the effect of gibberellic acid (ga3) spraying on some characteristics of cyclamen flowering trend during the second flowering year was investigated. ga3 sprays were applied in concentrations of 0, 20, 30, 40, and 50 mg/l. the trial was carried out as a randomized complete design of three replications. the total flower count, flower count during the flowering peak, days from spraying to flowerin...
gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...
Phyllody is a flower abnormality in which leaf-like structures replace flower organs in all whorls. Here, we investigated the origin and the molecular mechanism of phyllody phenotype in Rosa chinensis cv. Viridiflora, an ancient naturally occurring Chinese mutant cultivar. Reciprocal grafting experiments and microscopy analyses, demonstrated that the phyllody phenotype in Viridiflora is not ass...
Flowering is one of the important defining features of angiosperms. The initiation of flower development and the formation of different floral organs are the results of the interplays among numerous genes. But until now, just fewer genes have been found linked with flower development. And the functions of lots of genes of Arabidopsis thaliana are still unknown. Although, the quartet model succe...
variation in the essential oil of artemisia annua l. apical shoots at different developmental stages
artemisia annua is a medicinal annual herb that widely distributed in asia, europ, north america, and also is grown in north reagions of iran. in this study, variation in the quantity and quality of the essential oil of a.annua apical shoots at different developmental stages including vegetative, early flower opening and full flowering stages is reported. the obtained oils by hydrodistilation o...
Muscari armeniacum is one of the important ornamental cut flower in floriculture industry which native to Southern Europe, North Africa, Western Asia and Asia Minor. In this study, bulb explants (basal plate of bulb having meristem), bulb scales and leaf segments from in vitro derived bulblets were culture in Murashige and Skoog (MS) medium with different plant growth regulato...
In Brassica napus, floral development is a decisive factor in silique formation, and it is influenced by many cultivation practices including planting date. However, the effect of planting date on floral initiation in canola is poorly understood at present. A field experiment was conducted using a split plot design, in which three planting dates (early, 15 September, middle, 1 October, and late...
Flower bud formation and flowering in chrysanthemums occur under short day conditions (SD), but the molecular basis for the switch to reproductive growth is less well understood than in model plants. Here, a spontaneous mutant able to flower under long days is described. In an attempt to reveal the pathway(s) involved in the formation of flower buds under contrasting daylengths, transcriptome s...
