Recipientes e substratos na germinação e desenvolvimento de crisântemo e amor-perfeito

Abstract

The aim of this work was to evaluate the substrate effect and recipient size on the germination and initial growth of chrysanthemum and perfect-love ornamental plants. The works was carried out in the Horticulture Nursery from UTFPR - Campus Dois Vizinhos - Paraná State, Brazil. The experimental design was in blocks randomized, in factorial 3 x 4 (recipient size x substrate), with four replications, considering 4 recipients by plot. It was used as recipients, small, medium and king container and as substrate the Plantmax® and the mixture Red Latosoil + Sand + Poultry Litter 1 (1:1:1 v/v), Red Latosoil + Sand + Poultry Litter 2 (1:1:1 v/v) and Red Latosoil + Sand + Poultry Litter 1 + Poultry Litter 2 (1:1:1:1 v/v). The Poultry Litter 1 and 2 had wood shavings and sawdust as different ingredients, respectively. The germination (%), total lenght plants(cm), roots length(cm), height(cm), leaf number and plants dry mass matter(g), were evaluate 63 days after experiment installation. For germination and early development of perfect-love the best container was small with a mixture the red latosoil + sand + Poultry Litter 1 + Poultry Litter 2 (1:1:1:1 v/v). For Chrysanthemum, besides to this container and mixing, the mixtures were also important Red Latosoil + sand + Poultry Litter 1 (1:1:1 v/v) e Red Latosoil + sand + Poultry Litter 2 (1:1:1 v/v).

Production and quality of three varieties of chrysanthemum grown in pots with different NPK rates

“…Higher values of stem length were observed for Calabria, with average of 19.7 cm, similar to Sheena with 18.6 cm, and higher than variety Indianapolis, with 17.2 cm. Similar results were found by Mota et al (2007) and Pirola et al (2015) whom noticed increments in plant height when increasing the dosage of the applied treatment. This is due to the fact that these nutrients are involved in cell elongation and division, and also because they are fundamental constituents of organelles and compounds involved in photosynthesis, especially nitrogen, thus resulting in response of stem length (BARBOSA et al, 1999;RODRIGUES et al, 2008;CASTRO et al, 2011;BALDOTTO and BALDOTTO, 2015).…”

“…Substrate temperature, light and fertilization are of paramount importance in quality and productivity of inflorescences (BACKES et al, 2004;PIROLA et al, 2015). The knowledge of nutritional needs of the crop has not only an important impact on quality, productivity and longevity of the inflorescences and plant but also on maximizing the ecosystem efficiency with minimum impact on environment avoiding eutrophication on rivers and lakes (MOTA et al, 2013;SCHWAB et al, 2014).…”

Produção de girassol ornamental e o uso de resíduo industrial como substrato

“…Sousa et al (2011) em produção de zínia (Zinnia elegans (Jacq)) da família das Asteraceae em diferentes recipientes atingiu as melhores médias para a altura de 6,18 cm em recipiente com menor volume, contrário aos resultados encontrados no presente estudo em que os vasos de maior tamanho alcançaram a altura de 18,13 cm se sobressaindo em relação ao menor com 16,82 cm. Em estudos realizados por Pirola et al (2015) em crisântemo (Dendranthema grandiflora (Tzvelev)), observou-se os melhores resultados para a altura da planta em cultivo com vasos maiores. É importante ressaltar que a altura das plantas obtidas no presente ensaio para os dois tipos de vasos testados, estão dentro do padrão de comercialização do Veiling Holambra (Veiling Holambra, 2018).…”

Development of Datura metel in different pot sizes

“…Different genotypes, even those with more expressive growth, can be grown in pots, with their size monitored, in order to obtain a harmony of the plant, and even a better efficiency in the production of the aerial part (Pinto et al, 2010). Pirola et al (2015) reported that countless materials can be used as a container in the development of chrysanthemum and pansy, ornamental species of great importance in the market, demonstrating that each container has a different influence on the root development of plants, consequently providing the largest total length of the plants. plants Concerning these characteristics, the development of scientific work related to pot adaptation, more efficient cultivation techniques that can guarantee lower production costs, becomes important.…”
