摘要

Although fleshy fruit is mainly made up of water, little is known about the impact of its water status on sugar metabolism and its composition. In order to verify whether fruit water status is an important driver of carbohydrate composition in tomato fruit, an adaptation of the SUGAR model proposed previously by M. Genard and M. Souty was used. Two versions of the model, with or without integrating the influence of fruit water content on carbohydrate metabolism, were proposed and then assessed with the data sets from two genotypes, Levovil and Cervil, grown under different conditions. The results showed that, for both genotypes, soluble sugars and starch were better fitted by the model when the effects of water content on carbohydrate metabolism were taken into consideration. Water content might play a regulatory role in the carbon metabolism from sugars to compounds other than sugars and starch in Cervil fruit, and from sugars to starch in Levovil fruit. While water content influences tomato fruit carbohydrate concentrations by both metabolism and dilution/dehydration effects in the early developmental stage, it is mainly by dilution/dehydration effects in the late stage. The possible mechanisms underlying the effect of the fruit water content on carbohydrate metabolism are also discussed.

Souty先前提出的糖模型的适应。提出了两种版本的模型，有或不整合水果含水量对碳水化合物代谢的影响，然后用来自两种基因型，Levovil和Cervil的数据集评估，在不同的条件下生长。结果表明，对于碳水化合物对碳水化合物代谢的影响，模型，可以更好地拟合可溶性糖和淀粉。含水量可能在糖中的碳代谢中发挥调节作用，以糖和淀粉的化合物在Cervil水果中的糖和淀粉，并从柳叶果实中的糖到淀粉。虽然水含量影响番茄果实碳水化合物浓度，但在早期发育阶段中的代谢和稀释/脱水作用，它主要通过晚期稀释/脱水作用。还讨论了水果含水量对碳水化合物代谢的影响的可能机制。
