Development of Arbuscular Mycorrhizae and Leaf Blight Disease in Young Plantation of 25 Species of Bamboos

Abstract

Arbuscular mycorrhizal root colonization, spores of AM fungi in rhizosphere soil, incidence and intensity of leaf spot disease caused by Drechslera rostrata in 3-7 years old plantations of 25 different bamboos at Amravati, Maharashtra State was evaluated. Root colonization, spore number and disease incidence and intensity varied in different bamboos. There is no definite correlation in these parameters. Maximum root colonization was recorded in Bambusa vulgaris, B. nutans and Dendrocalamus asper. Maximum disease incidence was recorded in Dendrocalamus hamiltonii, D. asper, Bambusa ventricosa and Meloncanna baccifera. Among AM species Acaulospora scrobiculata showed the maximum frequency followed by Glomus intraradices, A. laevis and G. etunicatum
