摘要
对5年生垂枝红千层实生后代的枝、叶片、花穗、花蕾等植物学性状的测量和观察结果表明:垂枝红千层实生后代产生了丰富的遗传变异,根据花穗长短、小花密度和着生状态,将实生后代分为长穗紧凑型、短穗紧凑型、长穗松散型、中长分散型、柳垂型、小花型等6个变异类型。
The five-year-old seedlings of the Callistetmon viminalis were used to analyze its botanical characteristics of the shoot, leaves and flowers. The result showed that： the individuals were significant difference, they could be divided into 6 types according to the flower spike length, flower density and growth status ： long-tight inflorescence, short-tight inflorescence, long-loose inflorescence, long-tight inflorescence, mid-length dispersed inflorescence, inflorescence hangs down like willow branch, floret inflorescence.
