摘要:

百香果在生长过程中极易受到炭疽病的侵害,有效防止百香果炭疽病的爆发是当前种植过程中亟需解决的一项难题。本研究评估6种中草药提取物对百香果炭疽病病原菌的抑制效果。通过标准提取制备中草药粗提液,并采用平板培养法,在不同浓度(10、20、30、40、50 mg/mL)下检测其对病原菌菌丝生长的抑制作用。结果显示,中草药提取物浓度为10 mg/mL时,丁香提取物对百香果炭疽病菌的抑制作用最强,抑菌率高达100%;其次为川芎、当归、高良姜和黄芩提取物;百部提取物的抑菌率仅有30%。当中草药提取物浓度为50 mg/mL时,丁香和当归提取物的抑菌率均为100%,川芎和高良姜提取物的抑菌率均在90%以上,黄芩和百部提取物的抑菌率分别为84.43%、78.10%。综合来看,6种中草药的提取物对百香果炭疽病菌的抑制效果各不相同,其中丁香提取物抑制作用最为显著,在10、20、30、40、50 mg/mL下的抑菌率均为100%,显示出其在防治百香果主要病害方面具有巨大的应用潜力。

Abstract:

Passiflora edulis is highly susceptible to anthracnose during cultivation, and preventing the outbreak of this disease has become an urgent problem to be solved in its planting process. Six kinds of Chinese herbal extracts were prepared following standard methods. The inhibitory effects of these extracts on the mycelial growth of Colletotrichum gloeosporioides (the pathogen of passion fruit anthracnose) were detected by plate culture method at different concentrations (10, 20, 30, 40, 50 mg/mL). The results showed that at a concentration of 10 mg/mL, clove extract exhibited the strongest inhibitory effect on C. gloeosporioides, with an inhibition rate of 100%, followed by the extracts of Ligusticum chuanxiong, Angelica sinensis, Alpinia officinarum and Scutellaria baicalensis, while the inhibition rate of Stemona sessilifolia extract was only 30%. When the concentration reached 50 mg/mL, both clove and Angelica sinensis extracts achieved an inhibition rate of 100%; the inhibition rates of Ligusticum chuanxiong and Alpinia officinarum extracts exceeded 90%, and those of Scutellaria baicalensis and Stemona sessilifolia extracts were 84.43% and 78.10%, respectively. The six Chinese herbal extracts showed varying inhibitory effects on C. gloeosporioides, among which clove extract had the most significant performance, maintaining a 100% inhibition rate at concentrations of 10, 20, 30, 40 and 50 mg/mL, thus having great potential for the development of pesticides for the control of major diseases in P. edulis.
