High temperature is a limiting factor for the production and quality of tomato fruit, especially during the summer in tropical regions, when the cultivation must be carried out in a protected environment due to heavy rainfall. Thus, there is a need to identify cultivars adapted to these climatic conditions. In this study we aimed to carry out the selection of thermotolerant cultivars, adapted to protected cultivation, to combine characteristics of high yield, fruit quality, and consumer acceptance through principal component analysis (PCA). ‘Fascínio’, ‘Lampião’, ‘Vedette’, ‘Tytanium’, ‘Candieiro’, ‘Mariana’, and ‘Shanty’, grown under high temperatures (36 °C), differed in yield, physicochemical parameters of fruit (soluble solids, titratable acidity and ripening index), bioactive compounds (ascorbic acid, lycopene, and β-carotene), and sensory analysis. According to the PCA, ‘Fascínio’ stood out due to its high yield characteristics (68.32 t ha−1), with a higher prevalence of large (38.6%) and medium (54.9%) fruit, sweeter fruit (4.33 °brix), and were preferred by the consumer, in addition to having thermotolerance and adaptation for the greenhouse. ‘Candieiro’ presented with the highest content of bioactive compounds (ascorbic acid: 45.31 mg/100 g and lycopene: 2.73 mg/100 g), attributes that add value to the fruit and may fulfill the needs of more demanding consumers.

选择具有高产量和营养品质的耐热意大利番茄品种,以满足消费者在保护栽培下种植的口味

高温是番茄果实产量和质量的限制因素,尤其是在热带地区的夏季,由于降雨量大,必须在受保护的环境中进行种植。因此,需要确定适应这些气候条件的栽培品种。在本研究中,我们旨在通过主成分分析 (PCA) 来选择适合保护栽培的耐热品种,以结合高产、果实质量和消费者接受度的特点。'Fascínio'、'Lampião'、'Vedette'、'Tytanium'、'Candieiro'、'Mariana' 和 'Shanty',在高温 (36 °C) 下生长,在产量、水果理化参数(可溶性固体、可滴定酸度和成熟指数)、生物活性化合物(抗坏血酸、番茄红素和β-胡萝卜素),和感官分析。根据 PCA 的说法,“Fascínio”因其高产量特性而脱颖而出(68.32 吨公顷-1 ),大 (38.6%) 和中等 (54.9%) 水果、更甜的水果 (4.33°白利糖度) 的流行率更高,除了具有耐热性和对温室的适应性外,还受到消费者的青睐。'Candieiro' 具有最高含量的生物活性化合物(抗坏血酸:45.31 毫克/100 克和番茄红素:2.73 毫克/100 克),这些属性可以增加水果的价值,并可以满足更苛刻的消费者的需求。
