Abstract:
Strawberries are appreciated by consumers for their characteristic taste and health benefits, which enhance their demand throughout the year. Everbearing strawberries can produce fruits for a longer period and could thus meet this demand, but the fruit quality depends on environmental factors and the cultivar. This study focused on the effect of environmental conditions on the physical attributes and the composition of everbearing Capri cultivar fruit harvested from the end of June to the end of October. A positive correlation was observed between temperature and organic acid content (r = 0.87), and a positive correlation was observed between sunshine duration, anthocyanin (r = 0.87) and phenolic compound contents (r = 0.89). Additionally, the composition of sugars was affected by the environmental conditions. While strawberries harvested towards the end of October, when lower temperatures predominated, were larger in size and had a higher sugar/acid ratio, fruit harvested in the middle of August, when there were longer periods of sunshine, had higher anthocyanin and phenolic compound contents. In conclusion, strawberries with higher sugar/acid ratios are obtained when temperatures are lower, while strawberries exposed to longer periods of sunshine are richer in health-promoting compounds.
摘要:
草莓因其独特的味道和健康益处而受到消费者的赞赏,这增加了他们全年的需求。持久的草莓可以在更长的时间内生产水果,因此可以满足这种需求,但果实品质取决于环境因素和品种。这项研究的重点是环境条件对6月底至10月底收获的永久Capri品种果实的物理属性和组成的影响。温度与有机酸含量呈正相关(r=0.87),日照时间之间呈正相关,花青素(r=0.87)和酚类化合物含量(r=0.89)。此外,糖的组成受环境条件的影响。虽然草莓在10月底收获,当较低的温度占主导地位时,尺寸更大,糖/酸比更高,8月中旬收获的水果,当阳光充足的时候,花青素和酚类化合物含量较高。总之,当温度较低时,可以获得糖/酸比例较高的草莓,而暴露在较长时间阳光下的草莓富含促进健康的化合物。
