摘要

In-vivo phytochrome determinations in totally etiolated rice seedlings with a dual-wavelength spectrophotometer showed that on a fresh weight basis phytochrome concentration was highest in the coleoptile apex (0.175 of mean) Δ(Δ O.D.) g-1(fresh weight). The age of the seedlings had little effect on the pattern of phytochrome distribution in the coleoptile
