Abstract
Vesicular-arbuscular mycorrhizal colonisation was assessed on one year old coconut seedlings of 17 cultivars and 4 hybrids, growing in a sandy loam soil. The proportion of root segments with vesicular-arbuscular mycorrhizae ranged from 56·8–95·2%. In general, more root segments of tall cultivars were infected (68·8–95·2%) than those of dwarf cultivars (62·4–75·2) and hybrids (56·8–86·4%). Similar trends were detected in the infection grading and when the spores in soil near to seedlings was examined. The extent of vesicular-arbuscular mycorrhizal colonisation within infected root segments of same cultivars also varied. The vesicular-arbuscular mycorrhizal fungi associated with coconut seedlings includedGigaspora decipens, Gigaspora aurigloba, Gigaspora rosea, Glomus multicaule andGlomus fasciculatum.
