Abstract:
The present investigation was carried out to know the seed viability and germination percentage of celosia genotypes. Twenty genotypes of celosia were used for the study and GA₃@10 ppm was used as a growth regulator to stimulate the germination process. The experiment was conducted in Floriculture and Landscape Architecture department of Kittur Rani Chennamma College of Horticulture, Arabhavi. The experiment was laid out in Completely Randomized Design (CRD) and each treatment was replicated twice. The experiment was conducted in laboratory condition and the seeds were soaked in GA₃ @10 ppm in a transparent beaker and the seeds were sown in petridish along with germination paper. Highest germination speed was recorded in Celosia cristata var. Armor Red (64.5) this was followed by Armor Purple (58.5). Maximum seed test weight was recorded in T₂, T₃ and T₆ (8.5 g) and maximum germination percentage was recorded in T₂ (83%), shoot length was recorded in the genotype T₁₁ and T₁₇ (4.0 cm), root length was recorded in the genotype T₂₀ (3.1 cm), seedling length found highest in the genotype T₅ (6.9 cm) as well as seedling vigor was found highest in Celosia cristata var. Chief Carmine (448.6).
