Role of cytokinins in carnation flower senescence.
Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...

Wu, M.J., Zacarias, L. and Reid. M.S., 1991. Variation in the senescence of carnation (Dianthus cao,ophyllus L.) cultivars. II. Comparison o f sensitivity to exogenous ethylene and of ethylene binding. Scientia Hortic., 48:109-116. Flowers o f the 'Sandra' and "Chinera" cultivars o f carnation (Dianthus caryophyllus L. ) last about twice as long ( 14 days) as those o f 'Whi te Sim' cultivar (7 ...
متن کاملRole of the Ovary in Carnation Senescence
Mot, Y., Reid, M.S. and Kofranek, A.M., 1980. Role of the ovary in carnation senescence. Scientia Hortic., 13: 377--383. Ovary growth in carnation flowers was inhibited by pre-treatments with silver thiosulfate which retarded petal senescence. Although the start of ovary growth preceded visible wilting of untreated flowers, the ovary does not appear to control carnation senescence. Its removal ...
متن کاملAcceleration of Membrane Senescence in Cut Carnation Flowers
The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporaDly with petal-inroDling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...
متن کاملAntisense ACC Oxidase RNA Delays Carnation Petal Senescence
The phytohormone ethylene is essential for senescence in many fruits and flowers. In the biosynthesis of ethylene in plants, the conversion of S-adenosyl methionine (SAM) to 1-aminocyclopropane1-carboxylic acid (ACC) and the conversion of ACC to ethylene are catalyzed by ACC synthase (ACS) and ACC oxidase (ACO), respectively (Adams and Yang, 1979). Using a cDNA clone representing carnation ACO ...
