分别评价了棘孢木霉分离物01-52和CB-Pin-01的微球和新鲜培养物（真菌定殖的水稻种子）生物产品在减少脏穗或种子变色以及增加水稻变种（变种）的生长和产量方面的功效。柴娜1.将水稻种子浸泡（Sk）在真菌颗粒的孢子悬浮液（20 g/20 L）或真菌生物产品的新鲜培养物（100 g/20 L）中24小时。将浸泡的种子在播种前再孵育24小时。将21天龄的幼苗移栽到1 m2 × 3 m2的小块地块中。在生长期间用来自两种生物产品的孢子悬浮液喷洒（Sp）水稻植物三次。结果表明，与未处理对照相比，微丸01-52（Sk + Sp）和鲜培CB-Pin-01（Sk + Sp）制剂均显著增加了水稻的株高、每穴分蘖数、千粒重和总产量。与未处理对照相比，污整穗、污穗病粒和空粒的发生率显著降低，而健康种子的发生率增加。水稻根系定殖T.从幼苗到收获期检测到曲霉分离物01-52和CB-Pin-01。由贮存5个月的健康和脏穗感染种子生长的幼苗的幼苗活力指数和幼苗健康指数均显著高于未处理的对照。所有木霉处理增加了整粒加整精米，减少了糙米中的碎米。版权所有（C）2016，Kasetsart University.制作和主办：Elsevier B.

Wettable pellets and fresh culture (fungus-colonized rice seeds) bioproducts of Trichoderma asperellum isolates 01-52 and CB-Pin-01, respectively, were evaluated for their efficacy in reducing dirty panicle or seed discoloration, and to increase the growth and yield of rice var. Chai Nat 1. Rice seeds were soaked (Sk) in a spore suspension of wettable pellets (20 g/20 L) or a fresh culture of bioproducts (100 g/20 L) of the fungus for 24 h. Soaked seeds were incubated for another 24 h before sowing. The 21-day-old seedlings were transplanted into small plots (1 m(2) X 3 m(2)). Rice plants were sprayed (Sp) three times during the growing period with a spore suspension from the two bioproducts. The results indicated that both wettable pellet 01-52 (Sk + Sp) and fresh culture CB-Pin-01 (Sk + Sp) formulations significantly increased the plant height, number of tillers per hill, 1000-seed weight and total yield of rice compared to the untreated control. The incidence of dirty whole rice panicles, dirty panicle infected seed and empty seed were significantly reduced, while healthy seed were increased compared to the untreated control. Rice root colonization by T. asperellum isolates 01-52 and CB-Pin-01 were detected from the seedling through to the harvesting stage. The seedling vigor index and seedling health index of seedlings grown from 5 month-stored healthy and dirty panicle infected seeds treated by both wettable pellet 01-52 (Sk + Sp) and fresh culture CB- Pin-01 (Sk + Sp) bioproducts were significantly higher than the untreated control. All Trichoderma treatments increased whole kernels plus head rice and reduced broken rice in milled brown rice. Copyright (C) 2016, Kasetsart University. Production and hosting by Elsevier B.V.
