摘要

研究的目的是以生产中广泛使用的亚洲品种为例,确定人工紫外线照明对草莓果实中生物活性物质含量的影响。该研究于 2019-2021 年在利佩茨克地区进行。在草莓生长季节的条件下,对已经生根的成年灌木丛进行了土块移植。在人工照明条件下,土壤的水气状况与露地相似。在人工光照条件下,亚洲品种的园草莓植株比阳光下晚 10 天开花,果实重量较小,有机酸和干可溶性物质含量较低。无论光照性质如何,植株积累的水溶性果胶物质数量相同。草莓果实中维生素 P 组黄色着色物质--黄酮醇和同组粘合剂--儿茶素的含量与光照性质无关。紫外线下的草莓植株积累的抗坏血酸量与阳光下的相同。与人工紫外线下的阳光相比,草莓果实中的类胡萝卜素和β-胡萝卜素等色素含量最少。与人工紫外线相比,阳光下草莓果胶物质、花青素、单宁和着色物质(包括单宁)的含量明显更高。无论光照性质如何,草莓植株的含水量和果实的 pH 值相同,抗坏血酸、黄酮醇、儿茶素和水溶性果胶物质的积累量也相同。

Comparative biochemical composition of garden strawberry fruits of the Asia variety under natural and artificial lighting
The purpose of the study is to establish the effect of artificial ultraviolet lighting on the content of biolo-gically active substances in strawberry fruits using the example of the Asia variety, which is widely used in production. The study was conducted in 2019–2021 in the Lipetsk Region. Transplantation of strawberries under conditions of a growing season was carried out by already rooted adult bushes with a clod of earth. The water-air regime of the soil under artificial lighting conditions was similar to open ground. Under artificial lighting, garden strawberry plants of the Asia variety bloomed 10 days later, had a smaller fruit weight, and had a lower content of organic acids and dry soluble substances than under the sun. Plants accumulated the same amount of water-soluble pectin substances regardless of the nature of the lighting. The content of yellow coloring substances from the vitamin P group – flavonols, as well as binders from the same group – catechins in strawberry fruits did not depend on the nature of the lighting. Strawberry plants under ultraviolet light accumulated the same amount of ascorbic acid as under sunlight. Compared to sunlight under artificial ultraviolet, strawberry fruits contained the least amount of pigments, including carotenoids and β-carotene. A significantly higher level of pectin substances, anthocyanins, tannins and coloring substances, including tannin, in strawberries under sunlight was established in comparison with artificial ultraviolet. Regardless of the nature of lighting, strawberry plants had the same water content and pH of the fruits and accumulated the same amount of ascorbic acid, flavonols, catechins and water-soluble pectin substances.
