gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. to increase vase life of gerbera cut flowers cv. ‘alain ducasse’, the essences of eucalyptus and rosa damascena, the combination of these two essences at a concen...
Chalcone synthase (CHS) is a key enzyme in the biosynthesis of flavonoids, which are important for the pigmentation of flowers and act as attractants to the pollinators. Genes encoding CHS constitute a multigene family in which the copy number varies among plant species and functional divergence appears to have occurred repeatedly. Plants of the Dendranthema genus have white, yellow, and pink f...
Reports of boron (B) deficiency have become more prevalent in pansy (Viola ×wittrockiana), petunia (Petunia ×hybrida), and gerbera (Gerbera jamesonii) plug production. When symptoms are observed in production the presence and severity of symptoms have no obvious pattern; symptomatic plants can be located adjacent to asymptomatic plants in the same plug flat. The availability of B in the soil de...
This study was arranged to evaluate the effects of perlite-cocofibre substrate inoculation as the most prevalent media in gerbera soilless cultivation with two important arbuscular mycorrhizal fungi (AMF: Glomus intradices and Glomus mossea) on morphological, physiological and quality attributes of gerbera cut flower. Results showed the positive symbiosis between AMF and gerbera ('Stanza'), and...
Drought is a key abiotic stress that confines agriculture development worldwide. Silicon (Si) commonly considered to be valuable element for resistance against drought and sustainable agriculture. To investigate the morpho-physiological biochemical characteristics of Gerbera jamesonii plants, pot experiment was conducted under greenhouse conditions exposed water (60% FC) well-watered (100% cond...
Abstract This work aimed to investigate the interaction between salt stress and application of silicon dioxide-nanoparticles. In this study, gerbera plants grown in soilless culture were supplied with nutrient solutions different NaCl concentrations (0, 5, 10, 20 30 mM) combination SiO 2 -NPs spray 25 50 mg · L −1 ). Exposure salinity increased sodium concentration but decreased potassium calci...
The molecular mechanisms that control organ shape during flower development are largely unknown. By using differential hybridization techniques, a cDNA designated GEG (for Gerbera hybrida homolog of the gibberellin [GA]-stimulated transcript 1 [GAST1] from tomato) was isolated from a library representing late stages of corolla development in Gerbera. GEG expression was detected in corollas and ...
