Abstract:
Mycorrhizal species of EndoGone are a
norll1Ll component of the soil mic:voflora in Hevea
cuI tivc tions. Soils speci8.11y in the {Jry zone
exhibi t a surprisine; vP,riety r'-11c1 richness in th,~
fungal flora studieo. AbunQcmce of extro.mLtric:::tl
spores inclicr te their gre,-],terimportance as a
source of infection, than spores pr00uced in
sporocarps.
Three gener~l of Enc1ogonaceae 8.no 2,180
over twenty species so f~r not reported from Sri
Lanka, are for the first time reported.
Pueraria seedline;s were inocul' tea with
root segments infectecl by cifferent species. An
exotic inoculurfiprove0 to be of best performance.
The local crude inoculwn, though quick to estc'blish
infection, is significantly less effective in the
long run.
Infection synthefJis was trieD out \iith
two conwonly avail8.ble spore types. Their only
difference w[-"sin colour. Spores took a considero,bly
longer time to infect than rootsegr'"lents.Successful
infection occured ':dtb only some of the yellow spores.
