| 摘 要： | 采用人工接蜂、桉树组织石蜡切片和生化组分测定等方法研究了桉树受桉树枝瘿姬小蜂诱导后的生理生化响应机制.结果表明:DH201-2叶柄角质层厚度和油囊数量均较GL-UG9的厚、多,且差异均达到极显著水平(P角质层厚度=0.00001 ＜0.01,P油囊数量=0.00209＜0.01),但是GL-UG9叶柄表皮细胞厚度和维管束数量均较DH201-2厚、多,差异分别达到显著水平(P=0.015215＜0.05)和极显著水平(P=0.002375＜0.01),DH201-2茎皮层薄壁细胞厚度、油囊直径、维管束数量较GL-UG9厚、多,差异分别为显著(P皮层薄壁细胞厚度=0.04071 ＜0.05)、极显著(P油囊直径=000016＜0.05)、极显著(P维管束数量=0.00000＜0.01).而GLUG9茎角质层和表皮细胞厚度均较DH201-2厚,差异达到了极显著水平(P角质层厚度=0.00167,P表皮细胞厚度=0.00000＜0.01)；桉树枝瘿姬小蜂虫瘿为组织瘿,由内到外可以分为:营养组织层、薄/厚壁组织层、维管束层、皮层、表皮等结构；接种桉树枝瘿姬小蜂成虫后,桉树叶片可溶性总糖、游离氨基酸、叶绿素含量均升高,差异达到了极显著水平(P＜0.01),但是蛋白质、pH值、类黄酮、总酚的变化没有达到显著水平(P＞0.05)；吲哚乙酸氧化酶、过氧化物、过氧化氢酶活力均有不同程度的升高.研究显示桉树枝瘿姬小蜂入侵诱导了桉树一系列的生理生化变化,实验结果为抗桉树枝瘿姬小蜂桉树无性系的选育技术体系构建提供了理论基础.
