The Study of the Main Anatomo-Morphological and Decorative Characteristics of the Gladiolus hybridus Approved for Fruit Research Station Cluj in 2008

Abstract

The genetic potential of the species Gladiolus hybridus offers the possibility for the continuous diversification of the assortment of flowers by breeding new cultivars, important from the point of view of their decorative value, as well as economically. In the year 2008, other 2 valuable cultivars, Medina and Coral Passion were added to the list of homologated cultivars belonging to this species (28 cultivars) at the Fruit Research Station of Cluj. Biometrical observations were done concerning the following traits: plant height, floral stem length, the length of the inflorescence, number of flowers/inflorescence and flower size. Other traits taken into study were: the colour of the flowers, the number of flowers open at the same time, resistance to pests and diseases and the vase life of the flower stem. The experimental data were interpreted statistically, by calculating the averages and the significance of the differences was tested by using the DL test. The parental cultivars, Priscilla and Nova Lux were used as controls and comparative studies were done regarding the main characteristics that were taken into study. By analyzing the results obtained in the 3 years of study it is observed that the 2 homologued hybrids are remarkable for: the flowers colours, which is very good for both hybrids, superior values as compared to the parental cultivars have been registered regarding the traits.
