1上西早生甜柿离体快繁技术研究显示文摘对上西早生甜柿的离体快繁技术进行了研究 ,比较了基本培养基、激素种类和浓度对组培苗生长状态和快繁指数的影响。结果显示MS培养基优于MS(1/ 2N) ,ZT 1 0mg/L的快繁效果明显好于BA 5 0mg/L。生长在ZT 0 5mg/L、BA 1 0mg/L中的组培苗高度及生长状态 ,与ZT 1 0mg/L相比无显著差异 ,IAA的快繁效果好于IBA和NAA。刘晓娜 马俊莲 张子德 宋春丽 2004河北农业大学学报2004,27,1:8
2Color Image Segmentation by Edge Linking and Region Grouping显示文摘A novel method toward color image segmentation is proposed based on edge linking and region grouping. Firstly,the edges extracted by the Canny detector are linked to form regions.Each of the end points of edges is connected by a direct line to the nearest pixel on another edge segment within a sub-window.A new distance is defined based on the feature that the edge tends to preserve its original direction.By sampling the lines to the image,the image is over-segmented to labeled regions.Secondly,the labeled regions are grouped both locally and globally.A decision tree is constructed to decide the importance of properties that affect the merging procedure.Finally,the result is refined by user’s selection of regions that compose the desired object. Experiments show that the method can effectively segment the object and is much faster than the state-of-the-art color image segmentation methods.王宁 杨杰 2011Journal of Shanghai Jiaotong university(Science)2011,16,4:0
