TEMPORAL VARIATION AND SPATIAL DISTRIBUTION OF RELATIVE INDICES OF LEAF CHLOROPHYLL IN GRAPEVINE cv. CHARDONNAY
(Soc Brasil Engenharia Agricola, 2019-09-01)
Variation in the spatial distribution of leaf chlorophyll content associated with the progression of the phenological cycle of crops may occur in cultivated areas as a result of the variability of environmental conditions ...
WATER STRESS EFFECTS ON CHLOROPHYLL FLUORESCENCE AND CHLOROPHYLL CONTENT IN SUGARCANE CULTIVARS WITH CONTRASTING TOLERANCE
(Univ Federal Uberlandia, 2018-01-01)
One way to minimize the impacts caused by water deficit (WD) in agriculture is the use of tolerant cultivars. The physiological evaluation of plants through the potential quantum efficiency of photosystem II (Fv/Fm) and ...
Physiological, biochemical, and ultrastructural characterization of selenium toxicity in cowpea plants
(2018-06-01)
Selenium (Se) is considered a beneficial element for plants; however, in high concentrations, it causes negative effects on plant physiology and development. This study reports the first physiological, nutritional, and ...
Photosynthetic efficiency and rate of CO2 assimilation by Arthrospira (Spirulina) platensis continuously cultivated in a tubular photobioreactor
(WILEY-BLACKWELLHOBOKEN, 2012)
Similar to other photosynthetic microorganisms, the cyanobacterium Arthrospira platensis can be used to produce pigments, single cell proteins, fatty acids (which can be used for bioenergy), food and feed supplements, and ...
The effects of aluminium on the photosynthetic apparatus of two rice cultivars
(Experimental Agriculture, 2019)
Pigments from UV-resistant Antarctic bacteria as photosensitizers in Dye Sensitized Solar Cells
(2016)
Here we report the use of pigments produced by UV-resistant Antarctic bacteria as photosensitizers in Dye Sensitized Solar Cells (DSSCs). Pigments were obtained from red and yellow colored psychrotolerant bacteria isolated ...
Gas exchange, photosynthetic pigments, and growth in tomato: Lettuce intercropping
(2017-01-01)
The intercropping system is characterized by interspecific competition and leads to one of the most limiting abiotic factors for high plant yield in this cropping system. Plants under low light can carry significant weight ...
Leaf phenology and morphofunctional variation in Myrcia amazonica DC. (Myrtaceae) in gallery forest and campo rupestre'' vegetation in the Chapada Diamantina, Brazil
(Soc Botanica Sao Paulo, 2017-06-01)
Myrcia amazonica DC. occurs in gallery forest and campo rupestre'' vegetation in the Chapada Diamantina, Bahia State, Brazil-habitats with contrasting irradiance and humidity conditions. We evaluated variations in aspects ...
Effects of N supply on the accumulation of photosynthetic pigments and photoprotectors in Gracilaria tenuistipitata (Rhodophyta) cultured under UV radiation
(SPRINGER, 2011)
We have studied the effects of nitrate supply under photosynthetic active radiation (PAR) plus ultraviolet radiation (UVR) exposure on photosynthetic pigments (chlorophyll a and carotenoids), photoprotective UV screen ...
Respostas fisiológicas de cultivares de cana-de-açúcar submetidas à deficiência hídrica e a reidratação
