Gladiolus hybridus ABSCISIC ACID INSENSITIVE 5 (GhABI5) is an important transcription factor in ABA signaling that can enhance Gladiolus corm dormancy and Arabidopsis seed dormancy
The phytohormone abscisic acid (ABA) regulates plant development and is crucial for abiotic stress response. In this study, cold storage contributes to reducing endogenous ABA content, resulting in dormancy breaking of Gladiolus. The ABA inhibitor fluridone also promotes germination, suggesting that ABA is an important hormone that regulates corm dormancy. Here, we report the identification and...
متن کاملInfluence of phosphorus fertilization on gladiolus corm and flower production
The influence of different levels of phosphorus on corm and flower productivity of Gladiolus (Gladiolus grandiflorus) was studied at Faculty of Agriculture Rawalakot, Azad Jammu and Kashmir during the year 2010. Corms of similar size and weight were collected from Awan Nursery and Seed Store, Rawalpindi. Sowing was done on 25 April, 2010 with five different phosphorus levels viz. 40, 70, 100, 1...
متن کاملThe effect of dormancy on glucose uptake in gladiolus cormels.
The uptake of glucose and of 3-O-methyl-d-glucose by cormel slices of Gladiolus X gandavensis Van Houtte was studied in relation to cormel dormancy. Uptake was higher in nondormant cormels. Incubation of nondormant cormels with abscisic acid (ABA) reduced their uptake capacity. Treatment of dormant cormels with 6-benzyladenine (BA) did not affect their uptake rate. ABA and BA promoted O(2) upta...
متن کاملHumic acid and cultivar effects on growth, yield, vase life, and corm characteristics of gladiolus
Gladiolus (Gladiolus grandiflorus L.), a popular and economically profitable bulbous cut flower, has high demand in both Pakistan domestic and international markets on account of its attractive spikes, florets of huge forms, dazzling colors, varying sizes, and long vase life. However, its quality production is badly affected by non-uniform sprouting, poor crop stand, and old cultivars. To overc...
متن کاملDark CO(2) Fixation in Gladiolus Cormels and Its Regulation during the Break of Dormancy.
The increase in dark CO(2) fixation during cold storage of Gladiolus x gandavensis van Houtte-type grandiflorus cormels is used to monitor changes in their state of dormancy. Dark fixation is also promoted by benzyladenine, which breaks cormel dormancy, and is inhibited by abscisic acid and gibberellin A(3), which inhibit cormel germination. The rate of dark fixation by nondormant cormels is fi...
