Abstract:

Soil secondary salinization has been a common phenomena in vegetable protected culture, mainly as a consequence of improper fertilizer application, unsuitable culture and management practices, less raining rinse and so on, leading to the progressive accumulation of salts in the soil, which inhibits vegetable growth and development, causes decline of yield and quality, brings a negative effect on sustainable development of vegetable. It showed that grafting could improve vegetable tolerance to environmental stresses, became an effective approach to overcome salt stress. In the article, it provided advances of plants by grafting under salt stress, including growth and development, ion distribution, photosynthesis, osmotic substances, antioxidative enzymes and endogenous hormones etc, and the problems and prospects on these relative studies about grafting were put forward. This review may help to study the salt-tolerant mechanism of plants by grafting.
