By GA3inducing female flower of the male sterile plants of Amorphophallus Konjac Koch, or by cutting off the male parts of the spadix, or bagging the inflorescenes, or by daubing a layer of vaseline on the stamen of the flower, the pollen pollution was successfully prevented and artificial hybrids were obtained. The stigmaexcision and 4% of sucrose can promote the seedssetting of the hybrid combination, whose pollination process can not be accomplished urder natural condition. Avoiding unnecessary moving of the mother plants, taking appropriate diseasepreventing measures, guarding against the going mouldy of the stigmas and inducing the rapid formation of the roots of mother plants can increase the viability of the crossbreeds.

采用GA3诱导花魔芋雌花可育的雄不育株、切去雄花序段、对花序套袋和在雄蕊上涂凡士林等办法,均可防止花粉污染而进行杂交授粉。切割柱头及涂4%蔗糖可使不能正常授粉的组合结籽。减少杂交母本植株搬动、加强防病措施、防止柱头霉变和促进母本植株生根等措施,可显著提高杂交后植株的成活率。
