摘要

目的:探讨大蒜在自然条件和实验条件下积累锗的能力。方法:大蒜鳞茎中锗的积累效率取决于植株处理方法。非根(叶)敷料比根敷料有效5倍;使大蒜鳞茎组织内锗浓度提高到20.0 μg/kg。采用添加二甲亚砜的日耳麦醇溶液进行无根处理效果更好,有利于锗渗透到植株组织中。结果与讨论:沃罗涅日、莫斯科州、特沃州低地条件下栽培的24个冬季大蒜品种(19个样品)和春季大蒜品种(5个样品)的鳞茎中锗含量较低,山东、卡拉恰伊-切尔克斯和阿尔泰山山区条件下栽培的鳞茎中锗含量较低。23份球茎中锗含量不超过4.2 μg/kg;在Karachay-Cherkessia条件下生长的样品中,该元素的含量为5.0 μg/kg。结论:含锗物质在大蒜鳞茎中积累锗的效率与施用方法有关。结果表明,大蒜的根和叶积累锗最活跃;这些器官中锗的含量分别是对照组的115.2倍和141.0倍。大蒜中该元素的浓度为78 μg/kg,是对照的37.1倍。

Ability of Garlic (Allium Sativum L.) to Accumulate Germanium under Natural and Experimental Conditions

Objective: The ability of garlic to accumulate germanium under natural and experimental conditions was discussed. Methods: The efficiency of accumulation of germanium in the garlic bulbs was dependent on the plant dressing method. Non-root (foliar) dressing proved to be 5 times more effective than root dressing; it afforded an increase in the germanium concentration within the garlic bulb tissues to 20.0 μg/kg. More effective was non-root dressing using Germatranol solution added with dimethyl sulfoxide, facilitating penetration of germanium into the plant tissues. Results and Discussion: The content of germanium in the bulbs of 24 samples of winter garlic varieties (19 samples) and spring garlic varieties (5 samples), grown in the lowland conditions of the Voronezh, Moscow, and Tver oblasts, as well as in the mountain conditions of the Shandong province (PRC), Karachay-Cherkessia, and Altai Mountains, was found to be at a low level. The germanium content in the bulbs did not exceed 4.2 μg/kg in 23 samples; in the sample grown in the conditions of Karachay-Cherkessia the content of this element was 5.0 μg/kg. Conclusions: It was shown that the efficiency of germanium accumulation in the garlic bulbs depends on the method of application of the germanium-containing substance. It was found that garlic roots and leaves accumulated germanium most actively; the respective germanium concentrations in these organs were 115.2 and 141.0 times higher than in the control. In the garlic cloves, the concentration of this element exceeded that in the control by 37.1 times, being 78 μg/kg.

期刊介绍: Russian Journal of Bioorganic Chemistry publishes reviews and original experimental and theoretical studies on the structure, function, structure–activity relationships, and synthesis of biopolymers, such as proteins, nucleic acids, polysaccharides, mixed biopolymers, and their complexes, and low-molecular-weight biologically active compounds (peptides, sugars, lipids, antibiotics, etc.). The journal also covers selected aspects of neuro- and immunochemistry, biotechnology, and ecology.
