摘　　要：以接种扩展青霉的"红富士"苹果为试材,通过测定不同温湿度贮藏期间果实中展青霉素含量、扩展青霉生长及相关生理指标的变化,从而明确贮藏温湿度对苹果产生毒素水平及相关生理调控的影响。结果表明:不同贮藏条件对接种后果实的腐烂程度及毒素积累量的影响为在2、15、25℃温度下,随温度的升高果实的腐烂程度加重,毒素的积累量增加。在65%~70%、75%~80%、90%~95%湿度下,随湿度的升高果实的腐烂程度加重,毒素的积累量增加。此外,低温低湿能有效降低接种苹果的呼吸强度及可溶性固形物含量,减少了展青霉素合成所需要的能量和底物,从而抑制展青霉素的合成。展青霉素的积累与苹果在贮藏期间的腐烂直径及乙烯释放量呈显著正相关,在25℃温度,90%~95%湿度下,接种苹果腐烂最严重,展青霉素积累量最大。说明贮藏条件与接种苹果腐烂直径及乙烯释放量与展青霉素的积累有密切关系。Taking ‘Fuji＇apples inoculated with Penicillium expansum as materials,the effects of different temperature and humidity during storage on the level of toxin produced and related physiological control was studied by measuring the changes of patulin content,the growth of Penicilliumspp.,and the related physiological indexes in different temperature and humidity storage conditions.The results showed that under the temperature of 2,15 and 25°C,the rotten degree and the accumulation of toxin increased with the rise of temperature;in the humidity of 65%-70%,75%-80% and 90%-95%,the decay degree and the accumulation of toxin increased with the augment of humidity.In addition,low temperature and humidity could effectively reduce the respiratory intensity of inoculated apples,the content of soluble solids and the energy and substrate needed for patulin synthesis,which thus inhibited the synthesis of patulin.There was a significant positive correlation between the accumulation of patulin and the diameter of decay and ethylene release during storage.The rot of apple could be most severe and patulin was the most abundant at a temperature of 25℃ and a humidity of 90%-95%.It showed that the storage conditions and diameter of the rot part of inoculated apple and ethylene release were closely related to the accumulation of patulin.
