【摘要】 对17份山蚂蝗材料营养期的营养成分进行测定与分析。结果表明:(1)粗蛋白含量最高的为CIAT3787(D.hererocarpum)(22.34%),其次是CIAT46562(D.dunniinicaraguense)(22.32%);粗纤维含量最高的是CIAT13218(D.velutinum)(38.70%),显著高于其他品系(p>0.05);(2)山蚂蝗营养成分之间存在不同程度的相关性,粗纤维含量分别与粗灰分、无氮浸出物、磷的含量存在极显著负相关,粗灰分含量与磷含量有极显著正相关,与钙含量有显著相关;(3)通过聚类分析,在欧氏距离8.0处,可将17份供试山蚂蝗材料划分为3类,其中CIAT46562和CPI46561(D.incanum)单独聚为一类。更多还原

【Abstract】 The nutritional components of 17 Desmodium Desv. accessions were studied at vegetative stage. The results indicated that CIAT3787(D. hererocarpum) had the hightest CP(22.34%),and the next was CIAT46562(D. dunniinicaraguense)(22.32%). CIAT 13218(D. velutinum) had the highest CF(38.70%),and significantly higher than other accessions. Nutritional components of Desmodium Desv. had different degree of correlation coefficient. CF with Ash,NFE and P had extremely significant(p <0.01) negative correlation. Ash with P had extremely significantly positive correlation(p <0.01),with Ca had significantly positive correlation(p <0.05). Based on nutritional components,the accessions were clustered into three groups. CIAT46562 and CPI46561(D. incanum)all solely were a group.更多还原
