A Tylenchulus sp. found in a Georgia peach orchard parasitized peach roots in the greenhouse. Citrus roots were not parasitized, indicating that the nematode was not the citrus nematode. Morphologically similar populations were found in one peach orchard in Alabama, two orchards in Arkansas, and one in South Carolina. Males were present in the Alabama populations and one of the Arkansas populat...

Penetration of second-stage juveniles (J2) of Meloidogyne incognita into tomato root explants and in vitro propagated peach plantlet roots were compared. Five inoculum levels were used: 25, 50, 75, 100, and 200 J2 for tomato; and 50, 100, 200, 500, and 1,000J2 for peach. The greatest root penetration into tomato was 30% at the 75 J2 level, but the maximum penetration into peach roots was only 8...

mended during the first season of growth. During subsequent years, summer and dormant pruning requirements are similar to the standard open-vase system grown in California. Because of the uniform and relatively simple tree structure, individual scaffolds, rather than whole trees, can be used as functional units for crop load management. The Kearney Agricultural Center Perpendicular “V” (KAC-V) ...

New foreign rootstocks for peaches [Prunus persica (L.) Batsch] are now being introduced into the United States through commercial nurseries for future sales to stone fruit growers. Almost all of these rootstocks are complex Prunus L. hybrids that are propagated vegetatively. Past experience with foreign Prunus rootstocks has shown that extensive testing is critical to avoid potential problems ...

Traveler: Adrián Ares-University of Hawaii Objectives: The objective of this trip was to discuss P diagnostics and fertilization experiments for peach palm (Bactris gasipaes) with Costa Rica collaborators and to visit peach palm plantations in order to refine the research protocols for these experiments. The overall goals of this portion of the project are: 1. To determine advantages and disadv...

Background IgE-mediated allergy to peach represents a frequent cause of severe anaphylactic reactions in Mediterranean countries. Pru p 3, a nonspecific lipid transfer protein (LTP) from peach, was identified as an important elicitor of IgEmediated food hypersensitivity reactions to peach. Specific immunotherapy is currently the only allergen-specific and disease-modifying treatment of allergie...

TCP-Peach has recently been proposed for IP network scenarios characterized by long round trip times and high bit error rates, such as satellite networks. In the TCPPeach congestion control scheme, Slow Start and Fast Recovery are replaced with new algorithms called Sudden Start and Rapid Recovery. In this paper protocol refinements for TCP-Peach are proposed to allow it to be utilized in coope...

Experiments were conducted to investigate the effects of low temperatures on anthocyanin accumulation in apple and peach shoots. The anthocyanin concentration in both the apple and peach shoots increased rapidly during cold acclimation reaching the peak value in early December. The anthocyanin might be accumulated in shoots as a result of leucoanthocyanidin conversion. When apple and peach shoo...
