Influence of Season and Phytohormones on Rooting Behaviour of Green Bamboo by Cuttings

Abstract

Bamboos are important sources of income for rural households in India and elsewhere. Bamboo is increasingly identified as potential species for poverty reduction programs in many countries including India. The present study was carried out to develop the farmer’s friendly protocol for mass multiplication of Bambusa vulgaris through ex vitro methods. During the present study rooting was obtained in three seasons except winter season and the variation in all the physiological characters with seasons & treatments were significant at P<0.001. Maximum average (62.00) rooting percentage and (24.41 cm) root length was found in rainy season followed by summer season with average (50.33) rooting percentage and (15.31 cm) root length. However, (47.33) rooting percentage and (16.80 cm) root length was achieved in spring season. Among the three auxins used for pretreatment, IBA showed more positive response on rooting as compared to IAA and NAA. In winter season no rooting and sprout were observed in any treated cuttings.
