| 摘 要： | 用甲醇胁迫，高温高湿等加速老化法，鉴定了１０个栽培大豆和野生大豆品种的抗种子劣变性，结果表明，人工老化后，各野生大豆品种仍保持较高的种子活力，而栽培大豆的种子活力下降较快，电镜观察发现，野生大豆的种皮栅状细胞排列紧密，细胞层厚度大大高于栽培大豆，种皮发芽孔小于栽培大豆，这正是野生大豆高抗种子劣变的原因所在。

| Abstract: | The resistances to seed deterioration of 10 soybean and wild soybean genotypes were tested by methods of methanol stress, high temperature and humidity accelerated aging. The result indicated that seeds of all of five wild soybean genotypes keeped higher vigors than seeds of soybean genotypes. Observations by electron microscope showed that there are thicker, more tightly ranged palisade cells and smaller germpores on seedcoats of wild soybean genotypes than that of soybean genotypes. It is why wild soybean genotypes have higher resistance to seed deterioration than cultivated soybean genotypes. |
