摘　　要：对蒙农红豆草和缘毛雀麦在不同贮藏年限的种子活力和营养成分变化规律进行了探讨。结果表明:贮藏10年间的蒙农红豆草种子发芽率为18.5%～86.0%,粗蛋白(23.78%～28.06%)、粗脂肪(2.00%～2.42%)、粗纤维(18.06%～19.64%)、粗灰分(4.82%～8.41%)、无氮浸出物(46.02%～47.67%),随贮藏年限的延长大体上呈现下降趋势。贮藏11年间的缘毛雀麦种子发芽率为4.25%～68.50%,粗蛋白(12.65%～14.05%)、粗脂肪(1.60%～1.92%)、无氮浸出物(64.84%～65.92%)含量在各年度间的变化无规律;粗纤维(13.79%～15.18%)和粗灰分(4.65%～5.09%)没有显著变化(p<0.05)。在本试验保存条件下,蒙农红豆草和缘毛雀麦种子分别能维持7～8年和6～7年的种用价值,当失去种用价值(发芽率下降至50%)后,仍具有较高的营养价值。The thesis studied on the seed vigor and nutritive composition of Onobrychis viciifolia scop.cv.Mengnong and Bromus ciliatus L.in different storage years.The results showed that the germination rate of Onobrychis vicifolia scop.cv.Mengnong was changed from 18.5% to 86.0% during 10 storage years,Crude protein contents（23.78%-28.06%）,Crude fat（2.00%-2.42%）,Crude fiber（18.06%-19.64%）,Crude ash（4.82%-8.41%）,and N-free extract contents（46.02%-47.67%） had decreased on the whole among these years.The germination rate of Bromus ciliatus L.was changed from 4.25% to 68.50% during 11 storage years,Crude protein（12.65%-14.05%）,Crude fat（1.60%-1.92%） and N-free extract contents（64.84%-65.92%） were not objective regulation among these years.The variation of Crude fiber（13.79%-15.18%） and Crude ash（4.65%-5.09%） had no significant change（p0.05）.In the present experiment preserved condition,Onobrychis viciifolia scop.cv.Mengnong could keep the seed planting value from 7 to 8 years,and Bromus ciliatus L.could be kept from 6 to 7 years.Moreover,two kinds of seeds still had high nutritional value when they lost planting value（germination rate down to 50%）.
