| 摘 要： | 在日光温室内,以栽培番茄"辽园多丽"为试验材料,研究了花后20 d无土栽培条件下添加不同浓度NaCl与番茄果实生长发育的关系.结果表明:0.025M NaCl明显促进发育后期番茄果实的生长,产量约提高11.25%;0.05M和0.075M NaCl则抑制果实发育;3种浓度NaCl均可提高可溶性糖、有机酸含量,增加糖酸比,但抗坏血酸含量却随着NaCl浓度的提高而降低.

| Abstract: | The relationship between the added NaCl of different concentration and the development of tomato fruit in the soilless culture was studied with the cultivated tomato 'Liaoyuanduoli' at 20 days after anthesis in the greenhouse.The results showed that 0.025M NaCl promoted the development of tomato fruits in the latter phase significantly and the yield were increased by 11.25%.But 0.05M and 0.075M NaCl inhibited the development of fruit.The three kinds of concentrations of NaCl increased the contents of soluble sugar,the organic acid and the brix-acid ratio of the ripe tomato fruit.On the contrary,the contents of ascorbic acid were lowered with the higher concentration of NaCl. |
