Abstract

Introduction: The biological activities of osthole have been widely reported in recent years. However, few studies have been conducted on osthole in agriculture, and its effects on plant growth have little been reported.

Methods: Three experimental treatments were set up in this experiment: blank control (CK), osthole (CLS), and B. amyloliquefaciens (LKWS). In this study, the effects of osthole and Bacillus amyloliquefaciens on the growth parameters, photosynthesis, antioxidant enzyme activities, disease incidence, and microbiome of forested P. quinquefolius were tested.

Results: This study demonstrates that the use of osthole and B. amyloliquefaciens significantly improved the growth of Panax quinquefolius in a forest compared to that in the control treatment, increased the total chlorophyll and carotenoid content of P. quinquefolius, significantly increased its net photosynthetic rate, and decreased the stomatal conductance and intercellular CO2 levels. In addition, the use of osthole and B. amyloliquefaciens significantly improved ascorbate peroxidase and peroxidase (POD) activities, enhanced antioxidant activities of the P. quinquefolius POD, and reduced the disease incidence and index of American ginseng anthracnose. Based on the American ginseng microbiome analysis, the use of osthole and B. amyloliquefaciens could change the structure of the American ginseng microbial community, significantly increase the diversity of American ginseng bacteria, significantly decrease the diversity of American ginseng fungi, stimulate the recruitment of more growth-promoting microorganisms to American ginseng, and build a more stable microbial network in American ginseng.

Discussion: In conclusion, we found that the application of osthole had a positive effect on the growth of American ginseng, providing a theoretical basis for its subsequent application in agriculture.

蛇床子素和解淀粉芽孢杆菌对林内西洋参生理生长的影响。
近年来,蛇床子素的生物活性被广泛报道。然而,关于蛇床子素在农业上的应用研究很少,其对植物生长的影响也鲜有报道。方法:本试验设置空白对照(CK)、蛇床子素(CLS)和解淀粉芽孢杆菌(LKWS) 3种处理。本试验研究了蛇蛇素和解淀粉芽孢杆菌对林分西洋参生长参数、光合作用、抗氧化酶活性、病害发生率和微生物组的影响。结果:本研究表明,与对照处理相比,在森林中施用蛇麻素和解淀粉芽孢杆菌显著促进了西洋参的生长,提高了西洋参的总叶绿素和类胡萝卜素含量,显著提高了西洋参的净光合速率,降低了西洋参的气孔导度和胞间CO2水平。此外,蛇床子素和解淀粉芽孢杆菌显著提高了抗坏血酸过氧化物酶和过氧化物酶(POD)活性,增强了西洋参过氧化物酶(POD)的抗氧化活性,降低了西洋参炭疽病的发病率和指数。通过对西洋参微生物组的分析,蛇床子和解淀粉芽孢杆菌的使用可以改变西洋参微生物群落的结构,显著增加西洋参细菌的多样性,显著降低西洋参真菌的多样性,刺激更多促进生长的微生物向西洋参招募,构建更稳定的西洋参微生物网络。综上所述,我们发现蛇床子的应用对西洋参的生长有积极的影响,为其后续在农业上的应用提供了理论依据。
