摘　　要：魔芋在产业发展中，长期无性繁殖导致种性退化和品质下降。利用魔芋杂交有性繁殖，是保持种性、品种定向培育和丰富遗传资源的有效途径。魔芋有性繁殖周期为4～5年，为提高杂交结实率，获得需要的杂交种子量，研究杂交种子繁育技术尤其必要。文章通过人工授粉试验，初步研究了不同授粉时期对花魔芋杂交结实率的影响。试验结果表明，魔芋开花第2天和上午9：00—10：00时是人工杂交授粉的最佳时期，有明显的杂交结实效果。In industrial development, the seeds of Amorphophallus. konjac were reproduced with long-term asexual, therefore the A. konjac quality degenerate and decline. The use of A. konjac hybrid sexual reproduction was the effective way to maintain species, varieties of directional cultivation and rich genetic resources. The cycle of A. konjac sexual reproduction was 4 -5 years. In order to improve the hybrid seed production and acquire the hybrid seeds, the hybrid seeds breeding technology was particularly necessary. Based on the artificial pollination experiments, the effects of different pollination period on hybridization Percentage of seed-setting of A. konjac was preliminary studied. The results showed that the best period of artificial hybridization pollination was the next day of blossom and from 9：00 to 10：00 on morning. The A. konjac hybrid seed setting rate could be obviously improved.
