Senticosus, an important shrub under the Korean Pine broad-leavd forest and its secondary forest in heterogeneous habitats and the dynamics of its seed pool have been studied by observations in location. The results showed that transformation rates from seeds to seedlings were in the following order : 16.8% in Larch plantations, 4. 1% in Mongolian oak forests, 2.7% in Birch forests, 1.8% in Korean Pine plantations, and 0.5% in hard wood forests.The life-span of seeds was determined to be four years in the simulating seed pool under Larch plantations. The percentage of the seedling output was, 14.5% in the 2nd year, 10. 1% in the 3rd year, and 1 .8% in the 4th year. Other types of the seed output were those f decayed 33. 1 %, senescent, 22.3%,predated by mice 14. 1%, which was variable due to the variation in the number of mouse, and only 1. 17% were eaten by insects and other soil animals.展开更多
单核苷酸多态性(SNP)标记具有二态性等优点,可用于种子纯度鉴定。应用焦磷酸测序技术对黄瓜SNP位点CLA13(C/G)进行了分析。结果表明,该位点在16个黄瓜杂交种中多态信息量达0.556,处于高度多态,适于其中7个品种的纯度检测;为提高种子纯...单核苷酸多态性(SNP)标记具有二态性等优点,可用于种子纯度鉴定。应用焦磷酸测序技术对黄瓜SNP位点CLA13(C/G)进行了分析。结果表明,该位点在16个黄瓜杂交种中多态信息量达0.556,处于高度多态,适于其中7个品种的纯度检测;为提高种子纯度鉴定效率,引入DNA Pooling技术,建立高效率的3Pooling SNP Pyrosequencing检测分析模型,并验证了分析模型的可行性。展开更多
