Abstract


Nyamplung (Calophyllum inophyllum L) is known to be associated with AMF, but it is still unknown whether the association has begun to occur when cotyledons are still present or starting at a certain level of regeneration. Research has been done in Pecal Beach Kinjil River in Ketapang district. The purposes of the research are: (1) to assess the amount of spores and genus AMF associated with its development in the rhizosphere of nyamplung regeneration nature seedling stage from 10 cm to 150 cm, and (2) to determine root infection percentage in order to know the level of the association at any size of penage regeneration seedlings. The research is a field research by survey method with sampling technique against natural regeneration seedling level of 10 cm, 30 cm, 60 cm, 90 cm 120 cm, and 150 cm. The data was collectedin laboratoryon the form of the number of spores and genus AMF and the percentage of infections in the roots. The research results showed that there were 616 AMF spores fruit / 100 g of sandy soil consisting of the genus Glomus ( 597 pieces / 100 g sandy soil), Gigaspora ( 15 pieces / 100 g sandy soil) and Scutellospora ( 4 pieces / 100 g sandy soil). The development of the number of spores increased from the height of the seedling's natural regeneration measuring was 10 cm to 150 cm. The results of observations on the roots found thatAMF infection is in the form of vesicles and arbuscular. Infection at the root of natural penage regeneration from 84.44-100%, indicating the level of association between AMF and nyamplung seedling's natural regeneration in the high class ( grade 5 ) .
