Effect of Plant Growth Regulators and Micronutrients on Vase Life Characters of Gladiolus (Gladiolus Grandiflorus L.)

The investigation was conducted to find out the effect of plant growth regulators and micronutrients on vase life characters of gladiolus (Gladiolus grandiflorus L.) cv. Novalux. The experiment was conducted in factorial randomized block design with 12 treatments replicated thrice at the main Experiment Station, Department of Floriculture & Landscape, Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya. The plant growth regulators and micronutrients application significantly influenced the vase life of gladiolus. The maximum per cent increase in spike length, per cent opening of floret per spike, number of florets opened at a specific time and vase life (days) was noted in CCC 500 ppm with ZnSO₄ 0.5% + FeSO₄ 0.2%. The minimum drooping of florets was obtained with the combinations of CCC 500 ppm with ZnSO₄ 0.5% + FeSO₄ 0.2%. and maximum observed under control.
