Abstract:

以桃棕哥斯达黎加San Carlos种源及14152号家系幼苗为宿主,开展接种丛枝菌根真菌(地表球囊霉、苏格兰球囊霉和木薯球囊霉)的试验研究。结果表明:参试的3个丛枝菌根真菌均可在桃棕San Carlos种源和14152号家系上形成感染,感染率26.7%~50.0%,感染指数13.3~37.5。尽管形成了菌根感染,但接种后7个月时,对桃棕San Car-los种源和14152号家系的地上部分的生长均未产生显著的影响;菌根接种对14152号家系根系的生长产生显著的促进作用(P<0.05)。木薯球囊霉G3008菌株接种处理下,14152号家系幼苗根系生物量和主根长分别比不接种(对照)提高了80.0%和51.4%。3个丛枝菌根菌中,木薯球囊霉G3008菌株对桃棕家系苗期根系发育有较好的效果。
