| Abstract: |
| The impacts of salt and emamectin benzoate-chlorpyrifos mixture on physiochemical characteristics of non-heading Chinese cabbage were investigated using orthogonal experimental design and pot culture. Parameters such as chlorophyll, reducing sugar, soluble protein and cellulose of non-heading Chinese cabbage were chosen. Results showed that the physiochemical parameters were inhibited in varying degrees by salt and emamectin benzoate-chlorpyrifos mixture in a dose-effect mode. The values for these parameters decreased with increasing levels of contaminants. The main effect by using Duncan's new multiple range method analysis indicated that the pesticide had a significant effect while the salt had an extremely significant effect on physiochemical characteristics of non-heading Chinese cabbage. |
