- 摘要:
- 采用单因素随机区组试验设计，研究了不同浓度多效唑和乙稀利对“台农一号”芒果抽生花序的影响。结果表明：“台农一号”芒果摘除早花后，叶面喷施1次300、450、600 mg/L的多效唑与200、250、300 mg/L的乙稀利，均有提高二次花抽花率的作用；多效唑浓度在300～600 mg/L范围内，催花效果与浓度呈正相关；乙稀利浓度250 mg/L的抽花率比200 mg/L的高，300 mg/L时流胶现象比较严重，抽花率反而比250 mg/L时低。多效唑与乙稀利各处理对花序长度均有不同程度的降低。
- Abstract:
- The single-factor randomized block experiment was adopted and found out that different density of paclobutrazol and ethephon had different influence on the flowering rate of ‘Tainung No.1’ Mango.The results showed that 300，450，600 mg/L paclobutrazol and 200，250，300 mg/L ethephon，all of them would improve secondary flowing rate.Paclobutrazol in a certain range of concentration（300～600 mg/L）increased with the dose to enhance efficacy.250 mg/L ethephon had a higher rate than 200 mg/L ethephon.However，300 mg/L ethephon had a lower rate than 250 mg/L ethephon because of a serious gum.What’s more，the length of florescence had decreased in varying degrees after treated with paclobutrazol and ethephon.
