摘要:
对比了绣球Hydrangea macrophylla枝条水培扦插和基质扦插的生根时间、根生长状况,研究了5种不同浓度ABT5号生根粉、α-萘乙酸(NAA)和吲哚丁酸(IBA)处理对绣球扦插枝条水培生根的影响。结果表明,水培可以较基质扦插提早一周左右萌发新根,水培处理50 d绣球枝条生根率可达到93.33%以上,基质扦插培养的只有64.66%,水培处理显著高于基质扦插(P<0.05),且水培扦插生根数显著多于基质扦插生根数(P<0.05),根系生长状况较好。水培前利用100~200 mg?L-1的NAA,IBA和ABT5号处理均有促进绣球不定根伸长的作用,低浓度促进伸长作用不明显,而浓度过高则会抑制根的伸长。IBA促进绣球不定根生长的能力最强,且在50~250 mg?L-1浓度范围内,都有显著效果(P<0.05),NAA和ABT5在100 mg?L-1浓度以下没有显著的促进作用。综合分析本试验研究结果显示,NAA,IBA和ABT5号促进水培绣球生根的最佳浓度在150 mg?L-1左右。
Abstract:
In April of 2016, twigs of Hydrangea macrophyllawere cut from seedlings planted the previous year.The cuttings were treated by different concentrations of NAA, IBA and ABT5, and were cultured in nutrient solution and substrate to study rooting time and growth.The result showed that cuttings had rootings in water culture one week earlier than that in substrate.The rooting rate of water cultured cuttingsreached 93.33% in the 50 days, significantly higher than that in substrate, as well as root number and growth.The experiment resulted that treatment of IBA had the best effect on rooting of cuttings among 50-250mg?L-1,while that of NAA and ABT5 had no evident effect under 100mg?L-1.The results demonstrated that the best concentration of NAA, IBA and ABT5 was150mg?L-1 topromote rooting of H.macrophylla.
