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 کاملEffect of Benzyladenine and Gibberellic Acid on Dormancy Breaking, Growth and Yield of Gladiolus Corms over Different Storage Periods
A study was conducted to determine the optimum concentration of benzyladenie (BA) and gibberllic acid (GA3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of BA and GA3 on growth and development of gladiolus corm and cormels. The effect of GA3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...
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 کاملeffects of temperature, ga3 and cytokinins on breaking seed dormancy of ferula assa-foetida l
ferula assa-foetida l. (apiaceae) is one of the most important endangered medicinal plants,which is rare in nature due to poor seed germination. in an effort to improve and promote the cultivation ofthis plant, the effects of two temperatures (23°c and 4°c), exogenous ga3 and cytokinins (kinetin and bap)were investigated on dormancy breaking and germination of f. assa-foetida l. seeds. among th...
