Characterization of mechanically activated ZnO powders by raman, luminescence and IR Spectroscopy
(AIP Conference Proceedings, 2007)
Commercial zinc oxide powder was mechanically treated by grinding in a high-energy vibro-mill in a continual regime in air up to 300 minutes. Original and modified ZnO samples were characterized by Raman, photoluminescence ...
Insulin-like growth factor immunoreactivity in rat cerebellum after acute and repeated unilateral brain injury
(Elsevier, Amsterdam, 2005)
Nitrate does not result in iron inactivation in the apoplast of sunflower leaves
(Amer Soc Plant Biologists, Rockville, 2003)
It has been hypothesized that nitrate (NO3-) nutrition might induce iron (Fe) deficiency chlorosis by inactivation of Fe in the leaf apoplast (H.U. Kosegarten, B. Hoffmann, K. Mengel [1999] Plant Physiol 121: 1069-1079). ...
Somatic embryogenesis in Chenopodium rubrum and Chenopodium murale in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2005)
In order to establish an efficient system for in vitro plant regeneration of a short day plant Chenopodium rubrum L. and a long day plant Chenopodium murale L., optimum culture conditions for somatic embryogenesis were ...
The effects of growth regulators on flowering of Chenopodium murale plants in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2000)
In vitro culture of Chenopodium murale L. (ecotype 197) green and herbicide SAN 9789 - treated "white" plants was established and the effects of benzylaminopurine (BAP), indole-3-acetic acid (IAA) and gibberellic acid ...
Effect of darkness on growth and flowering of Chenopodium rubrum and C. murale plants in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2003)
Chenopodium rubrum, a short-day plant, and C. murale, a long-day plant, were grown in vitro in continuous darkness. Control C. rubrum plants exposed to continuous darkness for 15 d at cotyledonary phase, did not flower, ...
Changes in Chenopodium rubrum seeds with aging
(New York Acad Sciences, New York, 2005)
We studied antioxidative system, germination, growth, and flowering in vitro in Chenopodium rubrum seeds of different ages. Peroxidase, superoxide dismutase, and catalase activity, as well as glutathione status, were ...
Alternative respiration of fungus Phycomyces blakesleeanus
(Springer, Dordrecht, 2009)
Respiratory characteristics of germinating spores, developing mycelium and mitochondria of the fungus Phycomyces blakesleeanus were investigated by means of oxygen Clark-type electrode. The effects of respiratory inhibitors ...
The effects of photoperiod, glucose and gibberellic acid on growth in vitro and flowering of Chenopodium murale
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2000)
In vitro culture of long-day plant Chenopodium murale L was established. The effects of photoperiod, glucose and gibberellic acid (GA(3)) on flowering and growth in vitro were investigated. Oscillatory changes of photoperiodic ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Elsevier Science Sa, Lausanne, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
