Abstract

Research Note

One-year-old cuttings from 7 Vitis species (V. amurensis Rupr., V. berlandieri Planch., V. californica Bentham, V. cinerea Engelm., V. longii Prince, V. monticola Buckl., V. riparia Michx.) were grown in pots containing non-calcareous and calcareous soil. Leaves selected in the middle of the second year's growing season were assayed to test the iron concentration of the dry matter and the total iron uptake. The most significant findings of the trial were:
a) shoot growth of V. amurensis, V. longii, V. monticola and V. riparia was strongly depressed by the calcareous soil;
b) V. berlandieri and V. californica took up higher amounts of iron when growing in the calcareous soil;
c) a high ash alkalinity occurred in chlorotic leaves of V. riparia compared to non-chlorotic leaves at the same iron concentration.
