Effects of Different Plant Growth Regulators on the Growth of Hybrid Cymbidium
摘要
Abstract
[Objective] To study the effects of different plant growth regulators on the growth of hybrid Cymbidium.[Method] The effects of different plant growth regulators and their concentrations on the growth of hybrid Cymbidium were studied by using two-year hybrid Cymbidium Red Beauty as material under foliar spraying and pseudobulb spraying.[Result] Compared with the control,100 mg/L GA3 and 150 mg/L GA3 + 150 mg/L 6-BA under foliar spraying promoted the flower bud differentiation at the early stage,but the flower buds failed to form at the later stage,while the other combinations and flower buds differentiation were inhibited.High concentrations of TDZ and 6-BA were not conducive to flower bud differentiation,especially 6-BA.However,when 6-BA was used in combination with GA3 at a suitable concentration,the inhibition of floral bud differentiation was weakened.Meanwhile,plant growth regulators could enhance the induction of axillary buds,the effect of GA3 on the length of pedicel can be effectively improved by the influence of pedicel length.When GA3 was combined with 6-BA,although the length of pedicel was increased,the number of flowering buds was serious at the later stage.In the case of pseudobulb spraying,low concentrations of 6-BA and 6-BA combined with low concentrations of GA3 promoted flower buds and axillary bud formation.[Conclusion]In the flower bud differentiation of two year old hybrid Cymbidium,it is better that pseudobulb should be sprayed with low concentrations of 6-BA;to promote the length of pedicel,it is appropriate to spray the leaf surface with low concentrations of GA3.关键词
