Fruit Respiration and Ethylene Production.

Effect of Gamma Radiation on Rate of Ethylene and Carbon Dioxide Evolution by Lemon Fruit

“…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 0.17 ppm ethylene. Mlaxie et al (7) showed that 50 kilorads (Krad) or more of gaimma radiationl ilmarkedly stillmulated CO.. evolutioni by lemiioln frtits.…”

Physiological Studies of Chilling Injury in Citrus Fruits

“…Stimulation of the respiratory rate at chilling temperatures has been reported for cucumbers (8) and for swveet potatoes (12). The influence of a previous exposure to chilling temperatures on the respiratory rate and trends at nonchilling temperatures has been investigated (1,4,5,6,8,10,17,18). Most, but not all of these studies showed the initial rates of CO9 evolution, after transfer to the warmer temperature, rising to a maximum well above the value normally expecte(d and then slowly falling back to the expected value.…”

Interrelationships of Ethylene and Abscisic Acid in the Control of Rose Petal Senescence

“…This increase was argued as being only a by-product of fruit ripening processes (6). However, the concept of ethylene being a ripening hormone is now well established (8).…”
