Effect of gibberellic acid on photoperiod controlled growth in seedlings of black currant (Ribes nigrum L.)


, : Effect of gibberellic acid on photoperiod controlled growth in seedlings of black currant (Ribes nigrum L.). Acta Horticulturae (34): 151-155

Black currant seedlings grown under daylengths of 8 or 12 h were very dwarfed in habit compared with those grown under daylengths of 16 or 20 h. Weekly sprays of 250 p.p.m. GA3 were ineffective in promoting appreciable elongation of the main stem in short days, although they strongly increased lateral branching.
