Soft Wood Grafting in Mandarin (C. reticulata Blanco)

ABSTRACT Studies were carried out at ICAR Research complex for NEH Region Umiam, Meghalaya, India on soft wood grafting using Khasi mandarin under poly-house, net-house and open field conditions at 15-day intervals from 15 June to 15 October. Early sprouting, graft success and scion growth were found to be best under poly-house conditions. Similarly, maximum graft success rate and early sprouting were observed under the open field condition compared to the net-house but growth performance of the plants was better under the net-house. Grafting from 30 June to 15 August gave the maximum graft success, plant height, scion diameter, leaves, branches/plant and minimum days for sprouting under all three conditions. A gradual decrease in graft success and increased in days to sprouting were noticed after 15 August. Soft wood grafting of Khasi mandarin was also performed on different rootstocks (C. jambhiri, C. karna, C. reshni, C. latipes, C. taiwanica, Tanzelo dancy, C. grandis, Naity jamir and Karun jamir). Maximum graft success, plant survival, plant height, branches/plant and the minimum time to sprouting the graft were recorded in C. Jambhiri, while, leaves/plant, rootstock and scion diameter were best using Karun jamir rootstock.

Soft wood grafting in mandarin (C. reticulata Blanco): a novel vegetative propagation technique.

Studies were carried out at ICAR Research complex for NEH Region Umiam, Meghalaya, India on soft wood grafting in ‘Khasi’ mandarin under poly house, net house, and open field conditions at 15-day intervals from June 15 to October 15. Early sprouting, graft success, and scion growth were found to be better under poly house than other conditions. Similarly, the best graft success and early sprouting were observed to be better under the open condition than the net house, but growth performance of the plants was found to be better under the net house than the open condition. Grafting from June 30 to August 15 gave the best graft success, plant height, scion diameter, leaves, branch/plant, and minimum days for sprouting under all conditions. A gradual decrease in graft success and an increase in days to sprouting was noticed with grafting after August 15. Soft wood grafting of ‘Khasi’ mandarin was also performed on different rootstocks viz. C. jambhiri, C. karna, C. reshni, C. latipes, C. taiwanica, ‘Dancy’ tangerine, C. grandis, ‘Naity jamir’, and ‘Karun jamir’ rootstocks. The best graft success, plant survival, plant height, branch/plant, and minimum time for sprouting of the graft was recorded in C. jambhiri, while, leaves/plant, rootstock, and scion diameter was the best in ‘Karun jamir’ rootstock.
