Efecto de atomizaciones con ácido giberélico, urea y azúcar, sobre la asimilación neta y el hábito de crecimiento del frijol

Abstract

Increase Gibberellic Acid increased net assimilation rate, velative growth rate, stem dry weight, leaf area, and plant height Root dry weight was reduced and leaf dry weight was not significantly altered. Reduction in root dry weight induced by gibberellic acid could be effectively controlled by 10% sucrose sprays. in net assimilation vate (photosynthesis) caused by gibberellic acid seemed to result from a more rapid translocation of photosynthates from the leaves to the stem. Urea sprays increased stem elongation of plants receiving gibberellic acid. Both sugar and gibberellic acid were effective to protect against injury by 2% urea spray.
