| Abstract: |
| To supply scientific basis for the proper planting mode of hot pepper, an experiment was conducted in 2007-10～2009-09 to study the growth, enzyme activity of l
eaves, fruit quality and the correlation between enzyme activity and quality of hot pepper with different proceding crops. The test determined the morphology, enzyme activity, yield and quality of peper fruit with the method of the combination of the field investigation and indoor experiment. The results showed that: (1) Both the asparagus lettuce stubble and garlic stubble not only increased sharply the area and enzyme activity of leaves, but also decreased the malondialdehyde (MDA) content. The wheat stubble increased significantly the content of vitamin C (Vc). (2) The yield of hot pepper in the wheat stubble treatment was lower than the asparagus lettuce stubble and garlic stubble treatments. (3) There was remarkably positive correlation between MDA of leaves and Vc content of fruit, but significantly negative correlation between MDA and water content of fruit. There was remarkably negative correlation between catalase (CAT) activity of leaves and Vc content of fruit. Both the garlic and asparagus lettuce were proper proceding crops for hot pepper in this experiment. |
