我国是栽培大麦的起源中心之一.我们在对栽培大麦生理生长性状与辐射敏感性关系的基础上设计了本试验.在细胞水平上研究不同类型栽培大麦的辐射敏感性差异.1 材料和方法 试材为24个栽培大麦品种的休眠种子,分属于二棱皮大麦,二棱裸大麦,四棱皮大麦,四棱裸大麦,六棱皮大麦和六棱裸大麦.种子含水量为12％左右。 China is one of the origin centers of cultivated barley.We designed this experiment based on the relationship between physiological growth traits and radiation sensitivity of cultivated barley.The differences of radiation sensitivity of different types of cultivated barley at the cellular level were studied.1 Materials and Methods The tested materials were dormant seeds of 24 cultivated barley varieties, belonging to two types of barley, two-sided naked barley, four-rowed barley, four-row naked barley, six-rowed barley and six- about.
