摘要: 正常供钙下 ,不同番茄品种幼苗的吸钙量有较大差异 ,白果强丰 >佳粉 2号 >合作 90 3>江蔬 1号。缺钙培养使番茄幼苗干物质积累和吸钙量下降 ,合作 90 3和白果强丰的干物质量下降程度高于江蔬 1号和佳粉 2号 ,白果强丰的吸钙量降为CK的 9% ,江蔬 1号降为CK的 33%。在CK和缺钙培养中 ,幼苗的老叶含钙量均高于根、茎、幼叶和中位叶 ,但在缺钙培养中 ,中位叶和幼叶的含钙量下降幅度高于根和茎 ;各部位吸钙量CK为中位叶>老叶 >茎 >根 >幼叶 ,缺钙培养后老叶 >中位叶 >茎 >根 >幼叶 ,各部位吸钙量占整株吸钙量之比的变化趋势与此相同。品种间对钙的敏感性比较表明 ,白果强丰对缺钙最敏感 ,合作 90 3次之 ,佳粉 2号和江蔬 1号最不敏感

Abstract: Four tomato cultivars, Baiguoqiangfeng, Jiafen, Hezuo 903 and Jiangshu No.1 were studied on Ca uptake and transportation in the plant at the seedling stage in the condition of Ca deficiency by using solution culture. The results showed that the amounts of the absorbed Ca by seedlings under the normal supplement of calcium (CK) were significantly different among the four cultivars, the detailed order from large to small is as follows: Baiguoqiangfeng, Jiafen, Hezuo 903 and Jiangshu No.1. The absorption of Ca...
