Dardizing cutting size of mulberry (Morus sinensis) for mini clonal technology

Abstract

An attempt was made to standardize a sound protocol for mini clonal propagation of mulberry (M. sinensis). Different sized apical shoot cuttings viz., 2 cm, 4 cm, 6 cm, 8 cm, 10 cm and 15 cm were harvested from mother plants of M. sinensis. Such cuttings were treated with different growth regulators viz., IBA and NAA @ 5000 ppm and raised in mistless polytunnel. The growth parameters viz., shoot length, rooting percentage, root length and root shoot ratio were taken. Among the sizes, cutting size of 15 cm treated with IBA @ 5000 ppm recorded highest survival percentage of (43.00%) followed by NAA (35.00%).
