摘要
对来源于中国13个省（区）1010份和国外引进的4份裸燕麦品种（系）进行了β-葡聚糖含量的鉴定研究。结果表明，中国裸燕麦β-葡聚糖含量为2．0％～7．5％，其中含量〈3．00％的占6．61％，3．00％～4．99％的占86．4％。5．00％～5．99％的占5．72％，≥6．00％的占1．18％。按品种类型划分，地方品种的含量低于育成品种（系）。按来源地划分，河北、山西、内蒙古的含量较高，云南、贵州、四川的含量较低，而陕西的含量最低。同年不同地点或相同地点不同年份种植的相同品种（系），含量有一定的变化（0．27％～0．83％）。在鉴定中筛选出一批高β-葡聚糖品种（系）。本研究不仅为燕麦高β-葡聚糖育种提供了理论依据和物质基础，而且为降脂燕麦保健片的生产提供了优良品种。
The β-glucan content of naked oat was analysed and evaluated for 1010 accessions from 13 provinces in China and 4 exotic accessions. The result showed that the β-glucan contents ranged from 2.0 % to 7.5 % by dry weight of sample. The β-glucan content of 6.6% cultivars was bellow 3% in the total cutivars analysed, 86.5 % ranged from 3.00 % to 4.99 %, 5.7 % from 5.00 % to 5.99 %, and 1.2 % was 6 % or above. According to the types of eultivars, the β-gluean content of landraces was lower than breeding eutivars. The β- glucan contents in oat from Hebei, Shanxi, Inner Mongolia were high, from Yunnan,Guizhou, Siehuan were low, and was from shaanxi lower. The β-glucan contents of the same cultivavs varied from 0.27 % to 0.83 % in different locations in the same year and in the same location in different years respectively. A batch of cultivers with higher β-glucan content were screened. This study not only provided theoretical and material basis for the breeding of oat with high β-glucan content, but also good variety for production of hypocholesterolemie and healthful oatmeal.
