The programmed degradation of macromolecules during petal senescence allows the plant to remobilize nutrients from dying to developing tissues. Ethylene is involved in regulating the timing of nucleic acid degradation in petunia, but it is not clear if ethylene has a role in the remobilization of phosphorus during petal senescence. To investigate ethylene's role in nutrient remobilization, the ...

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 ...

Generally, Asteraceae flowers such as chrysanthemums and gerberas, are low ethylene-sensitive do not exhibit petal wilting abscission. However, previous research found that the of dahlia, an member belonging to tribe Coreopsideae, show abscission layer development in petal-ovary boundaries. In this study, we investigated ethylene sensitivity 17 ornamental species different tribes by measuring d...

ABSTRACT- Chrysanthemum (Dendranthema grandiflorum) is one of the most important ornamental plants used as cut flower, flowering pot plant and groundcover worldwide. In this research, the effects of preservative solutions containing thymol (75 and 125 mg -L), menthol (75 and 125 mg L-1) and eugenol (75 and 125 mg L-1) on the quality and vase-life of chrysanthemum cut flowers at 3±1ºC and 75-80%...

Foxtail lily (Eremurus), as a medicinal-ornamental geophyte, has recently emerged in the cut flower market novel, commercially significant specialty (SCF). However, there is limited information about sensitivity to ethylene of foxtail species for managing ethylene-mediated senescence prolong vase life and maintain ornamental quality this flower. The purpose current study was compare production ...

ILD Gossypium anomalum Wawrs. and Peyr. among Gossypium species whas anomalous petal spot inheritance. Its petal spot involves two independently inherited genes; a ghost spot gene interacts with a spotless gene making a large anthocyanin area at the base of a petal (SILOW 1941). In the two cultivated Asiatic diploid species red petal spot involves three closely linked genesmargin. ghost spot, a...
