Effect of environment on grafting success in jackfruit.

摘要

The effects of the period of grafting (July, August, September, October, November and December 2004, and January 2005) and environment (mist, 50% agro-shade or tree shade) on the success of softwood grafting in jackfruit were studied. The mist chamber constructed with a polyethylene sheet as the roofing material contained equipment that supplied intermittent mist. Commercial 50% agro-shade net was raised at a height of 3 m from the ground. Tree shade (more than 50%) was provided by closely planted jackfruit trees. Approximately 360 seedlings were grafted per month. Grafting success was highest when seedlings were grafted in October. Among the environments, 50% agro-shade resulted in the lowest number of days to graft union (20.89), and highest percentage of graft-take (17.96%) and sprouting (23.3%) on the 60th day.
