Abstract
Abstract Plant height, number of leaves, diameter and fresh weight of the bulbs, and the dry weights of the component plant parts of 3 onion cvs were measured weekly, starting 40 days after transplanting, up to maturity. Red Kano had singificantly more leaves, greater leaf area, larger bulbs and fresh and dry weights than Eclipsel Bermuda and Texas Grano. Net Assimilation Rate (NAR), Relative Growth Rate (RGR), and Relative Leaf Growth Rate (RLGR) were generally high in the early stages of growth in all cvs and declined with plant age. Red Kano had much higher values than the other two. Crop Growth Rate (CGR) of tops was positive in the early stages of plant growth in all the cvs but decreased to negative values towards maturity which was due to a decrease in the dry weight of the leaf blades caused by decrease in leaf number. Red Kano and Texas Grano showed positive values throughout the experimental period. The higher CGR for the bulbs as compared to the blades was due to large quantities of carbohydrates which were translocated to the bulbs. Leaf Area Ratio (LAR) was constant in Red Kano , due to proportionate increase in leaf blade area and weight. Results of all the growth characteristics showed that Red Kano was superior to the other cvs in attaining a larger bulb size due to large number of leaves and longer growing season, resulting in the translocation of more carbohydrates to the bulbs.
