Popis: |
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 (Fv/Fm), and increased plant height (nongrafted only). Grafted plants maintained higher Fv/Fm 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. |
