Partial results regarding the behavior of some ornamental varieties of Ipomoea batatas cultivated within the ecological conditions of Iaşi

Abstract

The genus Ipomoea includes annual and perennial species, some of which are cultivated for ornamental purposes. Ipomoea batatas is a perennial species, grown as an annual in unprotected conditions. In this paper, the behavior of four cultivars of I. batatas ('Rusty Red', 'Midnight Lace', 'Light Green' and 'Purple Hearts'), cultivated in the experimental field of the discipline of Floriculture at the Iasi University of Life Sciences, Romania, was evaluated. Observations and determinations made after 35 days of establishment of cultures revealed differences between cultivars in terms of number of leaves/plant, shoots length and leaf size. The highest number of leaves and the longest shoots were recorded on the variety 'Rusty Red', while the variety 'Midnight Lace' stood out for the largest size of the leaves.
