to determine the phenolic content and antioxidant activity in some native iranian apple cultivars, some five cultivars namely: 'bekran', 'golab-e kermanshah', 'golab-e kohanz' 'golab-e sheikhi' and 'atlasi' were selected and compared with the standard cultivar 'gala'. the profiles related to four phenolic compounds (chlorogenic acid, quercetin-3-galactoside, catechin, and phloridzin) were deter...

The release of genetically engineered apple trees raises the question of their potential environmental impact, and the transfer via pollen of transgenes to cross-compatible cultivars of Malus domestica and Malus species is deemed to be the greatest source for environmental exposure. The hybrid TNR 31-35, a descendant of Malus sieversii var. sieversii f. niedzwetzkyana, carrying a homozygous, do...

An infestation of Cicadatra persica KirKaldy (Hemiptera: Cicadidae) on apple trees, Malus domestica Borkhausen (Rosales: Rosaceae), was reported for the first time in the apple fruit orchards of Erneh, Syria. Nymphs, adults, exuvia, and exit holes in the soil were observed. The species was identified as C. persica based on morphological characters. Some biological observations and an acoustic a...

Flower development in apple (Malus domestica Borkh.) extends over two consecutive seasons. During the first season, most shoot apical meristems change to reproductive growth and initiate flowers. After winter dormancy, flower development continues during the second season and ends with anthesis in the spring. To determine the beginning of the transition to reproductive growth at the molecular l...

Studies were designed to examine the effects of host plants (apple, Malus domestica Borkh., and peach, Prunus persica L.) on the development of oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae). Oriental fruit moth larvae developed faster on peach than on apple, both on fruit as well as on growing terminal shoots. On fruit, these differences were shown to cause signific...

Increasing interest in cryopreservation of dormant buds reveals the need for better understanding of the role of dormancy in cryotolerance. Dormancy stage and low-temperature survival of vegetative apple buds (Malus domestica Borkh.), cultivars 'Sampion' and 'Spartan', collected from orchard were evaluated during three seasons contrasting in temperature and precipitation throughout the arrested...

OBJECTIVE Antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. MATERIALS AND METHODS In this research the antioxidant potential of the fresh fruits of 4 cultivars (A to D) of Malus domestica (M. domestica) cultivated in the Kashan, Qamsar area was evaluated. The antioxidant activity of the samples were evaluated using two complementary antioxidant...

Plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is an important apple, Malus domestica Borkh., pest that significantly hinders sustainable apple production in eastern North America. The potential for host plant resistance to plum curculio among apple germplasm has never been rigorously evaluated. Thus, studies were conducted to assess the susceptibility of a number o...

In some areas of cultivation, a lack of salt tolerance severely affects plant productivity. Apple, Malus x domestica Borkh., is sensitive to salt, and, as a perennial woody plant the mechanism of salt stress adaption will be different from that of annual herbal model plants, such as Arabidopsis. Malus zumi is a salt tolerant apple rootstock, which survives high salinity (up to 0.6% NaCl). To ex...

Viscum album L. is a hemiparasite and most often parasitic on deciduous trees, the chemical composition of semi-parasite plant can vary depending time harvest, type host tree. The object study was leaves mistletoe growing domestic apple tree, collected in vicinity city Stavropol, common pear, territory Belorechensky district Krasnodar Territory. aim comparative content phenolic compounds antiox...
