Vegetative growth, yield and quality parameters of daisy (Aster amellus L.) as influenced by gibberellic acid and genotypes

An experiment was carried out in the experimental field of department of Floriculture and Landscape Architecture, KRC College of horticulture, Arabhavi, to know the performance of daisy genotypes for foliar spray of gibberellic acid. Gibberellic acid spray at 150 ppm helped for influencing the vegetative growth parameters and yield parameters. Among the genotypes purple multipetal produced maximum vegetative growth and genotype star white daisy produces maximum suckers per plant. The genotype dwarf pink was found to be early to flowering. The flower yield was maximum in genotype white tall, followed by purple long petal, purple multipetal and dark purple. The spike length was maximum in genotype purple multipetal. Whereas, in interaction V₁G₁, V₁G₂ performed best for vegetative growth parameters. However, V₂G₁ and V₂G₂ produced maximum leaves per plant. The sucker production was maximum in V₅G_1.
