Cotyledon and true leaves of stem mustard were cultured on ms medium supplemented with different concentrations of various cytokinins ( ba , cppu , tdz or kt ) alone or in combination with naa or iba , and the adventitious buds regeneration rate was evaluated . 以榨菜子叶、真叶为外植体进行离体培养,用ba 、 cppu 、 tdz和kt等细胞分裂素和生长素naa 、 iba组合诱导子叶、真叶再生不定芽试验。
A phenomenon of " specialization for abundance " might occur in both photosynthetic ramets and adventitious roots during the clonal growth of s . vulgaris , and it was a kind of clonal behavior of labor division , which was benefit to the genet to using heterogeneous resources 克隆整合作用对维持遭受干扰后分株的存活有重要作用。臭柏通过光合分枝和不定根的“趋富特化”克隆分工行为,提高对异质性资源的利用能力。
Adventitious shoots could be rooted and formed regenerated plants on 1 / 2 ms medium supplemented with naa0 . 4mg / l . hairy roots could be induced from the basal surface of the explants 8 days after inoculation of a . ficoidea cv . " ruliginosa " leaf explants with a . rhizogenes atcc 15834 红龙草叶片外植体被发根农杆菌atcc15834感染8d后,从形态学下端叶脉处陆续分化出乳白色的不定根, 21d后,叶片外植体的生根率高达92 . 5 。
High sucrose and agar is apt to keep the tight close structure of callus . ( 4 ) the optional inducing medium of adventitious buds is ms basal medium with 2mg / l 6 - ba , 30g / l sucrose and 9g / l agar . all the tested genotypes have high inducing rate on this medium 供试的4个基因型在此培养基上不定芽诱导效率均最高,由高到低依次为:松93 - 8为962 . 9 ;东农v10为679 . 7 ;东农419为542 . 5 ;富士光为482 . 6 ,与其它处理差异达到显著。
Malonaldehyde , a marjor product of the peroxidation of polyunsaturated lipids , may play an essential role in the formation of the fluorescent products in lipofuscin - like fluorescent pigments and in the blood viscosity increase . fluorescence and non - enzymatic browning were observed in reactions between ascorbic acid ( asa ) and amino acids ( aa ) as well as in reactions involving asa autoxidation and / or polymerization in the presence of trace amounts of adventitious iron 在同时进行的荧光测定中,我们发现,丙二醛( 20mm )能迅速地降低蛋白溶液的典型荧光( 280nm 350nm ) ,而就此产生在395nm的波长激发下,发射出波长为460nm的荧光,造成蛋白质的变构变性。
S . regeneration system of mustard hypocotyls and cotyledons of 4 days and leaves of 25 days were used as transformation materials , and ms as basic medium supplying different ba ^ naa and kt concentration , we got the optimum explant adventitious bud inducing medium ( ms + 6 - ba3 . 0mg / l + naa0 . 2 mg / l ) . among the three kinds of mustard explants . the cotyledons showed the highest adventitious bud regeneration capacity . and the regeneration capacity of leaf explantswas weaker . and the weakest of hypocotyls 芥菜高频再生体系的建立以4天左右的叶用和茎用芥菜子叶、下胚轴和25天苗龄的芥菜无菌苗的叶片为外植体,以ms为基本培养基,通过加入不同浓度和不同组合的ba 、 naa 、 kt ,筛选到了外植体不定芽分化的最适培养基( ms + ba3 . 0mg / l + naa0 . 1mg / l )及生根的最适培养基( ms + naa0 . 2mg / l ) 。
Because of working property or the limitation that produce a characteristic , cannot implement standard man - hour system , need executes the enterprise of the duty when adventitious and integrated computation duty , should deal with examine and approve formalities , newspaper proprietor of an enterprise is in charge of sectional examine and verify , labor ensures service approval 因工作性质或生产特点的限制,不能实行标准工时制度的,需要实行不定时工作制和综合计算工作制的企业,应办理审批手续,报企业主管部门审核,劳动保障行政部门批准。
The regeneration system of tobacco was established . the adventitious shoots were induced from leaf explants of tobacco based on ms basal medium supple - - mented with 2 . 0mg / l 6 - ba and 0 . 3mg / l naa . then the regenerated plants were rooted on ms medium containing 0 . 3mg / l naa 植株再生体系的建立采用无菌苗烟草叶片为外植体,以ms为基本培养基,筛选出ms + 6 - ba2 . 0mg l + naa0 . 3mg l以诱导不定芽的分化,并于ms + naa0 . 3mg l的pa硕士学位论文v沉了砂“工队nk ”主根培养基上生根,获得完整再生植株。
I am sure most people would have thought him an ugly man ; yet there was so much unconscious pride in his port ; so much ease in his demeanour ; such a look of complete indifference to his own external appearance ; so haughty a reliance on the power of other qualities , intrinsic or adventitious , to atone for the lack of mere personal attractiveness , that , in looking at him , one inevitably shared the indifference , and , even in a blind , imperfect sense , put faith in the confidence 我敢肯定,大多数人都认为他是个丑陋的男人,但是他举止中却无意识地流露出那么明显的傲慢,在行为方面又那么从容自如,对自已的外表显得那么毫不在乎,又是那么高傲地依赖其他内在或外来的特质的力量,来弥补自身魅力的缺乏。因此,你一瞧着他,就会不由自主地被他的漠然态度所感染,甚至盲目片面地对他的自信表示信服。
associated by chance and not an integral part; "poetry is something to which words are the accidental, not by any means the essential form"- Frederick W. Robertson; "they had to decide whether his misconduct was adventitious or the result of a flaw in his character"
