1-MCP controls SS and extends storage life of both green and
red ‘Anjou’ pears. The 1-MCP treated red but not green pears can
develop RC in response to PSEC following 6–7 months of cold
storage. Ethylene production increased in 1-MCP treated red but
not green pears in later stage of cold storage, and the ethylene
synthesis was enhanced in red but not green pears by PSEC
following 6–7 months of storage. The enhanced ethylene
biosynthesis and development of RC in red ‘Anjou’ pears by PSEC
was regulated by the expression of PcACO1. PSEC is a commercial
standard procedure for conditioning European pears. Therefore, 1-
MCP pre-storage treatment plus PSEC could be an alternative to
ethoxyquin for controlling SS and extending storage life of red‘Anjou’ pears. Further study is needed to understand the effect of
anthocyanin synthesis on ethylene biosynthesis in pear fruit and
its response to 1-MCP
