Influence of AM fungi and its associated bacteria on growth promotion and nutrient acquisition in grafted sapota seedling production
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 1
Abstract
A study was undertaken to know the effect of co-inoculation of Arbuscular Mycorrhizal (AM) fungi and its associated bacteria on enhancing AM root colonization, growth promotion and nutrient acquisition in grafted sapota plants. The best mycorrhiza associated bacteria i.e. Pseudomonas putida (HM590707) isolated from Funneliformis mosseae spore was evaluated along with AM fungi for growth promotion and AM fungal colonization in grafted sapota plants. The combined application of P. putida along with AM fungi significantly increased plant height (39.67 %), stem girth (3.2 cm), total biomass (66.8 g plant-1), AM root colonization (73.4 %)and plant nutrient concentrations viz., N (2.52 %), P (0.18 %), K (2.90 %), Fe (428.4 ppm) and Zn (21.40 ppm) as compared to uninoculated control. This finding clearly demonstrated that grafted sapota plants can be successfully established by combined inoculation of AM fungi and its associated bacteria which have a greater impact on healthy grafted plants.
