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。

Hevea brasiliensis seeds belong to the typical recalcitrant seed, and have the typical recalcitrance: Desiccation sensitivity, chilly sensitivity and storage intolerance, therefore, Instant Sowing after Harvest has to be required in the practice, which restricts the development of some practices of Hevea brasiliensis seedling technique.

橡胶树种子属于典型的顽拗性种子,具有典型的顽拗特性:脱水敏感性、低温敏感性、不耐贮藏性,因此,在生产实践中不得不要求橡胶树种子"即采即播"。这限制了橡胶树育苗等相关生产的发展。

Firstly, because the triangle constrained matching propagation begins with the initial corresponding triangulations formed by a few seed points in the stereo pairs, this dissertation studies the affects of different numbers and different distributions of seed points on the image matching results through experimental analysis, and proposes a seed point selection strategy for different image texture conditions, an automatic selection algorithm is also designed that gives good distribution quality for a defined number of seed points.

首先,针对匹配传播过程中的种子点选取问题,通过实验分析研究了不同数量与分布的种子点所构成的初始三角网对匹配结果的影响,进而提出了不同影像条件下的种子点选取策略和一种自动提取一定数量、满足一定分布均匀度的种子点自动选取算法;其次,研究了海量数据情况下同名三角网的快速构建、数据组织存储与局部动态更新的方法;在此基础上,本文提出了随机传播、基于三角形拓扑关系的邻近传播和顾及纹理特征的自适应传播等三种传播策略,分别介绍了其详细的实现算法,并通过实验分析对这几种传播策略进行了比较,实验结果证明自适应传播方法在匹配的可靠性上最优。
