Effect of bio-regulator treatment, wounding and growing media on survival and vegetative growth of stem cutting in lemon (Citrus limon Burm.)

Abstract

The present investigation was carried out to know the effect of bio-regulator treatment, wounding and growing media on survival and vegetative growth of stem cutting in lemon (Citrus limon Burm). The results of the propagation study revealed that stem cuttings of lemon when treated with wounding + 4000 ppm IBA and grown in soil + sawdust + vermi-compost had recorded significantly earliest sprouting (6.92 days) and highest sprouting percent (79.38%), survival percent (76.38%), plant height (19.80 cm), number of shoots/cutting (7.34), number of leaves/cutting (12.88), stem girth (2.15 cm). The results also revealed that ‘wounding’ (without IBA treatment) was found to be least significant among chemical and mechanical treatments in respect of above parameters of stem cutting.
