用不同浓度和组合配比的IAA、GA3、6-BA浸泡处理不同年生的花魔芋球茎,研究对花魔芋产生多叶的影响,结果表明:使用单一植物生长物质处理时,IAA诱导花魔芋根状茎、一年生及二年生多叶的最适浓度分别为10mg/L、5～7mg/L、1.5mg/L,多叶率最高可达67.85%;6-BA诱导不同芋龄花魔芋发生多叶的最适浓度均为30mg/L,多叶率分别达25.32%,52.34%,6.81%;而以60mg/L的GA3诱导不同芋龄花魔芋的最高多叶发生率为67%.单一植物生长物质处理材料以一年生魔芋效果最好.以40mg/L的GA3+30mg/L的6-BA和5mg/L的IAA+10mg/L的6-BA的组合为诱导花魔芋多叶发生最好组合,多叶率为57%左右.适当的植物生长物质处理能有效促进魔芋多叶的发生,增大光合作用面积,为魔芋提高产量奠定基础.
IAA and GA3,6-BA with different concentrations and combinations were used to treat bulbous flowers of Amorphophallus konjac to study the effects of different concentrations of IAA and GA3,6-BA on the production of multi-lobe. The results showed that when IAA and GA3,6- The optimal concentrations of annual, biennial and multi-leafy stems were 10mg / L, 5 ~ 7mg / L and 1.5mg / L, respectively. The highest leafy rate was 67.85% , The highest multi-leaf rate was 25.32%, 52.34% and 6.81% respectively, while the highest multi-leaf rate was 67% for GA3 with 60mg / L, The best materials for annual treatment of konjac were treated with 40 mg / L GA3 + 30 mg / L 6-BA and 5 mg / L IAA + 10 mg / L 6-BA as the best combination , Leafy rate of about 57% .Appropriate plant growth substances can effectively promote the occurrence of multi-leaf konjac and increase photosynthetic area, to lay the foundation for konjac yield increase.
