Abstract/Description: | Gladiolus (Gladiolus (Tourn) L.) is an important bulbous cut flower crop, known for its longer vase life and exhaustive range of colours. Gladiolus cultivars American Beauty and Snow Princess were grown at different temperature and carbon dioxide (CO2) levels under phytotron condition at Indian Agricultural Research Institute, New Delhi (India) during 2009- 2010. Temperature treatments given were 20/18 ºC (control), 26/24 ºC and 30/26 ºC (day/night) while CO2 treatments studied were 400 ppm (control), 700 ppm and 900 ppm. The results indicated that at higher temperature, there was significant reduction in fresh weight of cut spike at harvest. Senescence was accelerated by increased temperature. There were small differences in vase life, in which the gladiolus plants grown at 20/18 ºC lasted significantly longer (12.40 day) than plants grown at 26/24 ºC (9.53 day) in cultivar Snow Princess. Spike length, water uptake and diameter of first and third florets decreased with increase in temperature level. At 30/26ºC temperature, spike initiation did not take place in both the cultivars studied. Different CO2 levels had significant effect on fresh weight and vase life of cut spikes. As CO2 concentration increased, there was significant increase in fresh weight of cut spike. The maximum fresh weight of cut spike (73.07 g) was obtained in 700 ppm CO2 concentration. Spike length was increased with increase in the CO2 concentration. Vase life was also increased as the CO2 concentration increased and maximum was observed in 700 ppm (12.97 day). |
