Survey and Collection of Arbuscular Mycorrhizal Fungi from 7 Provinces of Chilli Fields

Abstract

Surveys were made to collect of arbuscular mycorrhizal fungi (AMF) in chilli fields for 35 soil samples in 7 provinces. Mycorrhizal spores were sieved from soil samples by wet sieving and decanting method. The maximum number of spore was genus Glomus sp. Acaulospora sp. And Gigaspora sp. Respectively. Lsolate DAKA 5204 from Kalasin province was found the highest number of spores at 1,775 spores per 100 g of day soil while isolate DARB 5203 from Ratchburi province was found 6 spore per 100 g of day soil. All of them were able to produce and colonize root plants in pot culture using ruzi grass (Brachiaria ruziziensis) as the host plant at the glass-house of the Department of Agriculture. The isolate DAKB 5204 produced the highest number of spore in soil at 1,827 spores per 100 and 23.33% root colonization. The percent root colonization by DAKB 5202 was found the highest at 53.33% while the produccion of spores/g was 266 spores/g in soil
