摘要

Onion originated in Iran and its neighboring countries. Dependent on climatic conditions, this crop is cultivated in the Southern region of Iran during spring or autumn. Most onions are short day cultivars. In order to elucidate the characteristics ofthese South Iranian cultivars, a field experiment was conducted at Shahid Chamran University in Autumn, 2002. In this experiment, 12 cultivars ('Ramhormozy', 'Bl', 'Ghermaz Azarshahar', 'Daaman', 'P80', 'Shahdad', 'Bardseer', 'Sarkareh', 'Primavera', 'Texas Yellow Grano', 'Texas Early Grano', 'Gl'), which are cultivated in southern regions, were sown under a randomized block design with three replications. During growth and development different morphology characteristics, viz. plant height, number ofleaves per plant, bulb diameter, neck diameter, bolting percentage, average bulb yield, weight and number of storage leaves of different cultivars were recorded. Maximum plant height was recorded for 'Ghermaz Azarshahar' cultivar 16 days after emergence.This cultivar exhibited earlier and more uniform emergence than others. However 'Primavera' dominated all other characteristics under study during the transplanting stage of growth, but was equated by 'P80' in some characteristics. The effect of stressbrought about by transplanting impeded the growth of seedlings for a month. After transplanting stress, the leaf area exhibited a 100 to 200% increase daily in March with the onset of optimum growth conditions from 10 February, to 20 March. Concerning photoperiod sensitivity of cultivars leaf and leaf area production rate decreased from 21 March to 10 April. The reaction of non-native plant cultivars was inconsistent. Some of them produced a floral stem and seed, while others produced a bulb. Maximum and minimum yields were recorded for 'Gl' and 'Primavera', respectively. Among early maturing varieties 'P80' produced the maximum number of bulbs.
