- 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 b increased.
- Association Under moisture deficiency, antioxidant activity increased by 27–30 % in moss shoots.
