Effect of Plant Growth Hormones on Sprouting and Rooting Behaviour of Clones of Various Bamboo Species in coastal Odisha

Abstract

The present crisis has emphasized human dependency on bamboo with quality planting materials. A study focused on the effect of the different concentrations of IBA (0 ppm, 100 ppm, 200 ppm, 300 ppm) on the sprouting and rooting behaviours of 5 bamboo species viz. Dendrocalamus strictus, Bambusa vulgaris, B. nutans, B. tulda and B. bambos found in coastal Odisha in order to get an idea for mass multiplication and biomass production to meet the multifarious demands of bamboo based sector. It was carried out in Split-Plot Design with 3 replications with 5 species of bamboo as main plot factor band different concentrations of IBA as sub-plot factor. Different doses of IBA (0 ppm, 100 ppm, 200 ppm and 300 ppm) were prepared and those concentrations were poured inside the hole that were made with the help of a driller and then planted in prepared raised bed of 40x37 ft. After 3 months different parameters such as root length, leaf area, No. of roots, Above and underground Biomasses etc. are studied and observations were recorded. Max. no. of roots was observed in B. nutans for 0 ppm. Longest root length was recorded in B. nutans for 300 ppm. Max. fresh and dry below ground biomass was observed in B. nutans for 300 ppm and Max. Fresh and dry above ground biomass was recorded in B. nutans for 0 ppm and 300 ppm respectively. Mas. Quality index was recorded in B. nutans for 0 ppm and highest volume index was observed in B. vulgaris for 200 ppm.
