摘要：采用蒸馏水浸提法收集薄壳山核桃叶及青皮化感物质,运用室内生物测定法检测其不同浓度(0.005、0.01、0.1 g·m L-1)浸提液对小麦、油菜和绿豆种子萌发和幼苗生长的影响。结果表明:薄壳山核桃叶及青皮水浸液处理对3种受体植物的种子萌发和幼苗的苗高基本上表现为"低(0.005 g·m L-1)促高(0.1 g·m L-1)抑"的双重浓度效应,个别受体植物的化感作用虽然表现不同于"低促高抑"的整体趋势,但随着浓度的增加也表现为促进作用降低或抑制作用增强的现象;对3种受体植物根长的抑制作用大于对苗高的抑制作用,而对幼苗鲜质量、干质量的影响则因受体种类的不同而不同。薄壳山核桃叶水浸液处理对3种受体植物的综合化感效应依次为:油菜>小麦>绿豆;青皮水浸液处理对3种受体植物的综合化感效应依次为:小麦>油菜>绿豆。综合3种受体植物的化感效应认为,在相同浓度下,薄壳山核桃叶水浸液处理对3种受体植物的促进作用最强,而青皮水浸液处理对3种受体植物的抑制作用最强。
In order to probe the allelopathic from leaves and husks of Carya illinoensis, the effects of different con- centrations （0. 005, 0.01, and 0. 1 g·mL^-1 ） of water extractions from leaves and husks of C. illinoensis on the seeds and plants of Triticum aestivum, Brassica napus, and Vigna radiata were studied with indoor bio-assay. The results showed that water extractions improved seed germination plant height of tested plants in low levels （0. 005 g·mL^-1）, whereas inhibited in high levels （0.1 g·mL^-1 ）. Some plants showed improved or inhibited effect with- in the scope of its concentration, but with the increase of concentration they also performed the promoting effect to reduce or inhibition enhance. The inhibitory effect of water extractions from leaves and husks of C. illinoensis on root length was higher than on shoot height for 3 crop species, but had different impacts on the fresh and dry weightof receptors due to variant species. The order of the on 3 plant species is T. aestivum 〉 V. radiata 〉 synthesis effects of water extractions from leaves of C. illinoensis B. napus. The order of the synthesis effects of water extractions from husks of C. illinoensis on 3 plant species is T. aestivum 〉 B. napus 〉 V. radiata. To synthesize the allelo- pathic effect of 3 plant species, the promoting effect of water extractions from leaves of C. lllinoensis on 3 plant spe- cies is higher, but the inhibition of water extractions from husks of C. illinoensis on 3 plant species is higher in the same concentration.
