Analyse spectrophotométrique du phytochrome dans l'embryon de Courge (Cucurbita pepo) et de Potiron (Cucurbita maxima)

Abstract

Phytochrome detection and △ (△O.D.) measurements were made for the first time in a single embryo of pumpkin or gourd thanks to an apparatus adjusted to the differential spectrophotometer constructed by Dr. Spruit (Wageningen). Observed △ (△O.D.) values are comparable with usual values obtained by analysis of several seeds in a cuvette. The differential… (More)
