Relationships between canopy temperature and biological characters of wheat under drought conditions

Abstract

Abstract: Based on the long-term observation of canopy temperature and biological characters of wheat,we discovered a kind of cold type wheat that can maintain a low canopy temperature.Under drought condition,its canopy temperature was continuously lower than that of control,especially during milk-filling stage.Many of its biological characters,such as chlorophyll content,net photosynthetic rate,soluble protein content and SOD activity etc,were superior to those of warm type wheat,which make it grow more efficiently under drought condition.The discovery is very important to the variety selection and is useful to improve wheat yield and quality in dry farmlands.
