Selection of rice plants resistant to high temperature ripening in rice seedlings

摘要

Problem to be solved: to provide a method for selecting a rice plant resistant to high temperature ripening damage within the period of 14 days after seedling stage, specifically after germination.A method for selecting a rice plant resistant to high temperature ripeningRice varieties or linesAfter germination treatmentBy regular solution culture for hydroponicsUnder 12 hours of 12 hours dark periodTwo different temperature conditions.High temperature ward, 35 degrees Celsius, 30 ℃In the control zone which is 25 degrees Celsius of 20 degrees CelsiusGrown for 14 daysOn the basis of the difference in the growth rate of the ground or underground of the high temperature and control zones during cultivation or during cultivationIt is selected as rice plant resistant to high temperature ripening damage or rice plant resistant to high temperature ripening damage in the seedling stage.Diagram
