摘要

背景与目的:随着新冠肺炎疫情席卷全球,人们在家的时间越来越多,许多家庭开始园艺,并购买各种观赏植物。许多品种的叙利亚木槿因其艳丽的花朵而被种植,或被用作景观灌木。叙利亚人通常以其高无性繁殖率而闻名。然而,众所周知,扦插繁殖的效果受内外因素的影响会有很大的差异。本试验旨在研究最佳生根床土壤组成和生长素对叙利亚红扦插生根的影响。方法:选用17个栽培品种的插条。采用园艺床土、沙土、混合土1和混合土2作为扦插繁殖的床土类型,分别施用500、1000和1500 mg·L-1浓度的IBA和NAA植物生长调节剂。结果:珍珠岩与蛭石组合生根率和生根数最高。另一方面,园艺床土的生根率极低。植物生长调节剂对大多数品种的根系生长均有促进作用。在IBA 500 mg⋅L-1处理下生根率最高,根数和根长在IBA 1500 mg⋅L-1处理下表现良好。结论:在许多品种中,生根率和根数随土壤的不同而不同。扦插最适宜的基质土为泥炭藓和蛭石混合土,添加生长调节剂可提高扦插效率,且IBA的效率优于NAA。然而,由于植物生长调节剂在某些品种中效果不佳,甚至存在问题,因此有必要确定每种品种的根系发育适合哪种详细的生长调节剂处理。

Effects of Bed Soils and Plant Growth Regulators on Root Growth of Hibiscus syriacus L.
Background and objective: As the COVID-19 pandemic gripped the entire world and people found themselves spending more time at home, many households began gardening, and purchased various ornamental plants. Many cultivars of Hibiscus syriacus are grown for their showy flowers, or used as landscape shrubs. H. syriacus is generally known for its high rate of asexual reproduction. However, it is known that the effectiveness of propagation by cuttings can have big differences depending on internal and external factors. This study was conducted to determine the effects of optimal rooting bed soil composition and auxin on the rooting of H. syriacus cuttings.Methods: Cuttings used in this study were from 17 cultivars. As types of bed soil for propagation by cutting, gardening bed soil, sand, mixed soil 1, and mixed soil 2 were used, and the plant growth regulators of IBA and NAA were applied at 500, 1000, and 1500 mg⋅L-1 concentrations.Results: The rooting rate and number of roots were highest with the combination of perlite and vermiculite. On the other hand, the gardening bed soil showed an extremely low rooting percentage. The root growth was improved in most cultivars when treated by plant growth regulator. The highest rooting rate was verified at IBA 500 mg⋅L-1 treatment while the number of roots and root length showed good result in IBA 1500 mg⋅L-1 treatment.Conclusion: In many cultivars, it was observed that the rooting rate and number of roots differed depending on the bed soil. The most suitable bed soil for the cuttings was a mixture of peat moss and vermiculite, and it was possible to increase the efficiency through treatment with a growth regulator, and the efficiency of IBA was better than that of NAA. However, it is necessary to identify which detailed growth regulator treatment is suitable for the root development of each cultivar, because plant growth regulator was less effective and even problematic in some cultivars.
