| 摘 要： | 以小麦赤霉病菌(Fusarium graminearum Schw)、辣椒疫霉病菌(Phytophthora capsici Leon.)、番茄灰霉病菌(Botrytis cirerea Pers.)、油菜菌核病菌(Sclerotinia sclerotiorum(Lib.)de Bary)、白菜黑斑病菌(Alternaria brassicae(Berk.)Sacc)、番茄叶霉病菌(Fulria fulva(cooke)Ciferri)为供试菌种,并以反枝苋(Amaranthus retroflexus)、紫花苜蓿(Medicagos sativa)、野燕麦(Avena fatua)、婆婆纳(Veronicapersica)、番茄(Lycopersicon escuientum)等5种作物种子为供试对象,分别采用生长速率法和种子萌发法,初步测试了鬼臼毒素和脱氧鬼臼毒素的抑菌和除草活性。结果表明,在供试浓度下,鬼臼毒素对油菜菌核、脱氧鬼臼毒素对辣椒疫霉活性最好,其抑制率分别为87.42%和85.7%;除草活性研究表明,鬼臼毒素对反枝苋和野燕麦根的抑制效果最强,抑制率分别为93.39%和86.28%,脱氧鬼臼毒素对婆婆纳、野燕麦和反枝苋根的抑制效果最强,抑制率分别为95.62%,89.46%,84.48%。鬼臼毒素和脱氧鬼臼毒素的抑菌和除草作用的研究为其作为一种新的植物源抑菌剂和除草剂的进一步开发利用提供了依据。

| Abstract: | Applying growth rate and seeds germination method, the antifungal activities of podophyllotoxin and deoxypodophyllotoxin were tested on Fusarium graminearum, Phytophthora capsici, Botrytis cirerea., Sclerotinia sclerotiorum, Alternaria brassicae and Fulria fulva, and the herbicidal activities of which were tested on Amaranthus retroflexus, Medicagos sativa, Avena fatua, Veronica persica and Lycopersicon escuientum. The results showed that under the tested concentration, podophyllotoxin had better inhibiting activity against Sclerotinia sclerotiorum, and podophyllotoxin had better inhibiting activity against Phy- tophthora capsici, the inhibiting rates were 87.42% and 85.7% respectively. Herbicidal activity test showed that podophyllotoxin against root growth of A.retroflexus. and Avena fatua, deoxypodophyllotoxin against root of A.retroflexus, Avena fatua and Veronica persica had the stronger inhibition effect, the inhibiting rates were 93.39% , 86.28% and 95.62%, 89.46%, 84.48 % respectively. The studies showed that podophyllotoxin and deoxypodophyllotoxin have potential to be developed as new botanical antifungal agents and herbicides. |
