对18种饲用禾本科植物的叶片、叶鞘、茎杆的维生素C和可溶性糖含量进行测定与分析.结果表明:类芦、石茅茎秆维生素C含量最高,达300 mg/kg以上,与其余供试植物茎秆维生素C含量差异显著;青香茅茎秆可溶性糖含量较高,与其余供试植物茎秆可溶性糖含量差异显著.石茅、矮象草、斑茅、王草、甘巴草叶片维生素C含量在256.67～319.53 mg/kg之间,与其余供试植物叶片维生素C含量差异显著;石茅、类芦叶片可溶性糖含量最高,在125 g/kg左右,与其余供试植物叶片可溶性糖含量差异显著.杂交狼尾草、石茅叶鞘维生素C含量最高,在196.18～205.14 mg/kg之间,与除菅外的与其余供试植物叶鞘维生素C含量差异显著;甜根子草叶鞘可溶性糖含量最高,与其余供试植物叶鞘可溶性糖含量差异显著.18种植物不同部位之间雏生素C含量有明显区别;除石芒草外其余供试植物的不同部位之间可溶性糖含量差异显著,除青香茅外其余供试植物的可溶性糖含量呈现叶片>叶鞘>茎秆的趋势.

The contents of vitamin C and soluble saccharides in leaves, leaf sheaths and stems of 18 species of forage grasses were determined. Neyraudia reynaudian,a and Sorghum, halepense contained the highest vitanun C in the stem, more than 300mg/kg, significantly higher than the other species determined;Cymbopogon caesius contain higher soluble saccharides, obviously higher than the other species. S.halepense, Pennisetum purpureum, Saccharum arundinceum, P. purpureum typhoideum, Andropogon, gayanus had a leaf vitamin C content ranging from 256.67 t0319.53mg/kg;S.halepense and Neyraudia reynaudian had the highest leaf soluble saccharides content, about 125 g/kg. Pennisetum americanum×P. pzupureum and S. halepense contained the highest vitamin C in leaf sheath, ranging from 196.18 to 205.14mg/kg;Saccharum spontaneum contained the highest soluble saccharides in leaf sheath. All the 18 species of forage grasses were evidently different in vitamin C content between organs, and their soluble saccharides content except that of Cymbopogon, caesius tended to decreased in the order of leaf>leaf sheath>stem.
