Abstract
The changes of the assimilation pigments content of turf Festuca spp. leaves after application of different nutrition forms
Highlights
Colour, as one of the qualitative indicators of turfs, is closely related to the concentration of green leaf dye-chlorophyll
The highest content of chlorophyll a (496.69 mg m-2) in the leaves of grasses was recorded on the treatment fertilized by turf fertilizer
The highest connect values of chlorophyll a were on turfs fertilized by inorganic fertilizers (475.62–496.69 mg m-2) and organic fertilizer 1 (492.16 mg m-2)
Summary
As one of the qualitative indicators of turfs, is closely related to the concentration of green leaf dye-chlorophyll. Carotenoids, together with chlorophyll, are part of photosynthetic organisms and form a reciprocal process (Beard, 1973; Xu et al, 1995; Kovár and Gregorová, 2009). Biosynthesis of assimilation pigments in plants is affected by variety of external and internal factors (Masarovičová et al, 2000). The color of leaves, as the main component for assessing the aesthetic quality of turfs, is often evaluated in field experiments (Karcher and Richardson, 2003; Gregorová and Kovár, 2010; Hric et al, 2016a). Nitrogen (N) is a component of chlorophyll. In the absence of nitrogen of plants change their appearance. If the nitrogen content in the leaves of plants is low, the leaves turn yellow. With a large nitrogen deficiency, the leaf dies (Hrabě et al, 2009; Aldous, 2011)
