| 摘 要： | 比较了江苏省主栽的粳稻品种 (南农 4号、南粳 39、镇稻 99和扬粳 6 87)的糙米发芽力及发芽期间主要物质含量差异。结果表明 ,糙米的发芽力、呼吸速率和淀粉酶活力以及淀粉等贮藏物质的降解速度因粳稻品种不同而异 ,其中以南农 4号发芽率最高 ,淀粉降解速度快 ,还原糖、水溶性蛋白质和游离氨基酸含量大。四个粳稻品种的糙米发芽势与淀粉酶活力、主要物质含量之间呈显蓍的相关性

| Abstract: | Four short-grain rice(Japonaca)varieties,i.e.Nannong No.4,Nanjing 39,Zhendao 99,and Yangjing 687,planted in Jangsu province were used to investigate the germinating energy of brown rice and the essential substance change during the germination.It is indicated that the germinating energy,respiratory rate,amylase activity,and degradation velocity of storage substance such as starch are different among the four rice varieties.Nannong No.4 shows the highest germinating energy and the fastest starch degradation,and consequently has the highest contents of reducing sugar,water-soluble protein and free amino acids in germinated brown rice.The brown rice germinating energy is strongly correlative with the amylase activity for the four rice varieties. |
