Grafted tomato propagation: effects of light intensity and temperature on graft healing and plant regrowth

摘要

Grafting can improve vegetable productivity by combining desirable traits from two taxa into one plant. However, the grafting process creates severe wounds. Optimal healing of newly grafted plants requires careful light and temperature management (Leeet al., 2010). Grafted tomato plants are commonly healed in enclosed structures shaded to reduce light levels and moderate temperature (Rivard and Louws, 2006). However, what is the optimal combination of light and temperature conditions for efficient healing of grafted tomato plants is not clear. The hypothesis was that light and temperature affect the healing of grafted tomato seedlings separately and interactively.
