The timing of inflorescence degreening is altered by hormone application. Landsberg erecta (Ler-0) inflorescences were detached and placed in the dark for 3 d with their cut ends in water or in solutions containing 100 μm 6-benzylaminopurine (BAP) or 100 μm ABA. Mean chlorophyll levels (as a percentage of day 0 [D0]) are shown for five replicates at day 3. Error bars are 95% confidence intervals for the mean. ***Treatments were significantly different from the Landsberg erecta untreated control (P < 0.001).
