Growth characteristic of Welsh onion (Allium fistulosum L.) grown from seeds and transplants

Abstract

The characteristic growth features of four Welsh onion cultivars (‘Parade’, ‘Performer’, ‘Siedmiolatka Zielona’, and ‘Siedmiolatka Czerwona’) dependant on growing method (seeds sown directly in the field and from transplants) were evaluated during the three-year study (2007-2009). The following traits were determined: plant height, number of leaves on a single plant, tendency to produce laterals, plant weight, as well as length and diameter of the pseudostem. Plants of the ‘Parade’ cultivar were the highest (76.0 cm, on average), while those of ‘Siedmiolatka Czerwona’ were the shortest (mean 68.6 cm). Pseudostem length was found to be the main factor determining the height of the Welsh onion. The longest pseudostems were observed for the ‘Parade’ and ‘Performer’ cultivars, while the ‘Siedmiolatka Czerwona’ had the shortest.
