In the present investigation entitled “Regulation of flower senescence ethylene insensitive
gladiolus” (Gladiolus grandiflora Hort.), gladiolus flowers which are ethylene insensitive were
used as a system to investigate the physiological and biochemical changes associated with activity
of antioxidants both enzymatic and non enzymatic, protein degradation and protease activity, and
lipid peroxidation and lipoxygenase activity during ethylene independent floral senescence.
Thirty gladiolus varieties were evaluated for their keeping quality in the field (Field life) and also
under laboratory conditions (in vitro) during 2010-11 in the research farm of Directorate of
Floricultural Research, New Delhi. It was found that the varieties, Big Time Supreme and
Jackson Ville Gold recorded maximum keeping quality in terms of field life and vase life in the
laboratory (15.67, 13.67 days and 13.67, 12.67 days, respectively). Minimum keeping quality was
observed in the varieties Purple Flora (7.33 and 5.67 days) and White Prosperity (8.00 and 6.33
days). The protease activity was reduced with the treatment of protease inhibitors maximum
reduction being with the use of 5-SSA. Similarly the protein content was maximum in the
treatment with 5-SSA. There was a strong negative correlation between the protease activity and
protein content with the use of protease inhibitors.
