Comparisons of early growth of tissue culture clones and seedlings of Eucalyptus camaldulensis indicated strong morphological differences between genotypes within the species, but no architectural differences, either above-or below-ground, were attributable to micropropagation. Clonal 9-month-old plants were less variable than seedling populations. Both seed-origin plants and clonal-origin plants generally developed a number of deep sinker roots and showed equal ability to penetrate heavy clay soils. One clonal line, however, had a compact habit and a root architecture concentrated in the upper 20 cm of the soil profile. Under favourable nutrient and water conditions, the largest of the 9-month-old plants from both seed and tissue culture exceeded 2.5 m in height, produced more than 500 g of above-ground biomass and developed root lengths exceeding 8 km. Clonal Eucalyptus camaldulensis have advantages in plantation conditions with saturated, saline and heavy soil conditions.
