Review of Research Progress in Crops' Response to Water Stress |
| |
| Abstract: | Drought is a main environmental factor that restricts the growth of crops.To understand the crops'reaction to drought stress is the prerequisite to drought resistance breeding.Drought tolerance mechanism of crops,the reaction of physiology biochemistry and the changes of ultrastructure under water stress were reviewed in this article.Some problems needed to be studied were given. |
