摘　　要：珠芽魔芋是东南亚地区的特色野生魔芋种,适宜在高温高湿环境生长。以珠芽魔芋人工诱导开花进行规模化无性育种,可将魔芋繁殖系数从1位数提高到约330倍。采用催苗技术让种子及叶面球茎提早出苗,可显著延长魔芋生长周期,使魔芋种植周期由3年缩短为1年,实现当年种植收获商品芋,从而避免魔芋种植过程中种植材料反复休眠的固有特性,可使魔芋从低产作物提升为优质高产作物,显著降低种植风险,使魔芋总量大幅增长,市场推广前景十分广阔。Amorphophallus konjac powder was deemed as a kind of international agricultural trade. Low corm multiplication rates and inefficient rates of propagation resulted in a long growth cycle for konjac. It took at least three years to obtain a commercial corm for processing from a propagation corm or a tissue cultured seedling. Moreover, severe disease levels also contributed to the low output. It had from single - digit times to about 330 times by inducting flower breeding and seed without pollination. The procedure developed for staggered multiple seedling release of A. muelleri was a desirable solution for overcoming the above barriers and shortening the growth cycle from 3 - 4 years to 9 - 10 months.This meant that the corm could be harvested the same year as it was planted. The entrenched idea of a long lead time for production of cultivated konjac could be completely overturned, resulting in a significant increase in overall production of this high yield crop.
