Genetic study with Heliconia psittacorum and interspecific hybrids

Abstract

ABSTRACT

Configuration of watermelon fruit quality in response to rootstock‐mediated harvest maturity and postharvest storage

“…Several researchers have demonstrated the effectiveness of PCA plotting in genetic classification, evaluation of fruit quality, biodiversity and postharvest studies . This was the case in the current experiment, since PCA scores have produced useful information on fruit quality in relation to treatments.…”

Macronutrients deficiency inHeliconia psittacorumxHeliconia spathocircinata‘Golden Torch’

“…Besides that, under P-omission conditions it was verified reduction on shooting, leaf number and leaf area, when compared to plants treated with complete solution (Table 1). The inhibition of leaf expansion and shooting reduction is a direct effect of P-deficiency by the restriction on cell expansion and decreased root elongation (POTTERS et al, 2007). The reduced growth, observed in many species submitted to P deficiency, also occurs due to the reduction in cell divisions (CHIERA; THOMAS; RUFTY, 2002).…”

“…Among the more commercially cultivated genotypes, one of the most important the natural hybrid is Heliconia psittacorum x Heliconia spathocircinata Aristeguieta 'Golden Torch' (ROCHA et al, 2010).…”

Heliconia phenotypic diversity based on qualitative descriptors

“…Since the Heliconia genus was originally included in the Musaceae family (Cronquist, 1981), qualitative descriptors used in Musa spp germplasm (Silva et al, 1999) can be adapted to describe Heliconia genotypes. Some studies have been developed with the use of botanical, morphological, and agronomic descriptors of both quantitative and qualitative natures, or through the estimation of genetic parameters, which has contributed knowledge of the Heliconia germplasm (Criley, 2000;Castro et al, 2006Castro et al, , 2007Loges et al, 2007;Costa et al, 2009a,b;Rocha et al, 2010).…”
