Vegetative propagation of gladiolus: influence of exogenous gibberellic acid application and division of the mother corm


, : Vegetative propagation of gladiolus: influence of exogenous gibberellic acid application and division of the mother corm. Anales del Instituto Nacional de Investigaciones Agrarias, Agricola (27): 29-45

Corms of cultivars Peter Pears and White Goddess were (A) notched at the base through the basal plate, (B) divided into 4 sections, (C) divided into 8 sections, or (D) soaked for 24 h in a 500 p.p.m. GA solution. Substrates differing in organic matter content, air volume and porosity were evaluated. The number of cormels produced was similar with all treatments but cormel weight was higher with treatments C and D. Yields of grade I corms (4-8 cm diameter) were highest with treatments B and C.
