Abstract
A screening method for a drought-resistant germplasm of Ophiopogon japonicus related to the field of Ophiopogon japonicus planting is provided. The method uses Ophiopogon japonicus of the main production areas, which requires a large amount of water and rainfall during the growth period, the drought-resistant germplasm that is suitable for growing well is conducted with drought stress under the drought condition. The growth indicators and the physiological indicators of different Ophiopogon japonicus germplasm under drought stress conditions are comprehensively evaluated and ranked to evaluate the drought-resistant ability of the different germplasm. The screening method is scientific and effective, and can comprehensively evaluate the drought resistance ability of Ophiopogon japonicus under the drought stress conditions, laying a technical foundation for the screening and promotion of in the Ophiopogon japonicus with drought resistance ability.
