Effect of Corm Size on Flowering Parameters in Gladiolus (Gladiolus Grandiflorus L.) cv. White Prosperity

An experiment entitled "Effect of corm size on flowering parameters in gladiolus (Gladiolus grandiflorus L.) cv. White Prosperity" was conducted during Rabi-Summer season of the year 2022-23 at College of Horticulture, Dapoli, Dist. Ratnagiri, (Maharashtra state). The experiment was laid out in Randomized Block Design with four replications and five treatments i.e., T1- Below 10 g, T2- 11-20 g, T3- 21-30 g, T4- 31-40 g and T5- 41-50 g. The results revealed that minimum number of days required for first spike emergence (65.10) and 50 per cent spike emergence (71.03), the highest spike length (72.36 cm), rachis length (51.17 cm), interfloret length (4.75 cm) and diameter of floret (8.11 cm) and maximum number of florets per spike (13.00), duration of flowering (11.95 days) and vase life (5.55 days) were recorded in treatment T5- 41-50 g. Thus, it could be observed from the results that, the corm size 41-50 g of gladiolus cv. White prosperity were found to produce superior flowering parameters in respect of early spike emergence, spike length, rachis length, interfloret length, diameter of floret, number of florets per spike, flowering duration.
