禾本科植物内生真菌研究16:内生真菌Neotyphodium sinicum对宿主鹅观草生长的影响
Grass endophyte researches 16:effects of endophyte Neotyphodium sinicum on botanical characters of its host Roegneria kamoji
摘要
Abstract
Mature seeds of Roegneria kamoji from an isolated population grown in Nanjing in 2008 were collected. Seedlings rose followed by germination tests. Their agronomic properties including tiller number,plant height,and width of the pseudostems and leaves were investigated in next spring. Endophyte infection of each plant was detected by staining techniques. Enhanced growth and tillering were recognized in endophyte-infected plants,but plant height,and width of the pseudostems and leaves were not significantly affected by the endophyte infection. Morphological and phylogenetic evidences indicated that the fungal isolates from those endophyte infected plants should be Neotyphodium sinicum Wang.Ji et Kang. This is the first report of N. sinicum affecting agronomic properties of its hosts in the field. Plant growth and tillering enhanced by endophyte infection were firstly observed on Roegneria kamoji plants.关键词
