this study was carried out to examine the effects of kaolin spray for reducing the adverse effects of high radiation and temperature, especially on fruit sunburn in apple. treatments were four concentration of kaolin (0, 2, 4, and 6%) and two important and commercial apple cultivars in fars province; ‘golden delicious’ and ‘starking delicious’. trees physiological parameters, fruit sunburn and ...

‘Pink Lady’ apple fruit were evaluated for anti-oxidative stress at various stages of fruit maturity and ripening. Fruit were harvested at weekly intervals starting 7 days before anticipated commercial harvest up to 42 days after commercial harvest (DACH), and then fruit harvested at commercial maturity were allowed to ripen at 22 ± 0.5C for 20 days. Ethylene production and respiration rate inc...

MdMYB10 gene expression results in accumulation of anthocyanin in many tissues including flesh of applefruit. The MdMYB1 and MdMYBA genes are close homologues to MdMYB10 gene and both are responsiblefor red color phenotype in apple fruit skin. In the current study, an apple genome sequence draft analysisindicated that these three genes are located in a unique contig. Further a...

Wherever the garden of Eden may have been located, most people believe that the development of the modern apple is the result of hybridisations through the centuries of cultivation with wild species growing in Europe and elsewhere. But work carried out at the University of Oxford suggests an entirely different provenance for the apple: a remote and remarkable valley region on the borders of Kaz...

Fruit softening in apple (Malus x domestica) is associated with an increase in the ripening hormone ethylene. Here, we show that in cv Royal Gala apples that have the ethylene biosynthetic gene ACC OXIDASE1 suppressed, a cold treatment preconditions the apples to soften independently of added ethylene. When a cold treatment is followed by an ethylene treatment, a more rapid softening occurs tha...

Influence of Summer Pruning Time on Shoot Growth and Fruit Quality ‘Fuji’/M.9 Apple Tree Damaged by the Low Air Temperature at Flowering Period-Apple valsa canker,Fruit weight,Light penetration,Regrowth shoot,Return bloom

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...
