据《Hortscience》2013年2月的一篇研究报道,来自尼亚卢布尔雅那大学农学系的研究人员研究了两次叶面喷施磷化钙(磷含量高,含少量钙和氮)对布雷奔苹果果皮色泽和花青素含量的影响。研究人员在果实成熟期对果皮中羟基桂皮酸、黄烷醇、酮类、黄酮醇和花青素的含量变化进行了记录,共计6次。每周记录色度值和明度系数。色度参数表明处理组和对照组果实红色着色度存在显著差异。喷洒磷化钙会引起大多数单糖、总糖、花青素和黄酮醇含量显著上升。处理组叶片中磷含量上升。
According to a February 2013 study by Hortscience, researchers from the Faculty of Agronomy, University of Nia Ljubljana, studied two foliar sprays of calcium phosphide (high phosphorus, with low levels of calcium and nitrogen) Effect of Breed Apple Peel Color and Anthocyanin Content. Researchers recorded changes in the content of hydroxycinnamic acid, flavanols, ketones, flavonols, and anthocyanins in the pericarp during fruit ripening for a total of 6 times. Chrominance values and brightness coefficients are recorded weekly. The chromaticity parameters indicate that there is a significant difference in the red shade of the fruits between the treatment group and the control group. Spraying calcium phosphide caused a significant increase in the content of most monosaccharides, total sugars, anthocyanins and flavonols. The content of phosphorus in leaves of treatment group increased.
