| Abstract:
Tomato plants (Lycopersicon esculentum Mill.) cv. Alicante, waterlogged in compost show greater increases in ethylene concentration than do those waterlogged in gravel. Changes in ethylene concentrations in plants grown in gravel correlate with increased WSD (water saturation deficit, but this was not the case for plants grown in compost, where changes in the plant correlate with increased ethylene concentrations in the soil. Studies using C14-ethylene show that while ethylene is taken up by tomato plants, passes to the aboveground parts and out through the leaves and stems, the amounts transported and emanated are very small. | |
