Abstract
Lilium longiflorum Nellie White and Lilium hybrid Brunello plants were grown in silica sand culture to induce and photograph symptoms of nutritional disorders.
Plants were grown with a complete modified Hoaglands all nitrate solution: (macronutrients in mM) 15 NO3-N, 1.0 PO4-P, 6.0 K, 5.0 Ca, 2.0 Mg, and 2.0 SO4-S, plus M concentrations of micronutrients, 72 Fe, 18 Mn, 3 Cu, 3 Zn, 45 B, and 0.1 Mo.
The treatments causing nutrient deficiency symptoms were induced with a complete nutrient formula minus one of the nutrients.
Boron toxicity was also induced by increasing the element 10× higher than the complete nutrient formula.
Reagent grade chemicals and deionized water of 18-mega ohms purity were used to formulate treatment solutions.
The solution drained from the bottom of the pot was captured for reuse.
A complete replacement of nutrient solutions was done weekly.
Plants were monitored daily to document and photograph sequential series of symptoms as they developed.
Typical symptomology of nutrient disorders and critical tissue concentrations are presented.
Symptoms of nitrogen, sulfur, boron, and iron deficiencies and boron toxicity were the first disorders documented in lilies, and these disorders may be a more likely problem encountered by a grower.
