Lime-induced chlorosis in quince rootstocks: methodological and physiological aspects
1993
Viti, R. | Cinelli, F.
Two quince rootstocks for pear, clone MA and Ct.S.306, were screened to evaluate their threshold tolerance rate to lime-induced chlorosis. Another important objective was to correlate the results of a chlorophyll analysis with observed chlorosis symptoms. The iron content in leaves was insufficient to determine the amount of iron available to the plant. The use of sodium bicarbonate (NaHCO3) in the hydroponic culture of pear was found to be the preferable over calcium carbonate (CaCO3) because of its higher solubility.
