培養(yǎng)基種類與特點(diǎn)

    培養(yǎng)基有許多種類,根據(jù)不同的植物和培養(yǎng)部位及不同的培養(yǎng)目的需選用不同的培養(yǎng)基。培養(yǎng)基的產(chǎn)生zui早是Sacks(1680)和Knop(1681),他們對(duì)綠色植物的成分進(jìn)行了分析研究,根據(jù)植物從土中主要是吸收無(wú)機(jī)鹽營(yíng)養(yǎng),設(shè)計(jì)出了由無(wú)機(jī)鹽組成的Sacks和Knop溶液,至今仍在作為基本的無(wú)機(jī)鹽培養(yǎng)基得到廣泛應(yīng)用。以后根據(jù)不同目的進(jìn)行改良產(chǎn)生了多種培養(yǎng)基,White培養(yǎng)基在40年代用得較多,現(xiàn)在還常用。而到60和70年代則大多采用MS等高濃度培養(yǎng)基,可以保證培養(yǎng)材料對(duì)營(yíng)養(yǎng)的需要,并能生長(zhǎng)快、分化快,且由于濃度高,在配制、消毒過(guò)程中某些成分有些出入,也不致影響培養(yǎng)基的離子平衡。培養(yǎng)基的名稱,一直根據(jù)沿用的習(xí)慣。多數(shù)以發(fā)明人的名字來(lái)命名,如White培養(yǎng)基,Murashige和Skoog培養(yǎng)基(簡(jiǎn)稱MS培養(yǎng)基),也有對(duì)某些成分進(jìn)行改良稱作改良培養(yǎng)基。目前上流行的培養(yǎng)基有幾十種,常用的培養(yǎng)基及特點(diǎn)如下: (1)MS培養(yǎng)基它是1962年由Murashige和Skoog為培養(yǎng)煙草細(xì)胞而設(shè)計(jì)的。特點(diǎn)是無(wú)機(jī)鹽和離子濃度較高,為較穩(wěn)定的平衡溶液。其養(yǎng)分的數(shù)量和比例較合適,可滿足植物的營(yíng)養(yǎng)和生理需要。它的硝酸鹽含量較其他培養(yǎng)基為高,廣泛地用于植物的器官、花藥、細(xì)胞和原生質(zhì)體培養(yǎng),效果良好。有些培養(yǎng)基是由它演變而來(lái)的。(2)White培養(yǎng)基 是1943年由White為培養(yǎng)番茄根尖而設(shè)計(jì)的。1963年又作了改良,稱作White改良培養(yǎng)基,提高了MgSO4的濃度和增加了硼素。其特點(diǎn)是無(wú)機(jī)鹽數(shù)量較低,適于生根培養(yǎng)。(3)B5培養(yǎng)基 是1968年由Gamborg等為培養(yǎng)大豆根細(xì)胞而設(shè)計(jì)的。其主要特點(diǎn)是含有較低的銨,這可能對(duì)不少培養(yǎng)物的生長(zhǎng)有抑制作用。從實(shí)踐得知有些植物在B5培養(yǎng)基上生長(zhǎng)更適宜,如雙子葉植物特別是木本植物。(4)N6培養(yǎng)基是1974年朱至清等為水稻等禾谷類作物花藥培養(yǎng)而設(shè)計(jì)的。其特點(diǎn)是成分較簡(jiǎn)單,KNO3和(NH4)2SO4含量高。在國(guó)內(nèi)已廣泛應(yīng)用于小麥、水稻及其他植物的花藥培養(yǎng)和其他組織培養(yǎng)。 (5)KM-80培養(yǎng)基它是1974年為原生質(zhì)體培養(yǎng)而設(shè)計(jì)的。其特點(diǎn)是有機(jī)成分較復(fù)雜,它包括了所有的單糖和維生素,廣泛用于原生質(zhì)融合的培養(yǎng)。
