摘要:
列当属杂草对新疆地区的加工番茄、向日葵、西甜瓜等经济作物造成严重危害。为促进列当种子“自杀发芽”物质的化学合成，本研究探索了鱼腥草叶片甲醇浸提液对两种列当种子萌发的诱导效果。结果表明：鱼腥草对列当种子的萌发刺激作用表现为“低促高抑”效应。不同产地的鱼腥草对两种列当种子萌发的影响不同，广西产鱼腥草的甲醇提取物在浓度为3 570.000 μg·mL-1时，瓜列当种子的发芽率最高（65.38%）；四川产鱼腥草甲醇提取物则是在浓度为8.925 μg·mL-1时，瓜列当种子的发芽率最高（89.18%）。广西产鱼腥草在浓度为0.450 μg·mL-1时，向日葵列当种子的发芽率最高（85.39%）；四川产鱼腥草在浓度为8.925 μg·mL-1时，向日葵列当种子的发芽率最高（77.57%）。综合分析表明鱼腥草可以作为诱捕植物诱导瓜列当和向日葵列当种子“自杀式萌发”。
Abstract:
Orobanche aegyptiaca and Orobanche cernua var.cumana cause serious harm to the processing tomato,sunflower,watermelon,muskmelon and other main economic crops in Xinjiang.Methanol extracts of Houttuynia cordata leaves from Guangxi and Sichuan were used as experimental materials,to evaluated induction effect of seed germination of O.aegyptiaca and O.cernua var.cumana and to lay a foundation for the chemical synthesis of “suicide germination” substances.The results showed that the stimulating effect of methanol extract of H.cordata on the germination of seeds was "low promoting and high inhibiting".When the concentration of methanol extract of H.cordata from Sichuan was 8.925 μg·mL-1,the germination rate of seeds of O.aegyptiaca and O.cernua var.cumana were the highest,89.18% and 77.57%，respectively.When the concentration of methanol extract of H.cordata from Guangxi was 3 570.000 μg·mL-1,the germination rate of O.aegyptiaca seeds was the highest,which was 65.38%;At the concentration 0.450 μg·mL-1,the germination rate of O.cernua var.cumana seeds was the highest,which was 85.39%.In conclusion,H.cordata can be used as a trapping plant to induce suicide germination of O.aegyptiaca and O.cernua var.cumana seeds.
