The husbandry of South American camelids maintained under middle European conditions
(TERRA-VERLAG GMBH, 1997)The popularity of South American camelids has increased in fur-ope. As a result, veterinarians are more frequently confronted with these species. Recommendations for keeping llnmas and alpacas in middle Europe are provided. -
Changes in plasma membrane H+-ATPase activity during aeration of maize roots
(1996)Plasma membrane-enriched vesicles were isolated by density gradient centrifugation from maize roots previously submersed for 2 h with or without aeration in a 1 mmol/L CaSO4 solution, a condition which can modify the rate ... -
Effect of soil humic substances on surface redox activity of oat roots
(1995)The effect of a low molecular weight (<5kDa, LMW) and a high molecular weight (>5kDa, HMW) humic fractions on surface redox activities of oat roots was studied. Oxidation of the electron donor NADH and reduction of the ... -
Plasma Membrane H+-ATPase in Maize Roots Induced for NO3- Uptake
(1995)Plasma membrane H+-ATPase was studied in maize (Zea mays L.) roots induced for NO3- uptake. Membrane vesicles were isolated by means of Suc density gradient from roots exposed for 24 h either to 1.5 mM NO3- or 1.5 mM SO4-. ... -
Pedogenic evolution and 137Cs contents in soils of the Eastern Alps (Friuli-Venezia Giulia, Italy)
(1995)Two lithosequences were examined, starting from siliceous and calcareous parent material, respectively. The morphological and chemical soil properties allowed to evidentiate different evolutionary trends. Radioactivity ... -
Plasma Membrane H+-ATPase in Maize Roots Induced for NO3- Uptake
(1995)Plasma membrane H+-ATPase was studied in maize (Zea mays L.) roots induced for NO3- uptake. Membrane vesicles were isolated by means of Suc density gradient from roots exposed for 24 h either to 1.5 mM NO3- or 1.5 mM SO4-. ... -
Water-extractable humic substances enhance iron deficiency responses by Fe-deficient cucumber plants
(1999)The ability of Fe-deficient cucumber plants to use iron complexed to a water-extractable humic substances fraction (WEHS), was investigated. Seven-day-old Fe-deficient plants were transferred to a nutrient solution ... -
Investigation of the use of honey bees and honey bee products to assess heavy metals contamination
(1996)Experiment was carried out using 12 colonies of honey bees bred in hives located near an extraurban crossroad. We analyzed the Pb, Cd and Zn deposited on the bee's surfaces and the heavy metal accumulation in the foragers, ... -
Iron reduction in iron-stressed plants of Actinidia deliciosa genotypes: Involvement of PM Fe(III)-chelate reductase and H+-ATPase activity
(1999)Micropropagated plantlets of the Actinidia rootstock D1, resistant to lime-induced iron (Fe) deficiency, and the Actinidia deliciosa line 2084 (sel. 2084), moderately sensitive to Fe starvation, were grown in nutrient ...
