INTRODUCTION Chalutz et al.' *. have shown that the ex tent of chilling injury after storage at temperatures Citrus are one of the rmost important sub- tanging from 2-12"C varicd in different citrus tropical fruit in the world. As shown in Table 1, cultivars. Hasegaw,' and lbal 7 have investigated annual production throughout the world in 1985 the cffect of ambient temperature on the peel color was 58,438,000 rut, which was much the same of .ome citrus cultivars grown in Japan. production level as banana (including plantain) or It is well known that the temperature affects grapes (including grapes for wine), the relative humidity in the ambient atmosphere. Several citrus varieties, including orange, Any change of temperature in the storage room is tangelo, mandarin, clemenn'ne, satsu:,., lemon, accompanied by a chanje in the relative humidity. lime, grapefruit and pomelo, are grown in Asicn For this reason, it is necessary when studying the countries (Tabie 2). Production in Asia is 22.24% effect of different storage temperatures to consider of the world's total citrus production . the simultaneous effect of humidity. The most important citrus grown in Asia are This paper will deal with the effect of the oranges, followed by tangelo, the mandarin group, temperature and humidity levels in storage facilities lemons and other sour citrus, and granefruit. on physiology and storage quality in several citrus Citrus fruits have a relatively long postharvest varieties. life in compari~cn with other subtropical and trop ical fruit. The type of handling before and after MATERIALS AND METHODS harvest, and the citrus variety and culivar, may both influence fruit quality in marketing.
