Inhibition of ethylene-induced -farnesene synthase gene PcAFS1 expression in ‘d’Anjou’ pears with 1-MCP reduces synthesis and oxidation of -farnesene and delays development of superficial scald
Pre-storage treatment of superficial scald-susceptible apple and pear fruits with the blocker of ethylene action 1-methylcyclopropene (1CP) inhibits the synthesis of -farnesene. Consequently, accumulation of -farnesene and its conjugated trienol (CTol) oxidation products n the fruit skin is diminished, and scald is largely prevented. In cold-stored apple fruit, a marked increase in expression o...
متن کاملInitial low oxygen stress controls superficial scald of apples
The effectiveness of initial low oxygen stress (ILOS) to control apple scald without postharvest application of scald inhibitors and fungicides was investigated. Scald susceptible (‘Granny Smith’, ‘Law Rome’, ‘Red Delicious’) and not susceptible (‘Idared’) fruits were harvested preclimacterically and treated at 1°C with (1) ILOS pretreatment or (2) no pretreatment as control. Fruit were then st...
متن کاملThe Effects of Fruit Maturity and 1-Methylcyclopropene (1-MCP) Treatment on α-farnesene Metabolism in Scald Resistant and Susceptible Cultivars of Apple Fruit
Background: It was found that, climatic conditions and fruit ripeness are important factor for the occurrence and intensity of superficial scald. 1-MCP is an inhibitor of ethylene action in plants and inhibits many ripening related processes along with the production of ethylene and volatiles. Objective: Apples are often held for several months at low temperature either in air (RA) or in con...
متن کاملHypobaric storage removes scald-related volatiles during the low temperature induction of superficial scald of apples
‘Law Rome’ and ‘Granny Smith’ apples were stored hypobarically in air at 5 kPa total pressure and also in air or controlled atmosphere (CA) at 1.5 or 3% O2 with 0 or 3% CO2, for 8 months at 1°C. Fruit were placed under hypobaric storage immediately after harvest or after 0.5, 1, 2, 3, 4, 5 or 6 months storage in air at 1°C to determine the effects of delaying imposition of hypobaric storage on ...
