Changes in pigment, spectral transmission and element content of pink chicken eggshells with different pigment intensity during incubation.
Objective. The objective of this study was to investigate changes in pigment, spectral transmission and element content of chicken eggshells with different intensities of pink pigment during the incubation period. We also investigated the effects of the region (small pole, equator and large pole) and pink pigment intensity of the chicken eggshell on the percent transmission of light passing thr...
متن کاملThe effect of different concentrations of pyrene on photosynthetic pigment content and antioxidant enzymes activity in sunflower (Helianthus annuus)
World industrialization and population growth are the main reasons for the increase in environmental contamination with aromatic hydrocarbons. The presence of these compounds in the environment leads to a variety of stresses in plants and finally reduces their growth. Pyrene is one of the major toxic contaminants belonging to polycyclic aromatic hydrocarbons. Hence, in this research, the effect...
متن کاملChanges in Pigment and Element Composition of Leaves of Platanus occidentalis L. during Autumnal Leaf Senescence1
The loss of chlorophyll and total leaf nitrogen during autumnal senescence of leaves from the deciduous tree Platanus occidentalis L. was accompanied by a marked decline in the photosynthetic capacity of 02 evolution on a leaf area basis. When expressed on a chlorophyll basis, however, the capacity for lightand C02-saturated O2 evolution did not decline, but rather increased as leaf chlorophyll...
متن کاملChanges in the energy distribution between chlorophyll-protein complexes of thylakoid membranes from pea mutants with modified pigment content. I. Changes due to the modified pigment content.
The low-temperature (77 K) emission and excitation chlorophyll fluorescence spectra in thylakoid membranes isolated from pea mutants were investigated. The mutants have modified pigment content, structural organization, different surface electric properties and functions [Dobrikova et al., Photosynth. Res. 65 (2000) 165]. The emission spectra of thylakoid membranes were decomposed into bands be...
متن کاملcomparison of chemical changes during photooxidation of polypropylene film and filament containing phthalocyanine pigment
photooxidation as an important process, which significantly affects the service life of the polypropylene products, has been the subject of much theoretical and experimental study. pigments used often change the light stabilities of polypropylene. out-door applications of pigmented polypr-opylene are now increasingly developed in products such as artificial grass. the aim of this work is to exa...
