Nutritional control of regreening and degreening in citrus peel segments.
A method for reversibly regreening and degreening citrus epicarp in vitro using peel segments was developed.Peel segments from mature degreened fruit promptly regreened when kept in light upon agar medium containing low (15 millimolar) concentrations of sucrose. Higher concentrations of sucrose inhibited this regreening, but NO(3) (-) and certain amino acids included in the media overcame the i...
متن کاملIncrease in Free and Bound Abscisic Acid during Natural and Ethylene-induced Senescence of Citrus Fruit Peel.
Free and bound abscisic acid and neutral growth inhibitors were detected in citrus fruit peel using two bioassays and gasliquid chromatography. None of the inhibitor components seems to be directly associated with chloroplasts or chromoplasts in citrus fruit peel.Green, nonsenescent fruits contain mostly neutral inhibitors and relatively low amounts of free and bound abscisic acid. Upon harvest...
متن کاملLow-temperature-modulated fruit ripening is independent of ethylene in ‘Sanuki Gold’ kiwifruit
Fruit ripening in response to treatments with propylene, 1-methycyclopropene (1-MCP), and low temperature was characterized in 'Sanuki Gold' kiwifruit, Actinidia chinensis Planch. Propylene treatment immediately induced rapid fruit softening, increased AC-PG (polygalacturonase) and AC-EXP (expansin) mRNA accumulation, and stimulated an increase in the soluble solid concentration (SSC) and a dec...
متن کاملEffect of Gamma Radiation on Rate of Ethylene and Carbon Dioxide Evolution by Lemon Fruit.
Freshly harvested lemon fruits show a declining respiratory rate and, therefore, have been classified as nonclimiiacteric fruits (1). Biale et al. (2), usinga a manomiietric technique, founid no evidence for ethylenie production by lemiioni fruits; but when Burg and Bturg (4) employe(d a highly selnsitive gas chromatograph, they founid the internal atmosphere of lemon fruits containie(d 0.11 to...
متن کاملDifferential feedback regulation of ethylene biosynthesis in pulp and peel tissues of banana fruit.
The feedback regulation of ethylene biosynthesis in banana [Musa sp. (AAA group, Cavendish subgroup) cv. Grand Nain] fruit was investigated in an attempt to clarify the opposite effect of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, before and after the onset of ripening. 1-MCP pre-treatment completely prevented the ripening-induced effect of propylene in pre-climacteric banana f...
