Biostimulants and other plant growth promoters can provide an effective solution to the challenge of urbanisation and climate change. 'Roseum' is a globally popular deciduous shrub species that can be made more resistant to urban influences by using natural growth-promoting substances. In our study, we investigated the effects of growth promoters Kelpak, Bistep and Yeald Plus on the species, both histologically and physiologically (proline stress hormone measurement). Our measurements were complemented using the analysis of rhizosphere alkaline phosphatase, β-glucosidase and β-glucosaminidase enzymes, to obtain a more complete picture of the combined effect of biostimulants and species. We found that the Bistep biostimulant had an outstanding effect on the leaf tissue culture results of the variety. The transpiration and evapotranspiration findings also confirmed the efficacy of biostimulants. In the case of POD activity and rhizosphere enzyme measurements, Bistep and Yeald Plus obtained statistically higher values than the control group. Kelpak produced better results than the control group in several measurements (alkaline phosphatase levels; evapotranspiration results), but in other cases it resulted in lower values than the control treatment. The use of Bistep and Yeald Plus can greatly assist growers in the cultivation of 'Roseum' in an urban environment.
生物刺激剂和其他植物生长促进剂可以为应对城市化和气候变化挑战提供有效的解决方案。“玫瑰红”是一种全球流行的落叶灌木物种，通过使用天然生长促进物质可以使其更能抵抗城市环境的影响。在我们的研究中，我们从组织学和生理学方面（脯氨酸应激激素测量）研究了生长促进剂凯尔帕克（Kelpak）、比斯泰普（Bistep）和叶尔德加（Yeald Plus）对该物种的影响。我们还通过分析根际碱性磷酸酶、β-葡萄糖苷酶和β-氨基葡萄糖苷酶来补充测量结果，以更全面地了解生物刺激剂和该物种的综合作用。我们发现，比斯泰普生物刺激剂对该品种的叶片组织培养结果有显著影响。蒸腾和蒸散的结果也证实了生物刺激剂的功效。在过氧化物酶（POD）活性和根际酶测量方面，比斯泰普和叶尔德加在统计学上比对照组获得了更高的值。凯尔帕克在几项测量中（碱性磷酸酶水平；蒸散结果）比对照组产生了更好的结果，但在其他情况下，其值低于对照处理。使用比斯泰普和叶尔德加可以极大地帮助种植者在城市环境中种植“玫瑰红”。
