Abstract


Evaluation of quantitative and qualitative floral characters of seven indigenous sympodial epiphytic orchids of Western Ghats was conducted at the Department of Floriculture and Landscape Architecture, College of Agriculture, Vellanikkara during 2019-2020. The study evaluated quantitative and qualitative floral characters of indigenous sympodial epiphytic orchid accessions such as Dendrobium densiflorum, D. fimbriatum, D.ovatum, D.crumenatum, D. moschatum, Eria fragrans and Pholidota imbricata. Significant variation was observed with respect to floral characters of orchid accessions studied. The accession P.imbricata (VKA/ NOR-29) recorded the highest spike length (49.66 cm) and number of florets per spike (63.33). The largest showy flower among the accessions was observed in D.moschatum (VKA/NOR-37) with a maximum flower size of 54.37 sq.cm. Wide variation was also observed with respect tospike orientation, petal shape, petal curvature, lip shape and colouration of flowers. Among the accessions, fragrant flowers were noted in D.crumenatum (VKA/NOR-34), D. fimbriatum (VKA/NOR-27), D.moschatum (VKA/NOR-37) and E.fragrans(VKA/NOR-25).
