Progress in water stress physiology and drought tolerance mechanism of horticultural plant;

Drought tolerance mechanism of crops,the reaction of physiology biochemistry and the changes of ultrastructure under water stress were reviewed in this article.

This paper reviewed the development situation of aerobic cultivation in lowland rice on its main physiological characteristics,drought-resistant mechanism,high-yield cultivation technique and existing problems.

This paper elaborated vegetation transplant plan on the loess plateau highway side slope and the drought-resistant mechanism,and pointed out the main existent questions,for example,barren soil,low water ratio and plants are difficult to survive.

Studying and exploring the drought-resistance mechanism have become the point to which lots of researchers is paying attention.

This paper summarized the research advances in the drought resistance mechanisms of tree species from the aspects of water relationships among tree species,net photosynth.

This paper analyzed the response mechanism of the trees to water stress,such as growth traits,morphological structure and physiological biochemical index,and then discussed their drought resistance mechanism from all aspects.
