Advance on Biological Effects of Ultra High pressure Treatment in Crop

Ultra High pressure (UHP) treatment is a new mutation technique and has been widely used in crop breeding.Compared with other technologies used for mutantion induction, UHP has many advantages including inheritability of induced variation, stability of mutations in offspring, simple equipment, lower cost and non pollution to human and environment.UHP is one of the effective ways to generate new gene sources and creating new germplasm.In this paper, UHP technique and its current status were briefly reviewed in view of its effects on growth and development, agronomic characters, physiology, biochemistry and molecular genetics.The problems of ultra high pressure were analyzed and discussed, its future application prospect in crop improvement was prospected.
