摘要

Sclerotium rolfsii is a soil-borne plant pathogen that causes root diseases in hundreds of plant species. It also causes collar rot disease in chickpea (Cicer arietinum L.). The present pot study was carried out to investigate the effect of soil amendment with dry biomass of a weed Chenopodium album L. and two antagonistic fungi, namely Trichoderma harzianum and T. viride, on growth and yield of chickpea variety Noor 2009 in soil infected with S. rolfsii. The pathogen-contaminated soil was amended either with 1, 2, or 3% C. album dry biomass, T. harzianum, and T. viride alone, or combinations of either of the two Trichoderma species and plant dry biomass. The lowest shoot and root dry biomass and grain yield of chickpea were recorded in S. rolfsii inoculation alone without any soil amendment (positive control). Plant growth and yield were significantly and gradually increased over positive control with an increase in C. album dry biomass application in the soil. Likewise, soil application of either of the two Trichoderma species significantly enhanced plant growth and yield over positive control under biotic stress of S. rolfsii. Combined application of either T. harzianum or T. viride with 3% dry biomass of C. album also proved highly effective in alleviating biotic stress of S. rolfsii on growth and yield of chickpea.

Rolfsii。将病原体污染的土壤用1,2或3％C.奖金干生物量，T. harzianum和T.Vitide单独进行，或两种Trichoderma种类和植物干生物量中的任何一种。单独的S.Rolfsii接种的鸡眼的最低枝条和根系干生物量和籽粒产量没有任何土壤修正（阳性对照）。植物生长和产量显着且逐渐增加了阳性对照，随着土壤中的C.相册干生物量应用增加。同样，两种richoderma物种中任一项的土壤应用显着增强了植物生长和S.Rolfsii生物胁迫下的阳性控制率。 Harzianum或T.Viride的组合施用C.专辑的3％干生物量也证明了缓解S. rolfsii的生物胁迫对鹰嘴豆生长和产量的高度有效。
