摘要

背景:花椰菜头被认为是蛋白质、不饱和脂肪酸、多种矿物质元素、维生素和高含量生物活性物质的丰富来源。一些研究报道,生物活性物质在花椰菜中的积累动态可能受到多种因素的影响。目的:研究花椰菜头中抗坏血酸、B族维生素、常量营养素等生物活性成分含量与花椰菜头成熟期和生育期的关系。方法:以“Rocky F1”和“Unibotra F1”为研究材料,研究了花椰菜中熟杂交品种在花头成熟期和栽培期不同阶段维生素C、B族维生素(硫胺素、吡醇、泛酸、烟酸、肌醇)和7种常量营养素(硅、铝、钙、镁、钠、磷、钾)含量的变化。用滴定法测定了花椰菜头中抗坏血酸的含量。采用分光光度法对水溶性B族维生素进行定量分析。采用化学光谱法测定其常量营养素的含量。结果:在春季栽培条件下,Rocky F1花椰菜的穗部技术成熟阶段,Unibotra F1花椰菜的穗部技术成熟阶段,在夏季栽培条件下,Unibotra F1花椰菜的穗部形成阶段,抗坏血酸含量最高。除了泛酸外,两种杂交品种新形成的头中B族维生素的含量都很高。在春耕条件下,Rocky F1杂交种颖穗技术成熟阶段、Unibotra F1杂交种颖穗形成阶段(Si、Al、Na、P)和颖穗成熟中期(Ca、Mg)的宏量营养元素含量较高。在夏季栽培条件下,Rocky F1杂交种新穗形成阶段的大部分常量营养元素含量较高,Unibotra F1杂交种新穗形成阶段的Si、Al、P含量较高,成熟中期的Ca、Mg、K -含量较高。结论:花椰菜头中抗坏血酸、B族维生素、常量营养素等生物活性成分的含量受花椰菜成熟期和栽培期(春、夏)的影响。在亚美尼亚共和国半沙漠地区制定目标饮食和种植花椰菜时,应考虑到这一点。关键词:抗坏血酸,B族维生素,常量营养素,花椰菜头熟期

Dynamics of bioactive substances accumulation during cauliflower maturation as a way to ensure functional crop properties
Background: Cauliflower heads are recognized as a rich sources of proteins, unsaturated fatty acids, numerous mineral elements, vitamins, and a high content of bioactive substances. Some studies report that the dynamics of accumulation of bioactive substances in cauliflower can be influenced by various factors. Objective: To determine the dependence of the content of bioactive components (ascorbic acid, B vitamins, macronutrients) on the stage of maturity of cauliflower heads and on the growing period.Methods: The study investigated the variation in vitamin C, B group vitamins (thiamine, pyridoxine, pantothenic acid, nicotinic acid, inositol), and seven macronutrients (silicon, aluminum, calcium, magnesium, sodium, phosphorus, potassium) during different stages of head ripening and cultivation periods in medium-ripening hybrids of cauliflower, specifically ‘Rocky F1’ and ‘Unibotra F1’. Ascorbic acid content in cauliflower heads was determined by the titration method. Quantitative analysis of the water-soluble B group vitamins was performed spectrophotometrically. The content of macronutrients was determined by the chemical-spectral method.Results: The maximum content of ascorbic acid in cauliflower Rocky F1 hybrid was observed at the stage of the heads technical ripening in spring cultivation conditions, and in Unibotra F1 hybrid - in the phase of new head formation in summer growing conditions. The content of group B vitamins, with the exception of pantothenic acid, was high in newly formed heads in both studied hybrids. In the conditions of spring cultivation, most of the studied macronutrients were high for Rocky F1 hybrid in the stage of technical ripening of heads, and for Unibotra F1 hybrid in the phase of new head formation (Si, Al, Na, P) and in middle ripening stage (Ca, Mg). Under the conditions of summer cultivation, most of the macronutrients were high for Rocky F1 hybrid in the phase of new head formation, and in Unibotra F1 hybrid - Si, Al, P were high in the phase of new head formation, and Ca, Mg, K - in middle ripening stage. Conclusion: The content of bioactive components (ascorbic acid, B vitamins, macronutrients) in cauliflower heads is influenced by the stage of cauliflower maturity and the cultivation period (spring, summer). This should be taken into account when developing targeting diets and growing cauliflower in semi-desert zones of the Republic of Armenia.Keywords: ascorbic acid, B vitamins, macronutrients, cauliflower head ripening stage
