Abstract
Breeders and Researchers need information for selecting and improving gerbera flower as promising cut flowers through flower color analysis. This experiment was accomplished to accurately define the different flower color cultivar and analysis of flower color of gerbera in the Horticulture farm of Sher-e-Bangla Agricultural University during the period of January, 2017 to June, 2017. Fourteen gerbera cultivars were used in this experiment arranged in Randomized Complete Block Design with three replications. The gerbera cultivars have been classified based on peduncle length and diameter, receptacle diameter, ray floret diameter, trans floret diameter, disc diameter, flower head type, disc color, flower shape, flower per plant and floret color following UPOV authorized guidelines. The color of the gerbera cultivars were definitely measured and expressed through L* (lightness), a* and b* (two Cartesian coordinates) including C* and hab (Chroma & Hue angle) based on CIELab scale. Classification and variation in petal color attributes presented in tables and plates that may be used for further research to improve the flower sector.
Highlights
Flowers have been regarded as the icon of beauty and food for our sight
Classification of Gerbera cultivars Classification of Gerbera according to the peduncle length Gerbera cultivars were divided into three classes according to the length of peduncle following the UPOV standard
Classification of Gerbera according to the trans floret diameter Head of gerbera cultivars was divided into three classes according to the trans floret diameter following the UPOV standard (Table 03)
Summary
Flowers have been regarded as the icon of beauty and food for our sight. Flower boosts the visual sense of human beings and meets the requirement of heart feelings. Contribution of market share of gerbera flower is only 0.64 percent and the retail revenue was 0.6 million USD (USAID, 2014). Characterization and petal color analysis of Gerbera cultivars market share and production place is still far away from national demand. Local varieties had lower yields than hybrids, some hybrids are poor in quality, some were best in both quality and quantity and some hybrids presented similar yields (Yama et al, 2006). According this consideration, researchers and breeders should conduct study to observe the varietal activities of gerbera in Bangladesh. This study was conducted to classify fourteen gerbera cultivars under the study into different grouped following UPOV standard and measurement of petal color with colorimeter
