GROWTH, MINERAL UPTAKE AND STEM ELONGATION OF LILLIUM SPP. AS A FUNCTION OF PLANT DENSITY
The economic importance of floriculture and the Lilium production as cutting flower in Mexico has increased in the last years. Little research exists related to Lilium production in closed hydroponic systems with inorganic substrates. Therefore it is considered important to develop studies about plant density, plant growth, the nutrients demand, and their effect on stalk height. The objectives of the research were: evaluate the effect of three population densities of Lilium for cutting flowers on the stalk height and, to estimate the accumulation for the dry matter and some nutrients during the plant growth. Previous reports suggest the biggest stalk height corresponded to densities of 49 and 35 plants m-2; the models for each plant height were sigmoid population density effect on total dry matter. All the mathematic models concerning accumulation of dry matter, the nitrogen, phosphorous, potassium, calcium and magnesium uptake revealed a significant adjustment (p≤0.05). In fact, floral buttons and flowers showed an excellent sanitary and aesthetic condition. Flower harvest was performed 62 days after planting the bulbs.
