Correlation between Variegation of im Seedlings and Excitation Pressure Experienced under Various Growth Conditions.
Variegation was measured as the percentage of white sector area as described in Methods. All plants were germinated and grown for 1 week at 5 μmol photons m−2 s−1 at 25°C under 8/16-h day/night cycle and were then shifted to different temperature/irradiance conditions for the remainder of the experiment. Temperature/irradiance: closed circles, 25/150; closed triangles 25/450; open squares, 12/50; open circles, 12/150; open triangles, 12/450; closed squares, 25/50 CL; closed circles, 25/150 CL; closed triangles, 25/450 CL. Data represent the mean ± se with five to six different plants per treatment.
