| 摘 要： | 测定马尾松家系中未受松突圆蚧危害植株与受害植株针叶中可溶性糖、总糖、可溶性蛋白、全N、游离氨基酸、粗脂肪等营养物质的含量,探讨营养物质含量与马尾松对松突圆蚧抗性的关系。结果表明:1)高抗家系全N含量低于中抗和低抗家系;2)受松突圆蚧危害的诱导,针叶可溶性糖和总糖含量降低,此诱导反应与家系对松突圆蚧的抗性无关;3)可溶性蛋白、全N含量和游离氨基酸总量也因松突圆蚧的危害而降低,但这一诱导反应与家系对松突圆蚧的抗性有关,高抗家系降低量大于低抗家系,导致高抗家系受害植株中这几类营养物质的含量低于低抗家系;4)高抗家系受害植株针叶中除精氨酸外的16种氨基酸含量低于低抗家系;5)粗脂肪含量和总糖/全N与马尾松对松突圆蚧的抗性无关。 |

| Abstract: | In this study,we determined the content of soluble sugar,total sugar,soluble protein,total nitrogen,free amino acids and crude fat in needles of various masson pine families,which have different resistance to Hemiberlesia pitysophila,to investigate the relationship between this nutrient content and the resistance of masson pines against the scale. The result showed that: 1)The content of total nitrogen in needles of high resistant families was lower than that in middle resistant families and low resistant f... |
