Abstract To explore the physiological mechanism of rice seeds’ tolerance to cold damage stress, the hybrid rice variety H-You 518 and the conventional rice variety Zhongjiazao 17 were used as experimental materials. A low-temperature cold damage treatment (4°C) and a normal germination treatment (25°C) were used to measure seed vitality, antioxidant enzyme activity, soluble sugar content, soluble protein content, α-amylase activity, endopeptidase, and related gene expression levels. The results showed that low temperature inhibited seed vitality and germination ability, and after restoring normal growth conditions, the activities of POD and CAT, as well as the content… More >
