Quality and Quantity Characteristics of Two Gladiolus Cultivars (Gladiolus grandiflorus cv. White Prosperity and Ruse Supreme)

Storage conditions influence quality of gladiolus corms which thereby affects quality of flowers. In the present study، the effects of pre-storage curing and different temperature conditions on corm germination and various vegetative and reproductive growth parameters of Gladiolus grandiflorus cv. White Prosperity and Gladiolus grandiflorus cv. Ruse Supreme were studied. Application of pre-storage curing with one or two months of cold treatment 50C resulted in the best dormancy release and faster bolting. These corms produced better plant and cut flower quality. The elongation of flowering shoot and flowering delayed when the corms stored at 50C for the whole storage period، but produced good quality cut flowers، showing interruption of dormancy release. In the other hand، the corms stored during whole storage period at 130C had lower and longer plant emergency and produced lower quality plants and flowers. This shows that dormancy release was not completed. The corms stored in noncontrolled temperature room showed growth and production characteristics between these two categories. The observation and data for both cultivars showed the same tendency.
