Other claims from this paper (12)
- Observation The mosses showed significant plasticity in chlorophyll and carotenoid content and Chl a/b ratio.
- Association Carboxylase activity of Rubisco is an indicator of the photosynthesis intensity of mosses.
- Association Carboxylase activity of Rubisco differs between endohydric and ectohydric moss species.
- Association Under unfavorable environmental conditions, carotenoid content increased in moss shoots.
- Association Under unfavorable environmental conditions, the proportion of chlorophyll a in the total chlorophyll pool decreased to 52–56 %.
- Association Under unfavorable environmental conditions, the proportion of chlorophyll b increased.
- Association Under moisture deficiency, antioxidant activity increased by 27–30 % in moss shoots.
- Association Atrichum undulatum had 25–53 % higher and more stable Rubisco activity than Ceratodon purpureus, supporting a higher photosynthesis intensity.
- Association Polytrichum formosum had 25–53 % higher and more stable Rubisco activity than Ceratodon purpureus, supporting a higher photosynthesis intensity.
- Association Atrichum undulatum gametophores had a 3.5–4.0 times higher antiradical activity.
- Observation Flavonols and anthocyanins were present in extracts of P. formosum.
- Observation Flavonols and anthocyanins were present in extracts of C. purpureus.
