柚,属乔木,原产自东南亚,大约在公元前1000年引进中国,柚子喜温热,初到中华大地,便爱上了南方的这片“热土”。历经千年,如今长江以南各地都能见到柚子的身影。
柚子是我们日常常见的一种水果,不光味道鲜美,更可以起到清热解毒、止咳平喘、消食化气的作用,是广大老百姓喜爱的水果之一。而我们在购买的时候,会发现有个头大的,个头小的,有的柚子甜,有的柚子则带有苦味,这都与柚子的生长种植有关!
这个季节是病虫草害的旺发高峰期,也是柚子的生长发育的关键期,果实品质要想有一个更大的提升,这个时候的管理非常重要。特别是病虫害频发的话,那就会直接影响到果实的品质。柚子有4种不常见的病害:主要是疮痂病、流胶病、膏药病和煤烟病。危害症状有:危害叶片、主干和主枝,受害叶片严重时失去光彩,呈灰白色,引起落叶、枯梢。严重影响光合作用,造成树势衰退,产量下降和品质降低等。
要提高柚子的产量及品质,科研人员也希望在柚子的叶片茎中得到答案,在前处理上使用威九国际Tissuelyser-24L多样品组织研磨仪。
这款仪器适用于各种植物组织包括根、茎、叶、花、果、种子等样品的研磨破碎;是一种特殊的、快速的、高效率的、多试管的一致系统。它能将任何来源(包括土壤、植物和动物的组织/器官、细菌、酵母、真菌、孢子、古生物标本等)的原始DNA、RNA和蛋白质进行提取和纯化。
性能特点:
1.稳定性好:采用垂直振荡方式,研磨更充分,稳定性更好;
2.效率高:1分钟内完成2×24、2×48、4×96个样品的研磨;
3.重复性好:同一组织样本设定相同程序,获得相同的研磨效果;
4.操作简便:内置程序控制器,可对研磨时间、转子的振动频率等参数进行设置;
5.安全性高:具备安全罩及安全锁;
6.无交叉污染:在研磨过程中处于全封闭状态,避免交叉污染;
7.低噪音:仪器运行过程中,噪音小于55dB。
实验步骤:
实验材料:柚子叶片茎,
1.将有机材料剪成小块放入若干毫升离心管中,
2.加入若干毫升RNA裂解液,
3.研磨仪设置参数并启动。
柚子要管理栽培得当才会硕果累累!
