Dynamics of the diversity of fungal and Fusarium communities during continuous cropping of cucumber in the greenhouse.

摘要: The continuous cropping of cucumber in the same potting soils may result a reduction yield and quality crop, phenomenon described as soil sickness. changes microbial communities affected by link between these sickness are still not clear. In present study, was cropped pots under greenhouse conditions for nine successive cycles. Structures sizes rhizosphere fungal Fusarium (Ascomycota, Fungi) communities, both ubiquitous ecologically important soils, were analysed with PCR-denaturing gradient gel electrophoresis quantitative reverse transcription PCR, respectively. Cucumber showed retarded growth seventh cycle. RNA- DNA-based community structures derived from sample differed each other, active more sensitive to cropping. RNA-based larger cycle than other Overall, findings this study indicate that population rather diversity fungi linked associated cultivation.
