Effect of Low Temperature on the Development of Senescent Sports in 'Kluai Khai' Banana

Senescent spotting of banana (Musa AA group) cv Kluai khai developed durig the latter phase of ripening. Total phenolics, total sugars, ethylene production, respiration, phenylalanine ammonia lyase (PAL) and polyphenol oxidase (PPO) activities increased, while firmness of peel and plup decreased during ripening. Continuous exposure of bananas at color index 4-5 to 12, 15 and 18 oC reduced significantly sensecent spotting, total phenolics, total sugars ethylene production and respiration, while low temperature treatments increased activities of PAL and PPO of bananas. Exposure of bananas to 12 oC after the development of senescent spots did not inhibit further senescent spotting.
