A study to evaluate the effect of using different concentrations of rooting hormone on root and shoot characters of apical cuttings of V1 mulberry (Morus indica L.) raised using mini clonal technology at nursery level

Abstract

Research was done to standardize the rooting media and rooting hormone concentration in variety V1 apical shoot cuttings. Cuttings sown in sand: coir pith: FYM @1:1:1 ratio rooted 5cm deep and 15cm in length, giving the cuttings a higher chance of survival. Between treated and untreated cuttings, there were notable differences in shoot, root characters and the quantity of main roots. Cuttings treated with 3000 ppm IBA showed enhanced root number (no’s), shoot length (cm), no of leaves (no’s) and root length (cm). In apical shoot cuttings with active node, the number of roots and success rate of rooting were found to be maximum. The best outcomes for the mini-cuttings' root and shoot growth came from combining appropriate rooting medium with cuttings of the right kind and concentration of IBA, as per the improved methodologies. The findings suggested that V1 apical cuttings with healthy terminal bud might be utilized effectively in mini clonal technology to create saplings with potential vigour.
