Efecto de la fertilización con nitrógeno, fósforo y potasio, sobre el contenido foliar de carbohidratos, proteínas y pigmentos fotosintéticos en plantas de Berberidopsis corallina Hook.f.

Abstract: Un número substancial de publicaciones se relacionan con aspectos de fertilización y nutrición de especies leñosas exóticas, principalmente en Eucalyptus spp. y Pinus spp., siendo escasa la información para especies nativas. Berberidopsis corallina (Berberidopsidaceae) es una especie endémica de Chile en peligro de conservación para la cual no existe antecedentes de fertilización. El objetivo de esta investigación es contribuir con nuevos antecedentes sobre el efecto estimulador de la fertilización con nitróge… Show more

“…In general, P is found in root growth processes, so applications with fertilizers at this stage allow better expression for transplant process. An optimal N, P and K balance favors chlorophyll synthesis processes in true leaves (Latsague et al, 2014).…”

“…The results observed in A coincide with the increase in leaf N and P concentration due to treatment. The suitable supply of nutrients to the plants certainly provided the necessary requirements for specific processes of the metabolism during the development of the plants (Gattward et al, 2012;Latsague et al, 2014) that resulted in increased photosynthetic capacity and…”

“…This indicates that half of the N applied in the form of NH4 + has similar results compared to a complete application of N-NH4 + in no divided root condition (Table 4). According to Latsague et al (2014), the photosynthetic capacity of leaves is related to the N content, because an adequate supplement of N is essential in the establishment of maximum demand capacity and photosynthetic capacity; but excessive use of N causes excessive expansion of the foliar area. Jorquera-Fontena et al (2016) observed that the accumulation of photosynthetic pigments in blueberry plants is an indicator of biomass production and the nutritional status of N. According to most of the research done, the ratio of chlorophyll a and b is 3:1, which varies depending on plant growth and development, cultivar, and environmental factors (Bojovic and Stojanovic, 2005).…”
