When Kalanchoe Blossfeldiana is exposed to repeated short-days there is a marked increase in both the amount and the rate of the fixation of carbon dioxide in the dark (3). Plants which have received a series of short day and long night cycles show an uptake of CO2 in each dark period which begins slowly, increases to a maximum and falls again; finally it… CONTINUE READING
