漾濞核桃叶片基因组DNA的两种提取方法效果比较

Comparison on Effect Between Two Methods of DNA Extraction from Leaves of Juglans sigillata

以漾濞核桃不同生长期的叶片为材料，采用高盐低pH法和改良CTAB法作提取其基因组DNA的效果比较实验。

Using the leaves of walnut Yangbi variety ( Juglans sigillata ) of different growing stage as the experimental materials , the genomic DNA extraction effect of two methods namely high salt and low pH and modified CTAB was compared .

探讨漾濞泡核桃壳作木材胶粘剂原料的化学背景。
