Response of different varieties of gladiolus (Gladiolus grandiflorus L.) for post-harvest parameters

The present investigation entitled “Response of Different Varieties of Gladiolus (Gladiolus grandiflorus L.) for Post-Harvest Parameters” was conducted during February 2021-March 2021 at the Department of Floriculture and Landscape Architecture, K.N.K. College of Horticulture, Mandsaur (M.P.). The experiment was laid out in a completely randomized design with three replications and used nine varieties of gladiolus viz. V₁ (Arka Darshan), V₂ (Arka Gold), V₃ (Arka nazrana), V₄ (Green Star), V₅ (Jyotsana), V₆ (Psittacinus), V₇ (Punjab Dawn), V₈ (Pusa Kiran) and V₉ (Yellow Stone). The result revealed that Yellow Stone recorded the best performance with respect of most of the post-harvest parameters i.e. fresh weight of spike (47.00 g), floret length (8.91 cm), rachis length at harvest (48.90 cm), rachis length at senescence (51.50 cm), longevity of 3^rd floret (4.42 days), longevity of 5^th floret (4.47 days) and percentage of open floret (88.30 %). The maximum floret diameter (10.21 cm), solution uptake at 5^th days (73.75 ml), days taken to opening of 5^th floret (5.42 days) and dry weight of spike (6.11 g) was recorded with cv. Arka Gold. The maximum solution uptake at senescence (111.67 ml) & number of open floret (11.92 florets) was recorded with cv. Jyotsana while shortest duration required to days taken to opening of last floret (8.67 days) was recorded with cv. Psittacinus. Punjab Dawn shower the best performance with vase life (13.33 days) of gladiolus spike.
