将菊花父母本枝条插在水瓶里进行杂交育种,介绍了菊花枝条的剪取与水插、水培与授粉、后期管理与收种等操作技术,结出的菊花种子,出苗率达92.8％.水插菊花育种是个新尝试，操作方便，将室外授粉工作移到了室内进行;水插育种特适于家庭操作，便于早晚、中午随时观察和授粉;水插育种还可适当调整父母本的开花时间达到父母本开花一致;水插育种结的种子比地栽或盆栽菊花结的种子稍瘪一些，但基本不影响发芽，总之，水插菊花杂
腐植酸(Humic Acid,HA)是从有机废弃物材料中提取得到的天然有机肥料,对植物的生长发育有很好的促进作用,而这种促进效应的作用机理还不清楚.本研究的主要目的是探索腐植酸叶面肥(Foliar Humic Acid,FHA)对菊花光合特性和叶绿体超微结构的影响,进而探明腐植酸肥料促进菊花生长发育的作用机理.本试验以切花菊神马(Chrysanthemum morifolium cv.‘Jinba
