部、韧皮部与形成层不能正常分化;苏丹草、披碱草和冰草的凯氏带发育不完整。由此可见,损伤冷蒿VOCs对牧草根系生长发育具有明显的抑制作用。 |

| Abstract: | In plant-plant interactions,VOCs,as pheromones,can facilitate defense capability of neighboring plants of the same or different species.Plant VOCs can also inhibit seed germination and seedling growth of other plants in the community through allelopathic effects,so the competitiveness and population growth of the VOC emitters are strengthened.The extract of Artemisia frigida Willd.significantly inhibits the seed germination and seedling growth of pasture plants.The similar effects have also been found to re... |
