薇甘菊 草本植物 木本植物 光合能力 反射率 透射率
2009/11/18
该文对薇甘菊及其所在群落内19种植物(草本和木本)的叶片透射率、反射率和光合特征指标进行了测定, 结果表明:薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近, 在各个光学特征指标与光合相关指标的相互关系中, 薇甘菊并没有表现出区别于同一群落内其它植物的特征。从平均值来看, 200-800 nm下叶片反射率和透射率由大到小依次为: 薇甘菊>草本植物>木本植物, 薇甘菊各光学植被指标(SR680、S...
改良CTAB法用于多年生植物组织基因组DNA的大量提取--An Efficient Macro-method of Genomic DNA Isolation from Actinidia chinensis Leaves
猕猴桃 DNA 提取 Southern杂交 Actinidia genomic DNA isolation Southern blot
2007/12/5
根据多年生植物组织富含多酚、多糖的具体特性，对现有的DNA提取方法进行了改进。通过增加提取缓冲液中b-巯基乙醇用量，简化氯仿/异戊醇抽提液步骤，改用经-20℃预冷异丙醇沉淀DNA等，对CTAB法加以改进。改进后方法具有以下优点：（1）获得的DNA质量良好，提取过程无明显的DNA降解，基本上排除了多酚物质的干扰；（2）用获得的DNA进行Southern杂交，可得到理想的杂交信号，可满足相关的分子研究...
