ThesisItem Restricted Varietal response of gladiolus to planting time for off season flower production(Punjab Agricultural University, Ludhiana, 2017) Chaudhary, Nidhi; Dhatt, K.K.The present investigation entitled “Varietal response of gladiolus to planting time for off season flower production” was undertaken in the field area of the Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, during 2015-2016. The corms of seven varieties of gladiolus namely Anglia, Punjab Lemon Delight, Alexander the Great, CPG, Punjab Glance, Sylvia and Novalux were planted at 15 days interval from 15th July to 15th October. The analysis of variance was conducted for plant growth, floral parameters and corm production as per Split Plot Design. Planting done on 15th July and 15th August took the maximum time to sprout i.e. 20.11 and 20.74 days, respectively, and the minimum time was recorded under 15th October planting (10.90 days). The minimum time for sprouting was recorded in variety Punjab Glance (8.87 days) while Sylvia took the longest time to sprout (21.27 days). First planting done on 15th July took longer time from corm sprouting to flowering (87.10 days). Total time from corm sprouting to flowering was recorded as 80.24 days under 1st August and 72.83 days under 15th August planting. Among the varieties, Anglia and Punjab Lemon Delight were early to flower which took 64.48 and 71.96 days, respectively. The plant height in early plantings of 15th July, 1st August and 15th August was recorded as 71.70, 79.34 and 79.59 days, respectively, which was comparatively less than late plantings. Similarly, the spike length in 15th July planting was the shortest (61.38 cm) bearing 7.95 florets per spike. Flower quality in terms of spike length (95.50 cm) and florets per spike (12.68) was recorded as the best in variety Alexander the Great. Variety Punjab Glance was recorded to have the biggest floret size (8.52 cm). The maximum flowering duration (15.58 days) was recorded under 1st September planting and in variety Alexander the Great (17.95 days). The maximum number of corms and cormels (1.63 and 18.88, respectively) were recorded under 15th October planting. The size of corms and cormels (4.05 cm and 1.93 cm) and weight of corms (43.85 g) was also recorded as maximum under 15th October planting. The maximum number of corms (1.59) were recorded in variety Novalux followed by Punjab Glance (1.50) while maximum corm size (3.85 cm) and corm weight (41.00 g) was recorded in variety Alexander the Great. The maximum cormel number (33.92) per plant was recorded in variety Punjab Glance while maximum cormel size (1.87 cm) was recorded in variety CPG. The vase life of 10.31 days was recorded as the longest under 1st October planting. Amongst the varieties, the longest vase life of 10.51 days was recorded in variety Alexander the Great followed by variety Punjab Glance (10.04 days).
