Abstract:

Abiotic stress is one of the main factors affecting the growth and yield of vegetable crops worldwide. Therefore,how to improve the stress resistance of vegetables has become a research hotspot. As the largest vegetable planted in China,hot pepper(Capsicum annuum L.)has high nutritional value and economic value. Therefore,it is of great social benefit to cultivate hot pepper varieties with strong resistances. Based on this,this study focuses on the responses of hot pepper to temperature stress,saline-alkali stress,water stress and heavy metals stress that caused changes in plant morphological status,physiological,biochemical and molecular level. The improvement measures were firstly integrated,and the pepper to future research direction was analyzed,which would provide references for the development and utilization of resources and resistant variety breeding.

Key words: hot pepper(Capsicum annuum L.), temperature stress, saline-alkali stress, water stress, heavy metal stress
