Abstract:

In order to increase the drought resistance capability of Solanum integrifolium Poir. the research used plant growth retardants: PP333, B9 and CCC to spray on leaves in dry conditions and took their leaves to measure their physical signs. The data showed results that plant growth retardants have raised proline content and SOD activity, reduced MDA content and soluble sugar content, including PP333 have improved chlorophyll content of Solanum integrifolium Poir. So the plant growth retardants have increased the Solanum integrifolium Poir.’s drought resistance at a certain degree except decreased the root biomass by spraying PP333 and CCC and CCC caused phytotoxicity. Within this chemicals concentrations range, the concentrations 400 mg/L of PP333, 6000 mg/L of B9 and 4000 mg/L of CCC were the best in them.
