摘要: 以‘走马羊’ (叶柄紫色, 芽白色) 、‘江汉芋’ (叶柄绿色, 芽白色) 、‘红杆芋’ (叶柄乌绿
色, 芽淡红色) 为材料, 对3种类型多子芋生长动态进行了观察与比较。结果表明: (1) ‘江汉’熟性最早, ‘走马羊’其次, ‘红杆芋’最晚; (2) 熟性越晚, 叶片生长速度越快; (3) 分株出现的早晚是子芋形成早晚的标志, 分株数量反映了不同类型品种的分蘖特性, 与子芋数及子芋与孙芋的总数不呈正相关;(4) 球茎发育过程中, 各级球茎干物质积累存在库源关系。

Abstract: ‘Zoumayang taro’ (purple petiole, white bud) , ‘Jianghan taro’ ( green petiole, whitebud) and‘Red-petiole taro’ (purple-red petiole, pale red bud) were selected for observation and comparison of growing development among these three types of taro 〔Colocasia esculenta (L. ) Schott〕with multicormels. It indicated thatmaturity of‘Jianghan taro’was the ealiest, ‘Zoumaoyang taro’was the next earliest, and ‘Red-petiole taro’was the latest. The later the maturity was, the faster the leaf grew. Earliness or lateness of tiller appearing was an indicator of that of the first grade cormel formation. Numbers of tillers, which reflected the tillering charactor of different types of cultivars, had no positive correlation with numbers of the first grade cormels and total cormels. The source-sink relationship of drymatter accumulation exists among
corm, the first grade cormels and the second cormels.
