Abstract:本实验运用单克隆抗体PAP法,对实验感染鸭肝炎病毒雏鸭的组织切片进行染色观察,旨在动态研究病毒在雏鸭体内的分布以及病毒与组织病变的关系。研究结果显示,感染后3h,雏鸭心肌、肝、脾、肾、胰、腿部肌肉、大脑等组织的细胞浆内均出现了PAP染色的特异性棕黄色产物,除胰脏组织切片的PAP反应性在感染后168h达到最高外,上述其他组织的最高PAP反应性均在感染后24h;对同期的不同组织切片比较观察发现,肝、脾、胰外分泌腺、肾小管上皮细胞及腿部肌肉细胞的PAP反应性比心肌及大脑神经元细胞的PAP反应性强。由此表明,鸭肝炎病毒在感染后3h达全身化,并主要侵害肝、脾、肾、胰及腿部肌肉,继而引起相应的变化

Abstract:通过甘蓝型油菜×白菜型油菜种间杂交和6个世代的鉴定选择,培育了甘蓝型复果油菜90-12和白菜型复果油菜92-16。对500株以上群体抽样调查结果表明:它们的复果株率达100%,单株复果率达40%以上。尽管复果油菜的角果长度、每果粒数和千粒重随着果柄上结角数目增加而减少,但由于复果油菜的单株角果数比普通油菜多33.20%~56.55%,从而使复果油菜的单株产量较普通油菜增加29.38%~35.26%。甘蓝型油菜复果性状由3对隐性核基因控制,但在甘白种间杂种1代表现母性遗传特性

Abstract:通过调查,采集,鉴定,发现竹山青死者杨上有纺锤形,长枣形,小枣形及佛手形4种倍手和肚倍蚜,红小铁枣蚜及佛手倍蚜3种倍蚜,其中纺锤形与长枣形是主要类型,且均由肚倍蚜致瘿成倍,但2种倍子在不同地区的分布比例是不同的。小枣形倍子内的致瘿蚜虫经鉴定为红小铁枣蚜,佛手形倍子是由一倍蚜新种致瘿形成的。

Abstract:在土壤含热水溶性硼为0.09mg/kg(-B)与外加硼至1.0mg/kg(+B)的条件下,盆栽70个陆地棉(GiosypiumhirsutumL)品种,以检验品种间对缺硼敏感性差异。结果表明,70个品种的地上部干物重敏感系数(-B/+B×100)为26.6~102之间。如以其干物重敏感系数小于50为缺硼敏感品种,大于90为不敏感品种,获得敏感品种3个,不敏感品种5个。在缺硼条件下叶片硼效率(单位硼所产生的干物重)与缺硼敏感系数相关性达5%水准,不敏感品种硼效率高,敏感品种硼效率低。但无论缺硼与否,吸硼量与缺硼敏感性之间没有明显相关
