采用气相色谱法和改进的高效液相色谱法研究发现：‘无核白’葡萄果粒为非跃变型呼吸类型，其乙烯释放量很低，但释放潜力很高，切伤后乙烯释放速率迅速增高；果梗和穗梗为跃变型呼吸类型，有很高的呼吸高峰和乙烯释放高峰。适量的ＳＯ２保鲜处理对葡萄的呼吸强度、脱落酸（ＡＢＡ）含量及乙烯释放具有明显抑制作用，对生长素（ＩＡＡ）、赤霉素（ＧＡ）有促进作用，既可抑制葡萄生理衰老，又可减轻葡萄的落粒，延长葡萄采后贮藏寿命
Gas chromatography and HPLC were used to study the results. The results showed that the non-nucleus white grapes were non-jumping respiration type with low ethylene release but high release potential. The release rate of ethylene after cutting injury was rapid Increased; fruiting stems and ear stems as the transitional respiratory type, high respiratory peak and ethylene release peak. Appropriate amounts of SO2 preservation had significant inhibitory effect on the respiration rate, ABA content and ethylene release of grapes, promoted the growth of IAA and GA, inhibited the physiological aging of grapes, It can reduce the grapes of grapes and prolong the storage life of grapes
