A quick DNA extraction technique which was fitting for maize variety identification and establishing DNA fingerprinting pool was explored ,and the technique was well applied in the following tissues for DNA extraction : embryo, endosperm; radicel, coleoptile , hypocotyl from germinated 1～3 days material .

本实验探索了适用于玉米品种鉴定及DNA指纹库构建的玉米品种DNA快速煮沸法，用快速煮沸法提取了玉米种子胚、胚乳；水培初生根、侧根；种子出苗后的初生根、侧根、胚芽鞘、胚轴、叶片等组织DNA，结果表明，种子胚、胚乳组织；水培2～4d水培初生根、侧根组织；出苗1～5d的胚芽鞘、胚轴组织用快速煮沸法提取DNA效果较好。

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.

研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

The author cites several instances to explain why the liberalization of teacher education shouldn't end in the first level of marketing orientation, namely,"marketization", and rather advances to the second level of marketing-"consumer orientation" marketing. Borrowing from the term "blue sea strategy", the author argues that the institutes of teacher education, including the normal universities and teacher colleges, have to look for the unique and appropriate strategies to sustain the advantageous position of teacher education.
