Abstract:
The effect of foliar application of IAA, GA₃ and Daminozide on growth and flowering of gladiolus cv. Oscar was investigated. The field experiment was laid out in a randomized block design, replicated thrice, with three levels of each GA₃, IAA and Daminozide. The results revealed that foliar application of 100 ppm GA₃ was found to be the best for plant height (103.16 cm), number of leaves per plant (10.11), length of leaf (67.38 cm), days to first flowering (57.18 DAP), longevity of intact spike (18.44 days), length of the spike (99.67 cm), fresh weight of the spike (71.59 g), number of florets per spike (14.89) and vase life of the cut spike (12.33 days) followed by foliar application of 50 ppm GA₃. While the different levels of Daminozide reduced growth and flowering. However, foliar application of 500 ppm Daminozide increased longevity of intact spike following foliar application of 100 ppm GA₃.
