摘　　要：对4种魔芋的开花习性和性状进行了系统观测研究,结果表明:花魔芋开花最早、花期短,滇魔芋与白魔芋次之,西盟魔芋开花最晚、花期最长.通过对魔芋花器的形态性状的比较分析,佛焰苞形状、肉穗花序比佛焰苞、附属器形状、有无中性器官、附属器散发的气味及成熟期果实颜色等几个形态性状种间的差异大;魔芋花器性状种内表现较为稳定,仅花序柄的颜色和斑纹以及附属器颜色有一定差异.The flowering habits and characters of four species of Amorphophallus were observed and analyzed systematically.The results showed that the earliest flowering species is A.konjac and its blooming duration is the shortest,which is followed by A.yunnanensis and A.albus.In addition,A.krausei has the latest flowering time and the longest flowering period.Based on comparison and analysis,marked interspecific differences were noticed in the morphological characters of konjac flower organ,including the shape of spathe,the shape of appendices,presence or absence of neutral organs,the odor produced by appendices and the color of ripening fruit.The intraspecific characters of konjac flower organ are relatively stable except for some differences in the mottling and the color of peduncle and appendix.
