The relationship of phenolic composition and polyphenoloxidase activity (PPO, E.C. 1.14.18.1) to browning potential (BP) was studied in buffer extracts of peach [Prunuspersica L. Batsch) and nectarine [P. persica var. nectarine (L.) Batsch] fruit skin. The BP varied among cultivars with ‘Flavorcrest’ having the highest value and ‘Maycrest’ the lowest. On average, over 83% of the browning measur...

Two trials involving 20 Prunus rootstocks were conducted under greenhouse conditions to screen for resistance to root-knot nematode [Meloidogyne javanica (Treub.) Chitwood]. Many of the tested materials are interspecific hybrid rootstocks and represent new commercial peach (P. persica Batsch) and plum (Prunus sp.) releases or experimental genotypes of Spanish, French, and Italian origin. In the...

introduction: pest and disease problem with the extension of fruit orchards, becomes a serious and restricted factor for orchard growers. most of the scale insect of cold region fruit trees in iran belongto family diaspididae. one of the most important pests in the fruit orchards of chaharmahal and bakhtiari province are scale insects. hall scale, mercetaspis halli (green) (hemiptera: diaspidid...

Production costs could be substantially reduced if the height of fruit trees could be lowered enough to eliminate the need for, or reliance upon, ladders in the orchard. Recent research demonstrates that high yields can be obtained on shorter trees with appropriate management techniques, but vigor control can be a problem. In 2004, selected rows of ‘Arctic Star’ nectarine trees growing in the D...

Enzymatic peeling of ‘Fuyu’ and ‘Tone-wase’ persimmon fruit was conducted for production of fresh-cut slices, and the microbiological and physicochemical quality of enzyme-peeled fresh-cut slices was compared with that of slices manually peeled with a knife. The enzymatic peeling process involved a porous treatment of the peel, heating at 100 8C for 45 s, infusion with 3% protopectinase at 37 8...

Ceratitis capitata (Wiedemann), the Mediterranean fruit fly or medfly, is one of world's most serious threats to fresh fruits. It highly polyphagous (recorded from over 300 hosts) and capable adapting a wide range climates. This pest has spread EPPO region mainly present in southern part, damaging Citrus Prunus. In Northern Central Europe records refer interceptions short-lived adventive popula...

Trials were established at Aula Dei Experimental Station (EEAD-CSIC, Zaragoza, Spain) to assess graft compatibility between peach cultivars [Prunus persica (L.) Batsch] and new Prunus spp. rootstocks or selections. Peach cvs. Catherina and Tebana and nectarine cvs. Big Top and Summergrand were grafted on peach seedlings, plum rootstocks, almond x peach hybrids, and other interspecific rootstock...

The microbiological quality and shelf life of enzyme-peeled fresh-cut persimmon slices were evaluated during storage in a high CO2 controlled atmosphere (CA) and active modified atmosphere packaging (MAP) at 10 8C. Microbial counts of the enzymepeeled slices were lower in high CO2 atmospheres (10%, 15%, and 20%) than in air during CA storage for 6 days at 10 8C with the 20% CO2 atmosphere being...
