Previously published data from tomato plants grow in nutrient solutions having one of three electrical conductivities (2,12 and 17 mS cm1) were analysed. The rate of water import into the fruit, and the proportion of this conducted by the xylem stream were calculated from the daily rates of transpiration and the net accumulation of water and calcium. The rate of water import decreased as the conductivity of the nutrient solution rose, the maximum daily import rates in the third week after pollination being 3.2, 3.0 and 1.8g fruit for fruit grown at 2, 12 and 17 mS cm, respectively. During fruit development, the proportion of water imported via the xylem fell from 8-15% to 1-2% at maturity. |
