Fluoride increases lead concentrations in whole blood and in calcified tissues from lead-exposed rats
(ELSEVIER IRELAND LTD, 2010)
Higher blood lead (BPb) levels have been reported in children living in communities that receive fluoride-treated water. Here, we examined whether fluoride co-administered with lead increases BPb and lead concentrations ...
Dormancy, germination and emergence of Urochloa panicoides regulated by temperature
(Wiley Blackwell Publishing, Inc, 2016-02-01)
Urochloa panicoides is an annual weed of summer crops. In Argentina, in subhumid areas with monsoon rainfall, it germinates and establishes in a single flush. To (i) identify the environmental factors that modify its seed ...
Oil-producing flowers of Sisyrinchium species (Iridaceae) and their pollinators in southern South America
(Elsevier Gmbh, 2001-12)
The floral relationships existing between the mainly New World genus Sisyrinchium (Iridaceae) and oil-collecting bees were investigated in southern South America. In addition to a single species known before as producing ...
Fruit growth and chemical properties of Ribes magellanicum "parrilla"
(Elsevier Science, 2011-01)
The aim of this work was to study the time course and pattern of fruit growth and the evolution of some of the chemical attributes such as soluble solids, acidity, and anthocyanin content in Ribes magellanicum plants growing ...
Non-radiative relaxation of photoexcited chlorophylls: Theoretical and experimental study
(Nature Publishing Group, 2015-09)
Nonradiative relaxation of high-energy excited states to the lowest excited state in chlorophylls marks the first step in the process of photosynthesis. We perform ultrafast transient absorption spectroscopy measurements, ...
Toxin distribution and sphingoid base imbalances in Fusarium verticillioides-infected and fumonisin B1-watered maize seedlings
(Pergamon-Elsevier Science Ltd, 2016-05)
Fusarium verticillioides is a major maize pathogen and there are susceptible and resistant cultivars to this fungal infection. Recent studies suggest that its main mycotoxin fumonisin B1 (FB1) may be involved in ...
Compared phosphorus efficiency in soybean, sunflower and maize
(Taylor, 2009-12)
A more comprehensive understanding of the mechanisms of phosphorus (P) efficiency is agronomically significant to advance in the design of crop management schemes that increase P efficiency and reduce the need of fertilizers. ...
Comparative behavior of wheat and barley associated with field release and grain weight determination
(Elsevier, 2013-03-20)
Double-cropping using the wheat?soybean sequence is a common practice in Argentina to promote the intensification of crops within rotations. However, the late release of the fields by a delayed harvest time in wheat ...
Pericarp anatomy and hormone profiles of cypselas in dormant and non-dormant inbred sunflower lines
(Wiley, 2014-10-01)
The pericarp anatomy and the effects of storage after harvest, storage temperature and early cypsela imbibition on phytohormone profiles were studied in inbred sunflower lines B123 and B91. On day 0, germination of B123 ...
Drought effects on the early development stages of Panicum virgatum L.: Cultivar differences
(Pergamon-Elsevier Science Ltd., 2014-04)
We studied the response to moderate drought and re-watering in 55-day-old plants of the lowland cv. Kanlow and the upland cv. Greenville. Plants were grown in a growth chamber; drought treatment was applied by water ...
