Low temperature sensing in tulip (Tulipa gesneriana L.) is mediated through an increased response to auxin.
Tulip (Tulipa gesneriana L.) is a bulbous plant species that requires a period of low temperature for proper growth and flowering. The mechanism of sensing the low temperature period is unknown. The study presented in this paper shows that the essential developmental change in tulip bulbs during cold treatment is an increase in sensitivity to the phytohormone auxin. This is demonstrated using a...
متن کاملThe lipoxygenase pathway in tulip (Tulipa gesneriana): detection of the ketol route.
The in vitro metabolism of [1-(14)C]linoleate, [1-(14)C]linolenate and their 9(S)-hydroperoxides was studied in cell-free preparations from tulip (Tulipa gesneriana) bulbs, leaves and flowers. Linoleate and its 9-hydroperoxide were converted by bulb and leaf preparations into three ketols: (12Z)-9-hydroxy-10-oxo-12-octadecadienoic acid (alpha-ketol), (11E)-10-oxo-13-hydroxy-11-octadecadienoic a...
متن کاملThe Effect of Different Concentrations of Gibberellic Acid on Quantitative and Qualitative Characteristics of Three Cultivars Lacourtine, Yokohama and Red Favourite Tulip (Tulipa gesneriana L.)
Tulip is one of the most important flowers to precocity. Treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. This study carried out about three tulip cultivars includes ‘Lacourtine’, ‘Yokohama’ and ‘Red Favourite’. The results showed that gibberellic acid reduced significantly stem l...

15 صفحه اولTemperature Regulation of Endogenous Gibberellin Activity and Development of Tulipa gesneriana L.
The changes in the contents of free and bound gibberellin-like activity (GA) of Tulipa gesneriana L. cv. Ralph during development under 2 temperature conditions were studied. The results show that the content of free GA of bulbs grown at 18 degrees increased by 67% over the initial level during development. The bound GA showed a slight initial increase and was followed by a rapid decrease. In c...
