Abstract

Flooding is an important factor, decreasing Allium cepa bulb yield and quality. A comparison, in terms of biometrical and biochemical parameters, of five Allium cepa cultivars, grown at two different locations, characterized by contrasting conditions of water availability, i.e., precipitation excess at the end (A) or at the beginning (B) of plant growth, revealed a significant decrease in bulb weight, height, and diameter, and an increase in oxidative stress parameters, such as total antioxidant activity and polyphenol content, monosaccharides, proline, malonic dialdehyde in the condition of excessive soil humidity at the end of the vegetation period (A). Among the five cultivars studied (Zolotnichok, Zolotie cupola, Black prince, Globus, and Myachkovsky), the lowest variations of the above parameters under precipitation excess at cycle end or beginning were recorded in Zolotnichok and Zolotie cupola, which was in accordance with their high adaptability. Cultivar Myachkovsky showed the highest differences of the parameters examined between A and B conditions. Outer scale biochemical parameters demonstrated the highest stability in both regions. The participation of proline, monosaccharides, total polyphenols, and total antioxidant activity in plant defense against hypoxia, caused by waterlogging, was proved by high correlation coefficients between inner scale parameters (‘r’ from +0.714 to +0.920) and the latter with bulb yield (‘r’ from −0.745 to −0.924). High adaptability cultivars (Zolotie cupola, Zolotnichok, Black prince) showed significantly lower MDA inner/outer scales ratio and lipids outer/inner scales ratio compared to cultivars with moderate adaptability in (B) conditions. The results provide important information regarding biochemical peculiarities of Allium cepa in diverse soil humidity, which should be considered in future breeding activities of onion genotypes, characterized by high adaptability to different water excess conditions.
不同物候期降水过剩条件下葱品种产量、形态及生化指标的差异
水淹是影响葱球茎产量和品质的重要因素。对生长在不同水分条件下(即生长末期(A)和生长初期(B)降水过剩)的5个葱属品种进行了生物计量学和生化指标的比较,结果表明,不同水分条件下的葱属品种鳞茎质量、株高和株径显著降低,总抗氧化活性、多酚含量、单糖、脯氨酸、脯氨酸等氧化胁迫指标显著升高。在研究的5个品种(Zolotnichok、Zolotie冲天塔、Black prince、Globus和Myachkovsky)中,Zolotnichok和Zolotie冲天塔在循环结束或开始时降水过量条件下,上述参数的变化幅度最小,这与它们的高适应性相一致。栽培品种Myachkovsky在A和B条件下所测参数差异最大。外尺度生化参数在两个区域均表现出最高的稳定性。脯氨酸、单糖、总多酚和总抗氧化活性参与植物抗涝缺氧,其内部尺度参数(r = +0.714 ~ +0.920)与鳞茎产量(r = - 0.745 ~ - 0.924)呈高度相关。高适应性品种(Zolotie cupola、Zolotnichok、Black prince)在(B)条件下MDA内外鳞比和脂质内外鳞比显著低于中等适应性品种。研究结果为葱属植物在不同土壤湿度条件下的生化特性提供了重要信息,为今后对不同水分过剩条件具有高度适应性的洋葱基因型育种提供参考。
