背景:维生素C是一种拯救生命的分子。以维生素C为基础的育种需要小时,以便以新鲜食物的形式为人类提供增强免疫力的补充剂。
结果:使用品种研究了安纳托利亚地中海环境的多种相互作用(\'Calinda\',\'Rubygem\',\'Sabrina\',和“撒哈拉”)和果实成熟阶段。估计六个维生素C相关基因的遗传表达在开放场中显示出明显更高的表达。品种“Calinda”在有机酸中表现更好,但硬度较差。品种“Sabrina”显示出最高的果实硬度,但商业上所需的果实品质特征较低。品种\'撒哈拉\'表现最好的维生素C和水果发红,水果大小很高,体重,有机酸。色度趋势表明草莓果实中维生素C和花色苷同时积累。发现水果的过渡阶段对于代谢产物调节至关重要,并且对环境变化敏感。在“红”成熟期,“撒哈拉”品种的果实表达最高的维生素C水平(138.03mg/100gFW),而“Sabrina”品种的“转向”果实的维生素C含量最低(27.80mg/100gFW)。所有研究的维生素C相关基因表明品种“撒哈拉”的遗传表达最高,除了FaVTC2和FaMDHAR基因表现出最高的品种Rubygem遗传表达。\'
结论:品种之间的双向和三向相互作用,环境,在地中海气候下,成熟阶段对维生素C和果实品质调节具有重要意义。这表明研究实际领域中的综合影响是绝对必要的,而不是单一因素,控制,或实验室实验。相关分析表明,水果中维生素C含量是一个复杂的问题,主要取决于水果的颜色,尺寸,和坚定。主成分分析证实,“撒哈拉”品种是草莓维生素C育种的有希望的候选品种。
BACKGROUND: Vitamin C is a life saving molecule. Vitamin C based breeding is need of the hour in order to provide humans an immunity boosting supplement in the form of fresh food.
RESULTS: Multiple interactions of Anatolian Mediterranean environment were studied with cultivars (\'Calinda\', \'Rubygem\', \'Sabrina\', and \'Sahara\') and fruit maturity stages. Genetic expression of six vitamin C related genes was estimated showing significantly higher expression in open field. Cultivar \'Calinda\' performed better in organic acids but poor in firmness. Cultivar \'Sabrina\' showed highest fruit firmness but lower commercially desired fruit quality characters. Cultivar \'Sahara\' performed best for vitamin C and fruit redness, and was high in fruit size, weight, and organic acids. Chroma trends indicated simultaneous accumulation of vitamin C and anthocyanins in strawberry fruits. Transition stage of fruits was found most critical for metabolite regulation and sensitive to environmental changes. Fruits of cultivar \'Sahara\' at \'Red\' maturity stage expressed highest vitamin C levels (138.03 mg/100 g FW) whereas \'Turning\' fruits of cultivar \'Sabrina\' had lowest vitamin C content (27.80 mg/100 g FW). All studied vitamin C related genes indicate highest genetic expression for cultivar \'Sahara\', except for genes FaVTC2 and FaMDHAR which exhibit highest genetic expression for cultivar \'Rubygem.\'
CONCLUSIONS: Two-way and three-way interactions between cultivars, environments, and maturity stages were significant for vitamin C and fruit quality regulation under Mediterranean climate. This indicates an absolute requisite of studying combined influences in actual field, rather than single factor, controlled, or lab experiments. Correlation analysis showed that vitamin C content in a fruit is a complex subject and mainly depends on fruit color, size, and firmness. Principal Component Analysis validated that cultivar \'Sahara\' is a promising candidate for vitamin C based breeding in strawberry.
