Lanthanum delays senescence and improves postharvest quality in cut tulip (Tulipa gesneriana L.) flowers.

We tested two sources of lanthanum (La), LaCl and La(NO) × 6HO at a concentration of 40 µM each, in the treatment solution of cut flowers of 15 tulip (Tulipa gesneriana L.) cultivars. Ascorbic acid (AsA; 0.

Lanthanum Prolongs Vase Life of Cut Tulip Flowers by Increasing Water Consumption and Concentrations of Sugars, Proteins and Chlorophylls.

We evaluated the effect of separately adding two sources of lanthanum (La), LaCl and La(NO) × 6HO at a concentration of 40 µM each, to the preservative solution of 15 cut tulip flower varieties. Ascorbic acid (AsA; 0.2 g/L) was used as a reference solution, while distilled water was used as control.
