- 摘要:
- 以长度为10、15、20、25、30、35、40、45、50 cm富贵竹种苗为试材，研究了种苗下切口IBA处理和9种不同种苗长度对富贵竹的生根和幼苗黄化的影响。结果表明：IBA处理种苗根鲜重与清水对照相比差异显著；9种不同长度种苗间的根条数、根粗度、根总长、根鲜重、根干重、单株全黄化叶片数百分率、半黄化叶片数百分率、黄化叶<3 cm叶片数百分率均达到显著或极显著差异；种苗长度分别与根条数、根总长、根鲜重、根干重、单株全黄化叶片数百分率呈极显著的正相关关系。根据对种苗生根和幼苗黄化的指标及成本进行综合考虑，种苗下切口用10 mg/L IBA处理24 h，长度以30和35 cm的处理最好。
- Abstract:
- Taking 10，15，20，25，30，35，40，45，50 cm Dracaena sanderiana ‘Virens’ seedlings as materials，the effect of IBA treatment incision and 9 different lengths of seedlings on rooting and seedling etiolation were studied.The results showed that root fresh weight of seedling with IBA treatment reached significant differences compared to water;root number，root diameter，root length，root fresh weight，root dry weight，percentages of the whole leaves yellowing，half leaves yellowing and <3 cm yellowing leaves per plant of 9 different length of seedlings reached significant or very significant differences;Seedling length was highly significantly positively correlated to root number，root length，root fresh weight，root dry weight per plant，percentage of the whole leaves yellowing per plant，respectively.Taking into account the seedlings root number and seedling etiolation rates and cost，incision treated with 10 mg/L IBA for 24 hours and 30 and 35 cm length seedlings were the best.
