Abstract:

Arbuscular Mycorrhizae (AM) is a type of endomycorrhizae in which fungus penetrates the cortical cells of roots of higher plants and forms vesicles and arbuscules. Plectranthus amboinicus (Lour.) Spreng is a perennial belonging to family Lamiaceae.In the current study open pot experiments were conducted to understand the influence of   Arbuscular mycorrhizae Glomus mosseae and Phosphate solubilizers Trichoderma viride, Aspergillus awamori and Trichoderma harzianum for 60,120 and 180 Days. Physical growth parameters like shoot and root length, stem and root girth, fresh and dry weight, root volume and leaf area were studied. Percentage root colonization studies were done and biochemical parameters pertaining to chlorophyll and carotenoid analysis were done. Glomus mosseae with Trichoderma viride proved to be the best treatment for Plectranthus amboinicus plant with maximum increase in shoot length, fresh weight, dry weight, number of leaves and number of branches. Percentage root colonization results revealed a consistent increase in Glomus mosseae with Trichoderma viride for 60, 120 and 180 days. Maximum increase in chlorophyll and carotenoid pigments was found in Glomus mosseae and Aspergillus awamori interaction. However future studies can be performed for standardizing different combinations of phosphate solubilizing fungi and arbuscular mycorrhizae species.
