Abstract

Shoot roots are second type of root, which emerge from the base of the new shoots, 5-7 days after planting. The shoot roots growth on single bud chips seedling is critical for further growth in dry land. The objectives of this study were to examine shoot root growth using different doses of arbuscular mycorrhizal fungi (AMF) inoculum on five clones of sugarcane and to ascertain their effect on seedling biomass weight. The highest and lowest temperatures on the research site were 32 and 18 C, in tropical monsoon climate. The experimental design was a completely randomized design (CRD) in 4x5 factorial arrangement with four replicates. The treatments were: four doses of AMF inoculum (0, 1, 2, 3 g/bud chips) on five clones with single bud chips seedling (PS864, KK, PS881, BL, and VMC). The evaluated parameters were root colonization affected by doses of AMF inoculum, number of shoot roots, surface area of shoot and total roots, root length, biomass seedling, and P leaf concentration affected by doses of AMF inoculum. AMF inoculum doses of 2 and 3 g of inoculum/bud chips resulted in the speed and extent root colonization at 5 days after inoculation on all five sugarcane clones. The clones exhibited 57-100 % accelerated emergence of shoot roots (i.e. the second roots formed), increased total root length, total root surface area especially on BL, VMC, and P leaf concentration. Application of 2-3 inoculum/bud of AMF inoculum significantly increased shoot roots growth i.e. root length, root surface area, and number of shoot roots.
