沙棘是一种非豆科固氮植物。其蛋白的定性定量评价显示,除了海拔2530~3350m间的种类M-8以外,具有结节的植物普遍比没有结节的植物具有更高的蛋白质含量。在17个沙棘种类的叶、果实、种子中蛋白质水平随着海拔高度的变化在9.65到21.07mg/g鲜重之间变化。其中种子为1.62~5.11mg/g,果实中为0.68~3.51mg/g。数据显示,叶中硝基还原酶活性与蛋白含量存在正相关关系。在海拔较低的Ladakh地区(2500~2850 m)发现的种类(M-2,8,13)比海拔高于2850 m的种类具有更高的蛋白质含量(12.38~15.10 mg/g鲜重),此外,在河畔生长的品种比丘陵斜坡上生长的种类蛋白含量更高。这暗示在荒芜的Ladakh地区,这种沙棘叶可能为人或动物提供多样的食物供给。可以鼓励农业或商业种植沙棘用于饲料。
Seabuckthorn is a non-legume nitrogen fixing plant. Qualitative and quantitative evaluation of their proteins showed that, except for species M-8 at altitudes between 2530 and 3350 m, nodules generally had higher protein content than nodules-free plants. The protein level of leaves, fruits and seeds in 17 seabuckthorn varieties varied with the altitude from 9.65 to 21.07 mg / g fresh weight. The seeds were 1.62 ~ 5.11mg / g, the fruit was 0.68 ~ 3.51mg / g. The data show that there is a positive correlation between nitrate reductase activity and protein content in leaves. The species (M-2,8,13) found in the lower Ladakh region (2500-2850 m) had higher protein content (12.38-15.50 mg / gw) than those at 2850 m above sea level, In addition, species grown on riverside hills had higher levels of protein than those grown on slopes. This suggests that in the barren Ladakh region, the seabuckthorn leaves may provide a variety of food supplies for humans or animals. Seabuckthorn is encouraged to be used for feed, either agricultural or commercial.
