Mineral nutrition and growth of Eucalyptus seedlings

Seedlings of Eucalyptus delegatensis R.T. Bak., E. maculata Hook, and E. brockwayi CA. Gardn. were grown for up to 10 weeks in a solid rooting medium and flushed daily with one of five different nutrient solutions. Stable relative growth rates and internal nitrogen concentrations were established after an initial nutrient adjustment (lag) phase. Relative growth rate and relative nutrient uptake rate were directly related after the lag phase. Partitioning of assimilate to roots decreased from 0.35 (root weight/total weight) at low concentrations of nutrients, to 0.10 at high concentrations
