They are one new variety of P. longzhouensis (B.Pan & W.H.Wu) W.B.Xu & K.F.Chung, and three varieties of P. sinovietnamica W.H.Wu & Q.Zhang. Simultaneously, the main differences between these four new taxa and their original varieties were discussed respectively, and investigations and analyses were conducted regarding their respective survival status and endangered conditions.展开更多
为探究水松(Glyptostrobus pensilis)叶和枝的营养价值和开发潜力,本研究提取并分析水松叶和枝的基本营养物质、矿质元素和氨基酸含量,并对其氨基酸营养价值进行分析、评价。结果显示:(1)除蛋白质含量为水松枝比叶高外,干物质、灰分、...为探究水松(Glyptostrobus pensilis)叶和枝的营养价值和开发潜力,本研究提取并分析水松叶和枝的基本营养物质、矿质元素和氨基酸含量,并对其氨基酸营养价值进行分析、评价。结果显示:(1)除蛋白质含量为水松枝比叶高外,干物质、灰分、粗纤维、总黄酮、维生素E以及维生素C均为叶中含量较高。(2)叶和枝中均检测出16种氨基酸,其中有7种必需氨基酸。枝的异亮氨酸和亮氨酸含量高于叶。(3)叶的必需氨基酸比值系数分(Score of Ratio Coefficient of Essential Amino Acid,SRC)比枝高,为64.952,表明叶中氨基酸营养价值较枝高。(4)常量元素中的K、Ca、N含量在水松叶和枝中较高,其中Ca的含量在叶和枝中均最高,并且叶的Ca含量高于枝,为7980.00 mg/kg。(5)微量元素中的Al、Fe含量在水松叶和枝中较高,叶中Al、Zn含量均高于枝的含量,分别为19.700和1.180 mg/kg;枝中Fe含量高于叶含量,为26.700 mg/kg。本研究分析了水松叶和枝中营养成分的特点,为水松作为木本饲料和水松衍生产品开发提供了基础资料。展开更多
