    Notes: Summary Effects of zinc supply on shoot and root dry weight, root length, zinc concentrations and carbonic anhydrase activity were measured in 52 day old seedlings ofEucalyptus maculata, E. marginata, E. patens and wheat grown in a zinc deficient soil in the glasshouse. Symptoms of zinc deficiency in the eucalyptus and wheat appeared within 20 to 35 days. Eucalypt seedlings had short internodes and small necrotic leaves, reduced dry weight of shoots and roots, root length and zinc concentrations in young leaves; the measurable level of leaf carbonic anhydrase activity decreased to zero. Similar responses also occurred in wheat. The level of zinc fertilizer required for normal growth of Eucalyptus seedlings is therefore likely to be similar to that used for wheat and other agricultural crops.

    Zinc nutrition and leaf carbonic anhydrase activity ofEucalyptus maculata seedlings andTrifolium subterraneum (1989)

    Notes: Abstract Carbonic anhydrase activity in selected leaves was examined in relation to zinc supply toEucalyptus maculata seedlings andTrifolium subterraneum grown in the glasshouse on a zinc-deficient sand. In both species, carbonic anhydrase activity was closely related to the zinc supply and fell to 0 in severely-deficient plants. Enzyme activity increased linearly as a function of the leaf zinc concentration. InE. maculata plants supplied with adequate zinc, carbonic anhydrase levels were only 3% of those inT. subterraneum. It is concluded that foliar zinc analysis is more sensitive than the carbonic anhydrase assay for determining the zinc status ofE. maculata seedlings. Critical zinc concentration for young fully-expandedE. maculata leaves was between 9 and 10 μg g−1 dry matter.
