Frequently asked questions about chlorophyll fluorescence, the sequel
(Springer, 2017-04)
Using chlorophyll (Chl) a fluorescence many aspects of the photosynthetic apparatus can be studied, both in vitro and, noninvasively, in vivo. Complementary techniques can help to interpret changes in the Chl a fluorescence ...
Tropical lotic primary producers: Who has the most efficient photosynthesis in low-order stream ecosystems?
(2017-09-01)
Photosynthetic performance was assessed for the main groups of primary producers of low-order tropical streams, comprising macroalgae (11 taxa of Chlorophyta, Rhodophyta and Xanthophyta plus Cyanobacteria), bryophytes (2), ...
Ammonium and UV Radiation stimulate the accumulation of mycosporine like amino acids in Porphyra columbina (Rhodophyta) from Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2004-12)
The combined effects of ammonium concentration and UV radiation on the red alga Porphyra columbina (Montagne) from the Patagonian coast (Chubut, Argentina) was determined using shortterm (less than a week) experimentation. ...
Effect of glyphosate-based herbicides on the photosynthetic responses of the macrophyte Egeria densa Planch. from topical lotic ecosystemsEfeito de herbicidas à base de glifosato sobre as respostas fotossintéticas da macrófita Egeria densa Planch. de ecossistemas lóticos tropicais
(2022-01-01)
The effects of pesticide pollution on eco-physiological responses in primary producers are understudied. To partly over-come this gap, this study evaluated the effects of a glyphosate-based herbicide, Roundup® (three nominal ...
Avaliação de furanocumarinas como inibidores da fotossíntese através de ensaios de fluorescência da clorofila a
(Sociedade Brasileira de Química, 2012-01-01)
The evaluations of Chorophyll a fluorescence emitted by superior plants carry structural information and photosynthetic apparatus function. Quantitative analysis apparatus of fluorescence kinetic were measured by energy ...
Extra-plastidial degradation of chlorophyll and photosystem I in tobacco leaves involving "Senescence-associated- vacuoles"
(Wiley Blackwell Publishing, Inc, 2019-04-15)
Chlorophyll (Chl) loss is the main visible symptom of senescence in leaves. The initial steps of Chl degradation operate within the chloroplast, but the observation that ‘senescence-associated vacuoles’ (SAVs) contain Chl ...
Variabilidade temporal e meridional de estimativas de Satélite da concentração de clorofila superficial na plataforma continental brasileira
(2010-10-01)
Forecast of biological consequences of climate changes depend on both long-term observations and the establishment of carbon budgets within pelagic ecosystems, including the assessment of biomasses and activities of all ...
