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).
