an increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. information on this subject is limited at the present time. in search of superior nectarines, a trial was conducted to study growing degree days (gdd), ful...

M. PLUM Mathematisches Institut I, Universität Karlsruhe, Kaiserstrasse 12, D-76128 Karlsruhe, Germany [Received on 10 December 2002; revised on 12 January 2004] It is well known that routine methods of computing the spectrum of a self-adjoint operator often lead to spurious eigenvalues in a gap between two parts of the essential spectrum. We provide a geometrical explanation for a numerical me...

Plums are one of the commercially important stone fruits that available on market in both fresh and processed form most sought-after products prunes, cans, jams, juices. Maturity, harvest, post-harvest technologies fundamentally determine relatively short shelf life plums which is often threatened by Monilinia spp. Causing brown rot worldwide. The aim present research was to use advanced analyt...

Although water is crucial to the performance of preemergence herbicides, pesticide performance has rarely been related to irrigation management. This 2-yr study investigated the effect that amount of irrigation water applied had on activity of simazine. Three rates of simazine at 0, 1.12, and 2.24 kg/ha were applied to a 3-yr-old nectarine orchard that was irrigated with microsprinklers. The pe...

The composition of lipopolysaccharide (LPS) extracted with aqueous phenol from a virulent English plum isolate of Pseudomonas syringae pv. morsprunorum varied according to the partial pressure of oxygen (pO2) in the culture medium at the time of harvest. When pO2 was low, the organism grew slowly and produced smooth LPS bearing rhamnan sidechains. As pO2 was raised, the rate of growth increased...

The potential of using compact discs as high throughput screening platforms for DNA microarraying is discussed and applied to discriminate genetic variations of Plum pox virus.
