Abstract

Gladiolus (Gladiolus grandiflorus Hort.) is a commercially important open field crop, cultivated for elegant spikes. The development rate is dependent upon temperature so planting date is crucial factor to regulate flower production around the specific days. The present investigation was to validate the application of PhenoGlad model on different varieties grown in Punjab, India so that it could be used as a management tool for meeting market requirements. Five varieties of gladiolus with different developmental cycles were procured from Department of Floriculture and Landscaping, PAU, Ludhiana and planted at monthly interval from September to December at the research farm of Department of Floriculture and Landscaping, PAU, Ludhiana. Punjab Lemon Delight and Punjab Glance took minimum days to reach phenostages whereas Punjab Glad 3 and CPG took maximum days and White Prosperity took intermediate days under all planting dates. Observed days to reach a particular phenostage in our results was close to simulated days under October planting for Punjab Lemon Delight, Punjab Glance and White Prosperity and November planting for Punjab Glad 3 and CPG. Thus, these results validated the use of PhenoGlad model to simulate flowering time of different varieties to regulate the market demand.
