fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...
Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth d...
OBJECTIVES To determine whether proton magnetic resonance spectroscopy (MRS), a newer radiographic technology, would be useful in the evaluation of the thalamus of patients in vegetative states resulting from traumatic brain injury. METHODS 14 victims of severe traumatic brain injury who were in the vegetative state and whose magnetic resonance images of the thalamus were normal underwent bil...

Vegetative propagule pressure may affect the establishment and structure of aquatic plant communities that are commonly dominated by plants capable of clonal growth. We experimentally constructed aquatic communities consisting of four submerged macrophytes (Hydrilla verticillata, Ceratophyllum demersum, Elodea nuttallii and Myriophyllum spicatum) with three levels of vegetative propagule pressu...
Plant architecture is commonly defined by the adjacency of organs within the structure and their properties. Few studies consider the effect of endogenous temporal factors, namely phenological factors, on the establishment of plant architecture. This study hypothesized that, in addition to the effect of environmental factors, the observed plant architecture results from both endogenous structur...
Postembryonic shoot development in maize (Zea mays L.) is divided into a juvenile vegetative phase, an adult vegetative phase, and a reproductive phase that differ in the expression of many morphological traits. A reduction in the endogenous levels of bioactive gibberellins (GAs) conditioned by any one of the dwarf1, dwarf3, dwarf5, or anther ear1 mutations in maize delays the transition from j...
www.frontiersin.org encountered in the vegetative state makes it utterly difficult to identify possible REM sleep other than by the presence of muscular atonia and eye movements – note that nocturnal penile erections have been convincingly shown in vegetative patients (Cologan et al., in press). The brain’s metabolic activity in a coma, as measured by fluorodeoxyglucose positron emission tomogr...
The purine nucleoside phosphorylases (PN-phosphorylase) from spores and vegetative cells of Bacillus cereus were each purified to electrophoretic homogeneity. The turnover numbers for the spore and vegetative cell enzymes were 145 and 181 moles of inosine cleaved per mole of enzyme per set, respectively. The PN-phosphorylase from vegetative cells was more anionic than that from the spores durin...
Polysomes were isolated from an enterotoxigenic strain of Clostridium perfringens during vegetative growth and at 1-h intervals after transfer into Duncan-Strong sporulation medium. During vegetative growth, about 67% of the ribosomes were in polysomal complexes. This proportion decreased to about 20% during the first 2 h in sporulation medium and then gradually increased to a maximum of 45% at...
