In this study, we investigated the effect of salinity on photosynthesis and the distribution of photosynthates in the Japanese tomato (Solanum lycopersicum) cultivar ‘CF Momotaro York’ and the Dutch cultivar ‘Endeavour’. Although significant differences were not observed in fresh yield among the cultivars, there were significant differences between the control and salinity in terms of fresh yield, total soluble solids, and titratable acid. The total dry weight in the Japanese cultivar was not affected by salinity, but the Dutch cultivar had lower total weight under salinity compared to the control. Regarding dry mass partitioning, the Japanese cultivar had a lower dry mass ratio of vegetative organs and a higher ratio of fruits than the Dutch cultivar. Salinity did not affect the photosynthetic rate in the Japanese cultivar, but did affect the Dutch cultivar, possibly due to water use efficiency. These results indicate that this Japanese cultivar has characteristics of efficient fruit production under a low node-order pinching and high-density planting system, even under salinity conditions.

在这项研究中，我们研究了盐度对日本番茄（Solanum lycopersicum）光合作用和光合产物分布的影响。）品种'CF Momotaro York'和荷兰品种'Endeavour'。尽管在各品种之间未观察到新鲜产量的显着差异，但对照和盐度之间在新鲜产量，总可溶性固形物和可滴定酸方面存在显着差异。日本品种的总干重不受盐度的影响，但是与对照相比，荷兰品种在盐度下的总重较低。关于干物质分配，日本品种的营养器官的干物质比率较低，而水果的比率则高于荷兰品种。盐度不会影响日本品种的光合速率，但会影响荷兰品种，这可能是由于水分利用效率所致。
