摘　　要：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300mg/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256.67~319.53mg/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125g/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196.18~205.14mg/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维生素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 reynaudiana and Sorghum halepense contained the highest vitamin C in the stem,more than 300 mg/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 arundinaceum,P.purpureum typhoideum,Andropogon gayanus had a leaf vitamin C content ranging from 256.67 to 319.53 mg/kg;S.halepense and Neyraudia reynaudian had the highest leaf soluble saccharides content,about 125 g/kg.Pennisetum americanum×P.purpureum and S.halepense contained the highest vitamin C in leaf sheath,ranging from 196.18 to 205.14 mg/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.
