为了对珍珠龙胆石斑鱼的营养品质进行评价,利用常规方法对养殖珍珠龙胆石斑鱼肌肉和鱼皮的氨基酸、脂肪酸以及肌肉、鱼皮和肝脏的矿物质组成进行测定.结果 表明珍珠龙胆石斑鱼肌肉和鱼皮中含有16种氨基酸,总量分别19.58％和25.03％;必需氨基酸分别为7.38％和6.39％,占氨基酸总量分别为37.69％和25.53％.珍珠龙胆石斑鱼肌肉和鱼皮的脂肪酸含量关系为Saturated fatty acid＞Monounsaturated fatty acid＞Polyunsaturated fatty acid SFA分别占脂肪酸总量51.72％,72.37％;MU-FA分别占脂肪酸总量33.05％,17.80５;PUFA分别占脂肪酸总量15.35％,9.02％.珍珠龙胆石斑鱼肌肉矿物质含量高低顺序为:K＞ Na＞ Ca＞ Mg＞ Zn＞ Fe＞ Cu＞ Mn;鱼皮矿物质含量高低顺序为:Ca＞Na＞K＞Mg＞Zn＞Fe＞Cu＞Mn;肝脏矿物质含量高低顺序为:K＞Na＞ Fe＞Ca＞ Mg＞ Zn＞ Cu＞ Mn;但是按照Hill和Matron提出的“理化性质相似的元素”,龙胆石斑鱼的铜、铁、锌的比值不合理.

本试验以经我校改良的育性稳定的小麦细胞质不育系和保持系及其温敏不育系和恢复系为材料,开展了繁殖制种体系及其可恢复性和杂种优势研究,结果如下:1赤霉素敏感品系的筛选要提高细胞质不育系的繁殖产量和杂交制种产量,就必须使父本和母本有一定的株高差。然而,细胞质不育系繁殖时,父本和母本株高相等;制种过程中,也会遇到恢复系与不育系株高相近的问题。本研究以56个优良小麦品系为材料,采用外施赤霉素的方法以增加其株
