以6年生鸡嘴荔为试材,用不同浓度的乙烯利和多效唑进行处理,研究其对鸡嘴荔内源激素和花芽分化的影响,寻找解决鸡嘴荔成花率低和坐果率低的方法.结果表明,多效唑和乙烯利处理均能提高鸡嘴荔的成花率,其中,对鸡嘴荔成花率提高作用最明显的是处理A(乙烯利800 mg/L),末次梢成花率达到91.88%,比对照提高了18.59%;其次为处理D(多效唑600 mg/L),处理C(乙烯利400 mg/L)和处理B(多效唑1 000 mg/L),成花率分别为91.81%,80.44%和76.37%,分别比对照提高18.52%,7.15%和3.08%.在花芽分化前期,各处理能明显降低植株体内IAA和GA3的含量,提高ABA和ZT的含量,其中,处理A和处理D的效果优于处理B和处理C.在花芽形态分...

With 6-year Jizui litchi variety employed as the plant materials in the field experiment, the plants were treated with different consistence of PP333 and ethrel in the leaves before flower bud differentiation. To further the research of the effects of PP333 and ethrel on flower bud differentiation of Jizui litchi and the relationship between flower differentiation and the endogenous hormones, a better way is found out to control flower bud differentiation which solves the problem Of low flower bud differentiation ratio and low fruit-set ratio. ...
