Abstract
In 5-d-old etiolated seedlings of Sorghum bicolor, 12 h of darkness after 5 min in red light eliminated a lag before the accumulation of chlorophylls in subsequent continuous white light. Increasing the dark period to 24 h and 36 h, increased the rate of chlorophyll accumulation in the later stages of greening. Exogenous δ-aminolevulinic acid neither completely removed the lag, nor increased the rate of chlorophyll accumulation. Cycloheximide (25 μg ml−1) and 6-methyl purine (5.0 μg ml−1), given continuously or only until the 12 h dark period following the red light irradiation, restored the lag and decreased the rate of chlorophyll accumulation. D-threo-chloramphenicol (400μg ml−1) also decreased the rate of chlorophyll accumulation but did not restore the lag. Addition of these inhibitors even 12 h after red light irradiation decreased the rate of chlorophyll accumulation. Rifampicin (Rifamycin SV, 400 μg ml−1) did not have such effects
