Abstract

Ethylene sensitivity of grafted and nongrafted tomato (Solanum lycopersicum) seedlings with three to four true leaves was examined. The concentration of exogenous ethylene that produced symptoms was between 1 and 10 μL⸳L^–1 regardless of grafting. Symptoms of ethylene exposure included leaf epinasty, decreased maximal photochemical quantum yield of photosystem II (F_v/F_m), and increased plant height (nongrafted only). Grafted plants maintained higher F_v/F_m than nongrafted plants in response to higher ethylene concentrations. Ethylene-damaged plants showed comparable growth to the control plants 3 weeks after transplanting, but transplant quality was diminished as a result of ethylene exposure at high concentrations.
