Storage of foliar-absorbed nitrogen and remobilization for spring growth in young nectarine (Prunus persica var. nectarina) trees

Contribution of vegetative storage proteins to seasonal nitrogen variations in the young shoots of peach trees (Prunus persica L. Batsch).

Qualitative and quantitative variations in the level of two low molecular weight vegetative storage proteins (VSP 19 kDa and 16.5 kDa) in peach shoots were compared with annual variations in total nitrogen and total soluble proteins. Protein patterns were obtained by SDS-PAGE and silver staining on each of the 12 kinetic samples collected between October 1995 and November 1996. VSP 16.5 kDa and...

Summary Soil nitrogen can alter storage and remobilization of carbon and nitrogen in forest trees

of carbon and nitrogen in forest trees and affect growth responses to elevated carbon dioxide concentration ([CO2]). We investigated these effects in oak saplings (Quercus robur L.) exposed for two years to ambient or twice ambient [CO2] in combination with low(LN, 0.6 mmol N l) or high-nitrogen (HN, 6.1 mmol N l) fertilization. Autumn N retranslocation efficiency from senescing leaves was less...

Evaluation of Antioxidant Compounds and Total Sugar Content in a Nectarine [Prunus persica (L.) Batsch] Progeny

Epidemiological studies suggest that consumption of fruit rich in phenolic compounds is associated with health-protective effects due to their antioxidant properties. For these reasons quality evaluation has become an important issue in fruit industry and in breeding programs. Phytochemical traits such as total phenolics, flavonoids, anthocyanins, L-ascorbic acid, sugar content and relative ant...

Segregation of peach and nectarine (Prunus persica (L.) Batsch) cultivars according to their organoleptic characteristics

Cultivar segregation according to the sensory perception of their organoleptic characteristics was attempted by using trained panel data evaluated by principal component analysis of four sources per cultivar of 23 peach and 26 nectarine cultivars as a part of our program to d a p c p o 9 a ( n t b t p ©
