柚,屬喬木,原產(chǎn)自東南亞,大約在公元前1000年引進(jìn)中國,柚子喜溫?zé)?,初到中華大地,便愛上了南方的這片“熱土”。歷經(jīng)千年,如今長江以南各地都能見到柚子的身影。
柚子是我們?nèi)粘3R姷囊环N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(fā)現(xiàn)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(guān)!
這個季節(jié)是病蟲草害的旺發(fā)高峰期,也是柚子的生長發(fā)育的關(guān)鍵期,果實(shí)品質(zhì)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(fā)的話,那就會直接影響到果實(shí)的品質(zhì)。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(yán)重時失去光彩,呈灰白色,引起落葉、枯梢。嚴(yán)重影響光合作用,造成樹勢衰退,產(chǎn)量下降和品質(zhì)降低等。
要提高柚子的產(chǎn)量及品質(zhì),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(tǒng)。它能將任何來源(包括土壤、植物和動物的組織/器官、細(xì)菌、酵母、真菌、孢子、古生物標(biāo)本等)的原始DNA、RNA和蛋白質(zhì)進(jìn)行提取和純化。
性能特點(diǎn):
1.穩(wěn)定性好:采用垂直振蕩方式,研磨更充分,穩(wěn)定性更好;
2.效率高:1分鐘內(nèi)完成2×24、2×48、4×96個樣品的研磨;
3.重復(fù)性好:同一組織樣本設(shè)定相同程序,獲得相同的研磨效果;
4.操作簡便:內(nèi)置程序控制器,可對研磨時間、轉(zhuǎn)子的振動頻率等參數(shù)進(jìn)行設(shè)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(tài),避免交叉污染;
7.低噪音:儀器運(yùn)行過程中,噪音小于55dB。
實(shí)驗步驟:
實(shí)驗材料:柚子葉片莖,
1.將有機(jī)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(shè)置參數(shù)并啟動。
柚子要管理栽培得當(dāng)才會碩果累累!
