Fig. 3From: Morphological and physiological adaptation characteristics of lithophytic bryophytes to karst high calcium environmentGrowth of Didymodon constrictus in different calcium environments. A the growth state of Didymodon constrictus before treatment with Ca2+ solution, (B) the growth state of Didymodon constrictu after 2 months of culture with Ca2+ solution. ①:Ca2+concentration is 0 mmol/L, ②:Ca2+ concentration is 50 mmol/L, ③:Ca2+ concentration is 100 mmol/L, ④:Ca2+concentration is 200 mmol/L, ⑤:Ca2+ concentration is 400 mmol/L, ⑥: Ca2+concentration is 800 mmol/LBack to article page
