用细胞分裂素喷施受湿害的植物，可抑制植株叶片的叶绿素含量下降，延缓衰老。 - Initiation of somatic cells stimulated by cytokinin , division of the initiated somatic cells and succeeding shoot meristem development are three key steps in the process
细胞分裂素诱导体细胞启动、启动的体细胞进行分裂和由此引发的茎分生组织发育是这一过程中的3个重要步骤。 - Floral organs have been successfully induced from the regenerated floral buds of ffyacinthus orienralis l . by precisely controlling exogenous hormones in the medium . under high concentration of cytokinin and auxin , the regenerated floral bud produces only tepals
以风信子花被片为外植体，通过控制培养基中细胞分裂素和生长素的浓度，可诱导花芽的再生和控制产生花器官的种类，建立起离体花器官定向控制系统。 - 2 hybridization results show that hag1 is specifically expressed in stamens and carpels in vivo ; hag1 mrna was first detected in cultured explants at day 5 in the medium containing high levels of cytokinin and auxin , which could induce floral regeneration in vitro
Rna分子杂交结果表明： hag1特异性地在植株上花的雄蕊和心皮中表达：在高浓度激素培养诱导花芽形成过程中，第5天开始检测到外植体中有该基因的mrna 。 - In this review three approaches in study of the effects of cytokinins on plant senecence are presented : the analysis of endogenous cytokinins during senescence ; the application of exogenous cytokinins ; and the research on transgenic plants with cytokinin biosynthesis or biodegradation genes
主要从3个方面综述了细胞分裂素与植物衰老之间的关系，即： ( 1 )植物衰老过程中内源细胞分裂素含量变化： ( 2 )外源细胞分裂素的影响： ( 3 )转入与细胞分裂素的合成、降解相关的从因对植物衰老产生的影响。 - Bap performed more important function than kt in differentiation of tall fescue embryogenic calli , but better results could be achieved with combination of 2mg / l bap and 0 . 5mg / l kt . at this cytokinin level , 0 . 5mg / l naa was recommended to obtain the highest callus regeneration frequency . plant regeneration could be evidently boosted when embryogenic calli were pre - differentiated on high - osmoticum medium with 60g / l sucrose , and / or when the pre - differentiated compact calli were differentiated on differentiation medium solidified with l0g / l agar
高羊茅胚性愈伤组织分化时， bap的作用要比kt大，但2mg lbap与0 . 5mg lkt配合可获得更佳的效果；在该细胞分裂素水平下，生长素naa用0 . 5mg l ，愈伤组织再生率最高；胚性愈伤组织先在含60g l蔗糖的分化培养基上高渗预分化，以及经高渗预分化后的致密愈伤组织在琼脂浓度为10g l的分化培养基上分化，能明显促进愈伤组织的植株再生；在分化培养基中添加脯氨酸导致愈伤组织再生率下降，但同时有减少白化苗再生的趋势。 - Our results provided direct evidence that pf40 gene play a role in the tissue development , with knockout this gene the lateral buds were not visible . the plant hormones auxin and cytokinin appear to play a major role in controlling this process , therefore , the concertrition of auxin and cytokinin was measured , however , the concentration of the two hormone was variation a little in transgenic plants , but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type . furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants , results showed the pf40 could change both xylary fibers and vessel
进一步的实验发现pf40基因会影响植物侧芽发育的早期，即pf40基因作用在侧芽形成与发育的早期。对转基因谷子的组织切片的分析还表明pf40基因引起不同形式的转基因谷子的维管组织的发育的差异，转化正义载体谷子的木质部变多，维管系统增多，而反义或干扰的转基因谷子的木质部数量变少，木质部分化异常。从转基因的结果可见pf40基因可以减弱植物的顶端优势，这种作用是通过改变植物体内激素的含量实现的。
