Correlações canônicas entre variáveis de semente, plântula, planta e produção de grãos em mamoneira

Abstract: O objetivo deste trabalho foi identificar as relações lineares entre as variáveis dos grupos: semente, plântula, planta adulta e produção de grãos, em dois híbridos de mamoneira. O experimento foi conduzido no ano agrícola 2007/08, na Universidade Federal de Santa Maria, com três parcelas do híbrido Sara e três do Lyra. Cada parcela, com área de 240m² (15m de comprimento x 16m de largura), foi constituída por 13 fileiras. Anterior à instalação do experimento, foram realizadas avaliações das variáveis físicas d… Show more

“…In order to observe these traits, scientists can measure the plants in different phenological stages of the crop to obtain the best relationship between groups of characters (BRUM et al, 2011). Therefore, Pearson's (r) linear correlation coefficient can be used to study the relationship between two random variables, expressing the meaning and t the relationship strentgh between them (FERREIRA, 2009).…”

“…Regardless of the level of fertilization, accelerated aging was the only unaffected variable in set 3. Brum et al (2011) verified significant canonical correlations between seed morphological and seedling variables of castorbean (Ricinus communis L.); however, the authors did not study these correlations in response to fertilization.…”

“…Several studies have been developed to quantify and characterize Passiflora genetic diversity, mainly seeking to identify superior genotypes (Viana et al, 2006;Gonçalves et al, 2007;Araújo et al, 2008;Silva et al, 2009;Krause et al, 2012;Paiva et al, 2014). Plant morphological and production variables are commonly used for this purpose; however, the variables related to seed morphological and physiological quality (germination and vigor) are not commonly employed (Brum et al, 2011).…”
