Peel tissue a-farnesene and conjugated trienol concentrations during storage of ‘White Angel’× ‘Rome Beauty’ hybrid apple selections susceptible and resistant to superficial scald
In a 2-year study, fruit from eight redand eight yellow-skinned ‘White Angel’× ‘Rome Beauty’ hybrid selections were stored for 21 weeks at 0.5°C plus 1 week at 20°C and evaluated for the incidence and severity of superficial scald. Five red-skinned (R-03, R-20, R-22, R-48 and R-85) and three yellow-skinned (Y-26, Y-55 and Y-65) selections were examined in both seasons. Peel-tissue samples taken...
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 کاملInhibition 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...

Superfi cial scald of apples and pears, which manifests as brown or black patches on the fruit skin, results from necrosis of the hypodermal cortical tissue (Bain and Mercer, 1963) and is thought to be induced by oxidation products of the sesquiterpene (E,E)-α-farnesene (Anet, 1972a; Huelin and Coggiola, 1970a, 1970b; Huelin and Murray, 1966). Synthesis of sesquiterpenes in plant tissues occurs...
