Abstract

Abstract Objective This experiment was conducted to investigate the effects of foliar spray of polyamines on some morphological and physiological characteristics of rose. Materials and methods Experimental variants involved the type (putrescine, spermidine and spermine) and concentration (0 mM, 1 mM, 2 mM and 4 mM) of polyamines. In this research, the plant height, number of leaves and shoots, leaf area and thickness, fresh and dry weight of leaf and stem, the content of anthocyanin, soluble sugar, phenol and antioxidant capacity were measured 2 weeks after the end of experiment. Results Results indicated that among all polyamine types, putrescine has the highest effect on the morphological characteristics. Among different concentrations of polyamines, the concentration of 1 mM resulted in the highest increase in shoot fresh and dry weight. Putrescine application at 2 mM and 4 mM concentrations increased soluble sugar content. In the present study, polyamine treatment reduced the content of anthocyanin, phenol and antioxidant capacity. Conclusions It can be cocluded that application of polyamines improved some morphological and physiological traits in various ways.

叶面施用多胺改善了玫瑰的一些形态和生理特性

摘要目的研究叶面喷洒多胺对玫瑰某些形态和生理特性的影响。材料和方法实验变体涉及多胺的类型（腐胺、亚精胺和精胺）和浓度（0mM、1mM、2mM和4mM）。本研究在实验结束后2周测定了植株的株高、叶和梢数、叶面积和厚度、叶和茎的鲜干重、花青素含量、可溶性糖、苯酚含量和抗氧化能力。结果在所有多胺类型中，腐胺对其形态特征的影响最大。在不同浓度的多胺中，1mM的浓度导致芽鲜重和干重的最高增加。施用2mM和4mM浓度的Putrescine增加了可溶性糖含量。在本研究中，多胺处理降低了花青素、苯酚的含量和抗氧化能力。结论多胺的应用以多种方式改善了一些形态和生理性状。

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
