| elimination of ppv and pnrsv through thermotherapy and meristem-tip culture in nectarine. | the plum pox virus (ppv) and prunus necrotic ringspot virus (pnrsv) cause serious disease problems in stone-fruit trees. in this work, the possibility of obtaining plant material free from these viruses through thermotherapy and meristem-tip culture from infected nectarine shoots (prunus persica var. nectarina max, cv. 'arm king') was studied. in addition, the detection of these viruses in in vitro cultures and young acclimatized plantlets with double antibody sandwich-enzyme-linked immunosorben ... | 2003 | 12898177 |
| attraction of phlebotomus papatasi to common fruit in the field. | sand flies have been reported feeding on various plant organs including stems, leaves, and flowers but the attraction of sand flies to sugar-rich fruits has received little attention. in this study, we tested 24 commercially available fruits for their attractiveness to sand flies, and found that the top three attractive fruits were nectarine (prunus persica var. nectarina), cactus fruit, (opuntia ficus-indica), and guava (psidium guajava). these fruits were fed upon equally by both males and fem ... | 2011 | 21366776 |
| authenticity assessment of gamma- and delta-decalactone from prunus fruits by gas chromatography combustion/pyrolysis isotope ratio mass spectrometry (gc-c/p-irms). | authenticity assessment of gamma-decalactone (1) and delta-decalactone (2) from peach (prunus persica var. persica), apricot (prunus armeniaca), and nectarine (prunus persica var. nectarina) was performed using gas chromatography-isotope ratio mass spectrometry (gc-irms) in the combustion (c) and pyrolysis (p) mode. in addition, commercially available synthetic (nature-identical) 1 and 2 as well as biotechnologically produced samples (declared to be "natural") were characterized by their delta(2 ... | 2005 | 15969525 |
| storage of foliar-absorbed nitrogen and remobilization for spring growth in young nectarine (prunus persica var. nectarina) trees. | the effectiveness of spraying foliage with urea to provide nitrogen (n) to augment the seasonal internal cycling of n in young nectarine trees (prunus persica (l.) batsch var. nectarina (ait. f. maxim.), cv. stark red gold) was studied. one-year-old trees were grown with contrasting n supplies during the summer and foliage was sprayed with a 2% urea solution labeled with (15)n just before leaf senescence started. after leaf abscission had finished, the trees were repotted in sand and given no fu ... | 1998 | 12651390 |
