Abstract
The content of pigment plastids was studied in 98 species of vascular plants on the island of Western Spitsbergen (78° 02'N, 14° 12'E). It has been established that species of the Arctic fraction (85%) with a circumpolar areal prevail. The range of chlorophyll content in this group is 0.4–2.6 mg/g wet weight, carotenoids – 0.09-0.86; the ratio of chlorophylls is 1.7–4.3, the ratio of chlorophylls to carotenoids is 1.5–5.4, the size of LHC-II is 42–82%. The range of the content of the sum of flavonoids in 54 species of vascular plants of the Arctic fraction was from 0.9 to 10.9% of abs. dry weights. It is found that 70% of species have a positive relationship between the content of chlorophylls and flavonoids.
