摘要

在 PEG-6000 模拟干旱胁迫条件下，比较研究了外源施用多胺（PA）对抗旱大麦栽培品种（Hordeum vulgare cv. Bülbül-89）和易旱大麦栽培品种（Hordeum vulgare cv. Burakbey）的一些生理特征和脯氨酸含量的影响。结果发现，与对照组相比，施加干旱胁迫对所有生理参数都有至少 40% 的不利影响。干旱胁迫还显著增加了栽培品种的脯氨酸含量。然而，在干旱胁迫条件下施用外源 PA（尤其是两种大麦栽培品种上的 Spm）对研究的所有生理参数都有积极影响。在所有 PA（尤其是 Spd）存在的情况下，易受干旱影响的 Burakbey 栽培品种的脯氨酸含量都有所增加。而在 Bülbül-89 中，增加脯氨酸含量的多胺只有 Spd。在多胺中，Cad 是对所有参数影响最小的多胺。孟加拉国植物学杂志52(3):805-812，2023 年（9 月）

Impacts of polyamines on the morpho-physiological characters and proline content of the two different barley cultivars

Impacts of the exogenously applied polyamines (PAs) on some physiological features and proline content in drought-resistant barley cultivars (Hordeum vulgare cv. Bülbül-89) and drought-susceptible (Hordeum vulgare cv. Burakbey) were comparatively examined under PEG-6000-simulated drought stress conditions. It was found that drought stress application had adverse impact on all physiological parameters at least 40% compared to that of the control group. It also dramatically increase the proline content of the cultivars. However, exogenously applied PAs (especially Spm on both barley cultivars) under drought stress conditions showed positive effect on all physiological parameters studied. The proline content increased in the presence of all PAs (especially Spd) in drought-susceptible Burakbey cultivar. If in Bülbül-89, polyamine that increases the proline content was Spd only. Among polyamines Cad was found as the polyamine that provided generally the least successful on all parameters. Bangladesh J. Bot. 52(3): 805-812, 2023 (September)

期刊介绍： Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments. Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December. Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
