Abstract
Nutrient uptake study is important to understand the plant nutritional requirements during its growth and to identify periods of increased nutrient demand and, thus to establish fertilization program. The objective was to determine the growth and the nutrient uptake by potted foliage anthurium. The experiment was carried out in a greenhouse and the experimental design was completely randomized with ten times of plant sampling (0; 30; 60; 90; 120; 150; 180; 240; 300; and 360 days after transplanting) and five replicates. Anthurium maricense Nadruz & Mayo seeds were germinated in polyethylene trays filled with commercial substrate and the seedlings were transplanted into plastic pots (1.16 L capacity) when reached four leaves. Plant height, leaf number and foliar area were determined every sampling. Blades with petioles, stem, inflorescence and roots were collected and dry mass and nutrients accumulation were determined. Foliage anthurium plants showed initial development but from the 180 days of planting, which corresponds with the beginning of the inflorescence emission, there was a marked increase in height, leaf area, and dry mass and nutrient accumulation. Nutrient accumulation after 360 DAT followed the decreasing order: K > Ca > N > Mg > P > S > Mn> Fe > Zn > B > Cu.
Highlights
On the one hand we have the mega diverse Brazilian flora, with a large reservoir of species with ornamental potential (CASTRO et al, 2010), and on the other hand the market of ornamental plants is avid for the introduction of novelties, and so in this context the introduction of native species in cultivation, may be a future alternative of differentiated products for Brazilian floriculture
Anthurium maricense seeds were collected from Embrapa Tropical Flowers germplasm collection and germinated in 162 cells polyethylene trays filled with commercial substrate
Foliage anthurium plant showed very slow initial growth and development, but from the 180 days of transplanting, presented a marked increase in total dry mass production, which corresponded with the beginning of the inflorescence emission; Nutrient accumulation at 360 DAT followed the decreasing order: K > Ca > N > Mg > P > S > Mn > Fe > Zn > B > Cu
Summary
On the one hand we have the mega diverse Brazilian flora, with a large reservoir of species with ornamental potential (CASTRO et al, 2010), and on the other hand the market of ornamental plants is avid for the introduction of novelties, and so in this context the introduction of native species in cultivation, may be a future alternative of differentiated products for Brazilian floriculture. Among the factors have led to increased demand, we highlight that consumers are looking for plants that are easy to maintain (easy to care) and the convenience of having a more durable product at home. It was observed by the increase in the demand for other channels of distribution of these products, like the self-service type as supermarkets (NEVES and PINTO, 2015). There are several species with great ornamental potential, conserved in public or private germplasm collections (MORAIS et al, 2017) Among these species are selections or varieties that are already ready for commercialization, others still lack some technological contribution for large-scale cultivation or propagation, and
