The apple maggot fly, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), infests non-commercial apple (Malus domestica (Borkh.) Borkh.) and native black-fruited hawthorns (mostly Crataegus douglasii Lindl.) in central Washington, but little has been published on the abundance of the fly in this region. In this paper, the abundance of R. pomonella across different sites near apple-growing area...

CO, exchange rales (CO, evolution) of late-maturing cv. Cai Red peaches, exposed lo different photon flux densities, were simulated from 24 days after flowering {DAF) until harvest by using light and temperature response curves measured on attached fruits in the field at biweekly intervals. The daily patterns of dark respiration rales per unil dry weight indicated their dependence on temperatur...

The vascularization of the pedicel in Marisol clementine (Citrus clementina Hort. ex Tanaka) has been characterized in relation to fruit growth. Phloem and xylem formation occurred during the first half of the period of fruit growth. Phloem cross-sectional area reached its maximum value by the end of fruitlet abscission, 78 d after anthesis (DAA), shortly after the rate of accumulation of dry m...

bacterial canker of stone fruit trees caused by pseudomonas syringae pv. syringae has become widespread throughout most fruit growing areas of iran (abbasi et al 2013). to evaluate the diversity of the strains and possible species inciting the disease in the central areas of the country, surveys were made in 2014 and 2015 in some central provinces including charmahal-and-bakhtiary, isfahan, qum...

An increase in the land area dedicated to super-high density olive orchards has occurred in Chile in recent years. Such modern orchards have high irrigation requirements, and optimizing water use is a priority. Moreover, this region presents low water availability, which makes necessary to establish irrigation strategies to improve water productivity. An experiment was conducted during four con...

The soil and climate conditions in Romanian Northeastern area are favorable for cherry cultivation, but some times can occurred calamities. paper presents a study which during 2020 at the Research Station Fruit Growing (N-E of Romania), using five sweet genotypes as research material: ‘Van’, ‘Croma’, ‘Elaiași’, ‘HC920402’, ‘HC930208’. Observations determinations were performed regards to frostd...

BACKGROUND There is growing evidence for a relationship between fruit and vegetable consumption and all-cause mortality. Few studies, however, specifically explored consuming raw versus cooked vegetables in relation to health and mortality outcomes. The purpose of this study was to examine the relation of all-cause mortality with: a) fruit and vegetable consumption, either combined or separatel...

Citrus crops are considered to be relatively poor hosts for Queensland fruit fly, Bactrocera tryoni (Froggatt), as for other tephritid species. Australian citrus growers and crop consultants have reported observable differences in susceptibility of different citrus cultivars under commercial growing conditions. In this study we conducted laboratory tests and field surveys to determine susceptib...

Fruit water balance is determined by entry of sap through xylem and phloem, and losses due to back̄ow from fruits to other organs, and to transpiration. The latter, which may vary according to growing and climatic conditions, plays a signi®cant role in fruit water balance. To better understand and predict tomato fruit transpiration, measurements of the transpiration rate of shaded and nonshaded ...
