柚,屬喬木,原產自東南亞,大約在公元前1000年引進中國,柚子喜溫熱,初到中華大地,便愛上了南方的這片“熱土”。歷經千年,如今長江以南各地都能見到柚子的身影。
柚子是我們日常常見的一種水果,不光味道鮮美,更可以起到清熱解毒、止咳平喘、消食化氣的作用,是廣大老百姓喜愛的水果之一。而我們在購買的時候,會發現有個頭大的,個頭小的,有的柚子甜,有的柚子則帶有苦味,這都與柚子的生長種植有關!
這個季節是病蟲草害的旺發高峰期,也是柚子的生長發育的關鍵期,果實品質要想有一個更大的提升,這個時候的管理非常重要。特別是病蟲害頻發的話,那就會直接影響到果實的品質。柚子有4種不常見的病害:主要是瘡痂病、流膠病、膏藥病和煤煙病。危害癥狀有:危害葉片、主干和主枝,受害葉片嚴重時失去光彩,呈灰白色,引起落葉、枯梢。嚴重影響光合作用,造成樹勢衰退,產量下降和品質降低等。
要提高柚子的產量及品質,科研人員也希望在柚子的葉片莖中得到答案,在前處理上使用凈信Tissuelyser-24L多樣品組織研磨儀。
這款儀器適用于各種植物組織包括根、莖、葉、花、果、種子等樣品的研磨破碎;是一種特殊的、快速的、高效率的、多試管的一致系統。它能將任何來源(包括土壤、植物和動物的組織/器官、細菌、酵母、真菌、孢子、古生物標本等)的原始DNA、RNA和蛋白質進行提取和純化。
性能特點:
1.穩定性好:采用垂直振蕩方式,研磨更充分,穩定性更好;
2.效率高:1分鐘內完成2×24、2×48、4×96個樣品的研磨;
3.重復性好:同一組織樣本設定相同程序,獲得相同的研磨效果;
4.操作簡便:內置程序控制器,可對研磨時間、轉子的振動頻率等參數進行設置;
5.安全性高:具備安全罩及安全鎖;
6.無交叉污染:在研磨過程中處于全封閉狀態,避免交叉污染;
7.低噪音:儀器運行過程中,噪音小于55dB。
實驗步驟:
實驗材料:柚子葉片莖,
1.將有機材料剪成小塊放入若干毫升離心管中,
2.加入若干毫升RNA裂解液,
3.研磨儀設置參數并啟動。
柚子要管理栽培得當才會碩果累累!
