Abstract:

Strawberry is one of the most widely cultivated plants all over the world and its fruits are very delicious and
rich in nutrients. However the fruits have a short life cycle, and are extremely susceptible to postharvest decay and not
shelf stable. Therefore, the studies on the factors regulating the ripening and senescence of strawberry fruits are of great
significance. The major objective of this paper is to review the current information about plant hormones such as ethylene
and abscisic acid (ABA), related enzymes such as lipoxygenase (LOX), superoxide dismutase (SOD) and catalase (CAT),
exogenous substances such as Ca2+, calmodulin, NO and hot water and related genes such as PLDa gene and the FAD gene
family, and the potential mechanisms involved in strawberry ripening and senescence. Endogenous substances and enzymes
not only exert their own functions at different levels by directly or indirectly influencing the functions of ethylene and NO,
but also interact with each other to regulate and control the process of ripening and senescence. Studies at the gene level are
still at the initial stage, although it has been revealed that they function by regulating the genes encoding enzymes related
to the synthesis and decomposition of the cell wall and cell membrane. This paper will hopefully provide comprehensive
information to study postharvest physiology and storage of strawberries.
