In this study, effects of the low light irradiation under low temperature on the quality of vegetables-and-fruits were investigated from the viewpoint of morphology, physiology and ecological.1. In the vegetables-and-fruits which irradiated the low light, the weight decreased, and the vegetable quality lowered. The rate of weight loss was higher, as the storage temperature and the light intensity were increased. The weight loss were related to the increase of transpiration by the rising of the surface temperature of vegetables by light irradiation2. When the vegetables-and-fruits was packed in MA bag and then storage condition was the optimum for temperature and light condition, the degeneration of the green was suppressed, and the. decrease of eating quality and appearance in the, vegetable was small. In the vegetables-and-fruits which irradiated light, the chlorophyll content increased, the physiological activity of a chloroplast was maintained highly, the function of a nourishment t … More ransportation path was maintained, generation of the ethylene which is aging hormone was controlled, and generation of volatile component by the anaerobic respiration were suppressed, were showed. Therefore Maintenance of the quality by the irradiation was considered that control of the physiological activity of the cell and the generation of the chlorophyll by optical irradiation and photosynthesis is related.3. When Brassica chinensis var. komatsuna in MA packaging was stored with water -supply under the low light irradiation, the leaf color became deep, and the nitrate nitrogen concentration of the plant was reduced by about 36%, and this tendency was remarkable in the storage temperature at 14℃.4. when the vegetables-and-fruits with chlorophyll was stored by combining low light irradiation (50-2501x), low-temperature (5-10℃), high humidity condition ( the MA packaging, etc. ), the leaf color was maintained by the photosynthesis, and the lowering of the quality was able to suppressed.

本研究从形态学、生理学和生态学的角度研究了低温弱光处理对果蔬品质的影响.弱光照射的蔬菜和水果，重量减少，蔬菜品质下降。随着贮藏温度的升高和光照强度的增加，其失重率增大。光照射使蔬菜表面温度升高，增加了蒸腾作用，从而增加了蔬菜的失重率。果蔬采用MA袋包装，在适宜的温度和光照条件下贮藏，可抑制绿色的退化，提高果蔬的品质。蔬菜的食用品质和外观下降幅度较小。经光照处理的蔬菜和水果，叶绿素含量增加，叶绿体的生理活性得到高度维持，营养物质的功能得到加强。 ...更多信息 结果表明，保持了运输途径，控制了老化激素乙烯的产生，抑制了无氧呼吸产生挥发性成分。因此，认为通过光照射保持品质与光照射控制细胞生理活性和叶绿素的产生以及光合作用有关.小白菜（Brassica chinensis var. MA包装的小松菜在弱光条件下供水贮藏，叶色变深，植株体内硝态氮浓度降低约36%，在14℃贮藏温度下这种趋势显著.含叶绿素的蔬菜水果采用弱光（50- 2501倍）、低温（5-10℃）、高湿（MA包装等）相结合的贮藏方法，可通过光合作用维持叶色，抑制品质下降。少
