| Abstract:
Two Mediterranean species of genus Gladiolus were studied in order to diversify the range of ornamental plants on offer: G. illyricus for use as a rockery plant and G. italicum preferably for use as a cut flower, although it could be used in gardening. Both species can be sexually or asexually propagated, although seed production is higher than cormels production in both species. The growth and development characteristics of both species were tested both in their natural habitats and in an unheated greenhouse. Plants cultivated in the greenhouse grew faster and were larger. The length of the floral spike was also greater. The time elapsing to the onset of flowering was almost four months in G. italicus plants grown in the greenhouse and three months in G. illyricus. We suggest that more studies are necessary in order to understand the behaviour of these Gladiolus species whether grown in the open air or in the greenhouse. | |
