| Abstract: |
| Liger 87-5 was used as test material to study leaf-removal and irrigation on the growth of tomato fruit under water controlling.The results showed that water controlling brought different effect on tomato fruit growth parameters.The parameters of fresh fruit growth in different treatments, such as fresh fruit growth rate, period of maximum fresh fruit growth, maximum fresh fruit rate, active growth period, slow-increase period, fast-increase period, slight-increase period and the growth period, showed as Control>Mild drought>Drough, Control>Leaf Removal, Control (30 mm) >Treatment (10 mm) .There was a positive correlation between the parameters and fresh fruit weight.Fresh fruit weight had significantly positive correlation with active growth period and the growth period, suggesting that the two parameters were the main factors affecting fresh fruit weight.All results indicated that drought stress and leaf-removal inhibited tomato fruit growth and decreased fruit weight. |
