Effects of arbuscular mycorrhizal fungi (amf) on Camellia sinensis (L.) o. kuntze under greenhouse conditions

The effects of arbuscular mycorrhizal fungi (AMF) on growth of tea both singly and in consortia were carried out in greenhouse environment for a period of 1 year. The effectiveness of native AMF species, viz., Acaulospora scrobiculata (A.s.), Glomus macrocarpum (G.m.), Rhizophagus intraradices (R.i.), on growth performance of C. sinensis plants were compared. The inoculating AMF noticeably increased the plant growth parameters such as number of leaves, leaf area, plant height, shoot length, root length, root and shoot weight (fresh and dry) and root: shoot (fresh and dry weight) ratio. The effect of individual and combined inocula of two as well as all the three different species of AMF on the growth parameters varied. In most of cases, consortium of all the three AMF species (A.s. + G.m. + R.i.) performed consistently better than the other inocula containing single as well as two AMF species. AMF colonization ranged from 30.69% to 81.26%. The study revealed the potential of AMF inoculation on growth of C. sinensis, regardless of single or mixed AMF consortium; thereby providing a promising resource for sustainable tea cultivation.
