Abstract
This study was carried out under greenhouse conditions with the aim to evaluate the effect of the K+/Ca2+ ratios contained in the nutrient solution on the nutrimental status of tulip cv. Ile de France. We tested three potassium levels (5.5, 7.0 and 8.5 molc m-3) and three calcium levels (7.5, 9.0 and 10.5 molc m-3) in the nutrient solution in a 32 factorial experiment.
The combination of factors (K+ and Ca2+) and levels of factors resulted in nine treatments.
Antagonistic effects of K+ and Ca2+ were evident.
However, low Ca supply in the nutrient solution produced a higher Ca uptake by the plant; the same response was observed with K by supplying low levels of it.
Nutrimental analyses indicate that Ca partitioning is higher in leaves and stems, while K is more abundant in bulbs.
