We investigated dry matter production and fruit characteristics of high-Brix tomatoes when plants were pinched above the third truss and electrical conductivity of the nutrient solution was gradually increased by changing the amounts of nutrients and NaCl. In the salinized treatment, fruit fresh weight was significantly decreased, and fruit Brix was significantly increased, relative to the non-salinized treatment. There were no significant differences in leaf area index, light use efficiency, light intercepted by leaves, total dry matter production, fruit dry weight, or dry matter distribution to fruit between treatments, but dry matter content of fruits was significantly increased in the salinized treatment. Therefore, dry matter production by plants was not reduced by the salinized treatment. The increase in fruit Brix was associated mainly with the increase in the dry matter content of fruits. Without reducing dry matter production, high-brix tomatoes can be produced by controlling the nutrient solution.

我们调查了将植物捏在第三桁架上方并通过改变养分和NaCl的量逐渐增加养分溶液的电导率的高白利糖度番茄的干物质生产和果实特性。在盐渍化处理中，相对于非盐渍化处理，水果鲜重显着降低，而水果白利糖度显着增加。处理之间的叶面积指数，光利用效率，叶片截获的光，总干物质产量，果实干重或果实中干物质分布之间无显着差异，但盐化处理中果实的干物质含量显着增加。 。因此，盐化处理不会减少植物产生的干物质。水果糖度的增加主要与水果干物质含量的增加有关。在不减少干物质产量的情况下，可以通过控制营养液来生产高糖度西红柿。
