摘要
通过在江西红壤区引种的１６个籽粒苋品种对比试验，分析表明：Ｋ１１２、Ｒ１０４、Ｄ８８－１、Ｍ７、Ｋ４７６、Ｋ３５０、Ｋ４７２、Ｋ４０９、Ｒ１５８等品种表现出较好的生长适应性和稳定性；籽粒苋的鲜茎叶产量与株高、地径、分枝数、叶片数线性相关极显著，且以地径关系最为密切；产籽量与株高、地径、穗长、穗重的相关也极显著，且以穗重最为密切；种子千粒重与穗长、穗重、单株产籽量无显著相关性，且发芽率与千粒重、单株产籽量也无显著相关性，但与温度关系密切，４０～６５℃的温水浸种能提高发芽率。
The contrast tests on 16 varieties of Grain amaranth introduced to red soil areas in Jiangxi Province were carried out. The varieties of K112R104D88-1M7K476K350K472K409R158show their good adaptability. Grain amaranth leaf and stem output linearly related with its heightbasal diameterbranch amount and leaf amount extremely significantly and the relation with basal diameter is the closest. Its seed output is related extremely significantly with its height, basal diameter, tassel's length, tassel's weight and the relation with tassel's weight is the closest. There is no significant relation between its thousand-grain-weight and its tassel's length, tassel's weight,seed output per plant. There is no significant relation between its germination percentage and thousand-grain-weight as well as its seed output per plant. But the germination percentage is closely related with temperature. Soaking seeds in water of 4065 can increase germination percentage.
