Biochemical composition of Apium graveolens var. Rapaceum (Mill.) Gaud

Celeriac (Apium graveolens L., Apiaceae), originating from the Mediterranean basin, is a two-year-old species grown worldwide. The article presents the content of chlorophylls a and b, β-carotene and anthocyanin in various celery root varieties, and an assessment of their resistance to septoriosis and the yield of root crops. The studies were carried out on the basis of the All-Russian Scientific Research Institute of Vegetable Growing, a branch of the Federal Scientific Vegetable Center (Moscow Region, Ramensky District) in 2014-2016. The total content of anthocyanins in the leaves in varieties with anthocyanin coloring on the leaf stem is on average 1.32 mg /100 g, in the varieties with a green stem, 0.90 mg /100 g, β-carotene -1.82 and 1.67 mg /100 g, chlorophyll a - 86.5 and 81.4 mg/100 g, chlorophyll b - 43.1 and44.9 mg/100 g wet weight, respectively. Linear correlation analysis allowed to establish a reliable (at 5% significance level) positive relationship between the yield of root crops and the total content of anthocyanins in celery leaves (r = 0...
