Spectral sensitivity of the flowering response in green and etiolatedLemna paucicostata T-101

摘要

Light sensitivity in the reversal of the far-red inhibition of flowering in etiolatedLemna paucicostataT-101 was 10- (612 nm) to 33-fold (660 nm) higher than that of green plants. The action spectrum of this response for etiolated plants showed a peak near 660 nm, but for green plants it was near 612 nm. Thus, the effect of light on flowering is influenced greatly by the screening effect of photosynthetic pigments.
