Abstract

The present study aimed to investigate the impact of seed-borne mycoflora on soybean (Glycine max L.). Seed germination and subsequent seedling vigour are important factors for influencing crop establishment and yield potential. Six varieties of soybean seed samples viz. JS 95-60, JS 97-52, RSC 10-46, RSC 10-71, CG Soya-1 and seven seed-borne mycoflora viz. Fusarium spp., Alternaria spp., Colletotrichum spp., Cladosporium spp., Macrophomina spp., Penicillium spp. and Trichoderma spp. were selected for the experiment. A pot experiment was conducted to study the effect of seed-borne mycoflora on seed germination and seedling vigour of soybean. The results revealed that, among seed inoculation techniques maximum reduction in seedling vigour index over control was observed in Colletotrichum spp. (27.24%) inoculated seedlings and overall increased seedling vigour of soybean varieties was observed in Trichoderma spp. (26.52%) inoculated seedlings. Among soil inoculation techniques maximum reduction in seedling vigour index over control was observed in Macrophomina spp. (38.41%) inoculated seedlings and overall increased seedling vigour of soybean varieties was observed in Trichoderma spp. (24.40%) inoculated seedlings.

种子霉菌对大豆（Glycine max L.）种子发芽和幼苗活力的影响

本研究旨在探讨种传菌群对大豆(Glycine max L.)的影响。种子发芽和随后的幼苗活力是影响作物成材和产量潜力的重要因素。选用js95 -60、js97 -52、RSC 10-46、RSC 10-71、CG soy -1等6个品种的大豆种子样品和7种菌种，分别为镰刀菌、互交菌、炭疽菌、枝孢菌、Macrophomina菌、青霉菌和木霉。通过盆栽试验，研究了种传菌对大豆种子萌发和幼苗活力的影响。结果表明，在不同的种子接种方式中，炭疽菌(27.24%)接种的幼苗活力指数较对照下降最大，木霉(26.52%)接种的幼苗活力指数总体上有所提高。在土壤接种技术中，大褐霉(38.41%)接种的幼苗活力指数较对照降低最大，木霉(24.40%)接种的大豆品种幼苗活力总体提高。
