COMPARISION DYNAMICS OF N, P, K CONTENTS IN DIFFERENT ANTHURIUM CULTIVARS (Anthurium cultorum Birdsey) GROWN IN EXPANDED CLAY
Tomasz Kleiber | Andrzej Komosa
Vegetation experiments were conducted in the years 2002–2004, in two specialist horticultural farms. The dynamics of nitrogen, phosphorus and potassium contents were analyzed in the index parts of selected anthurium cultivars (Anthurium cultorum Birdsey): ‘Baron’, ‘Choco’, ‘Midori’, ‘Pistache’, ‘President’ and ‘Tropical’. Plants were grown in expanded clay using drip fertigation with standard nutrient solution. Fully expanded leaves after fresh-cut flowers as the index parts for chemical analyses were collected every 2 months over the period of 3 years. A varied dynamic of nutrient contents was found in the index parts of plants. During the 3 years of studies a downward trend was recorded for nitrogen content, while an upward trend was observed for contents of phosphorus and potassium. A cultivar differentiation was shown for contents of the above mentioned nutrients and quantitative proportions between them.
