以MS为基本培养基、一品红花序轴为外植体,通过不同植物生长调节剂,诱导不同品种愈伤组织的发生.结果表明一品红不同品种对培养基中不同植物生长调节剂的浓度及其组合的反应不一,同一品种在不同浓度的植物生长调节剂的培养基上以及不同品种在相同浓度植物生长调节剂的培养基上培养时,愈伤组织的诱导率差异较大,从而筛选出适合一品红不同品种花序轴愈伤组织诱导的配方. 相似文献

In this paper we propose a method to model flowers of solid shape. Based on （Ijiri et aL, 2005）＇s method, we separate individual flower modeling and inflorescence modeling procedures into structure and geometry modeling. We incorporate interactive editing gestures to allow the user to edit structure parameters freely onto structure diagram. Furthermore, we use free-hand sketching techniques to allow users to create and edit 3D geometrical elements freely and easily. The final step is to automatically merge all independent 3D geometrical elements into a single waterproof mesh. Our experiments show that this solid modeling approach is promising. Using our approach, novice users can create vivid flower models easily and freely. The generated flower model is waterproof. It can have applications in visualization, animation, gaming, and toys and decorations if printed out on 3D rapid prototyping devices. 相似文献
