Studies on allometric growth relationships of sugar beet(Beta vulgaris) grown in nutrient culture

The effects of genotype and seed size on the growth of sugar beetseedlings in liquid nutrient culture medium were examined. Seed size waspositively correlated to seedling weight at the 5/7-leaf stage of developmentbut had little influence on mean total root to shoot ratio. At the 8-leaf-stagethere was considerable variation in the fibrous root to shoot ratios betweenindividuals in each of three cultivars. Nevertheless, the mean root to shootratio of seedlings of each cultivar was relatively similar. However, largegenotypic differences were detected in the depletion of specific elements fromthe nutrient culture solution, this being particularly so for nitrogen,potassium and sodium.
