Effects of Salt Stress on the Enzyme Activity and Chlorophyll Content of Bush Cinquefoil (Potentilla fruticosa L.)

Bush Cinquefoil (Potentilla fruticosa L.) also known as Prunus humilis, is a deciduous shrub of Potentilla of Rosaceae. Dense branches and leaves, yellow flowers, shaped like plum blossoms, flowering from June to July, suitable for garden ornamental shrubs or hedgerows Leaves and fruits contain tannin, which can be used to extract tannin extract. Tender leaves can be drunk on behalf of tea leaves. Flowers and leaves are used as medicines and have the effects of invigorating spleen, eliminating dampness, clearing summer heat, and regulating menstruation Bush Cinquefoil (Potentilla fruticosa L.), resistant to low temperatures of -50 and likes moist soil with good drainage. it is resistant to drought and barren. Bush Cinquefoil is an excellent greenery and medicinal plant, which has broad application prospect. However, the research and promotion of Bush Cinquefoil is still in its primary stage, mainly focusing on medicinal and reproductive aspects, while the research on salt resistance of Bush Cinquefoil is relatively few, and mainly under NaCl stress. Chloride and sulfate are the main salt damage components in the saline-alkali land in the arid region of northern China, which severely restricts the economic development in the arid region of northern China In order to expand the application of Bush Cinquefoil in saline-alkali regions in north China, especially in arid regions in north China, this project studied the effects of different concentrations of NaCl and Na 2 SO 4 solution treatment on antioxidant enzyme system and chlorophyll content of Bush Cinquefoil (Potentilla fruticosa L.) seedlings, in order to provide reference for improving the salt tolerance of Bush Cinquefoil and its application scope in north China.
