| Abstract: | Under chilling stress, humic acid which was sprayed to the leave of rice (Ha 93-63) can improved it physioiogical resistance. Some physiologicai factors were raised, such as:the content of free proline, the activity of polyphenol oxidase (o diphenol oxygenoxidoreducease, EC1 10 3 1) and the content of abscisic acid in the plant tissue, while both of thepermeability of the plasma membrane and the content of malondialdehyde in the leave. The expermental results were showed: humic acid certainly ceused the reslstance on rice to chilling injury. |
