BACKGROUND Qualitative and quantitative analyses of 'Zonouz' and 'Gala' apples phenolic compounds were accomplished by HPLC. MATERIAL AND METHODS Samples for phenolics study were taken at three different growing stages [1 - fruit early growing stage 2 - mid-stage of fruit development (80 days after full bloom) 3 - during commercial harvest time]. RESULTS The results showed qualitative diffe...

ABSTRACT The induction of disease-suppressive soils in response to specific cropping sequences has been demonstrated for numerous plant-pathogen systems. The role of host genotype in elicitation of the essential transformations in soil microbial community structure that lead to disease suppression has not been fully recognized. Apple orchard soils were planted with three successive 28-day cycle...

this study was conducted to evaluate the quality of the red flesh apples and golab cultivars. two iranian red flesh apples from shahroud and four golab cultivars as well as ‘gala’ as control from damavand were selected in summer 2012. fruit physical characteristics including length, diameter, fresh weight and dry weight, firmness, color and their parameters were evaluated for each cultivar. the...

Polyphenols are antioxidant ingredients in apples and are related to human health because of their free radical scavenging activities. The polyphenolic profiles of old and new apple cultivars (n = 15) were analysed using high-performance liquid chromatography (HPLC) with diode array detection (DAD). The in vitro antioxidant capacity was determined by total phenolic content (TPC) assay, hydrophi...

Fruit trees have a long juvenile phase. For example, the juvenile phase of apple (Malus × domestica) generally lasts for 5-12 years and is a serious constraint for genetic analysis and for creating new apple cultivars through cross-breeding. If modification of the genes involved in the transition from the juvenile phase to the adult phase can enable apple to complete its life cycle within 1 yea...

Because most regions of Japan are in the temperate climate zone, many deciduous and evergreen fruit crops are cultivated in Japan. In addition to fruit cultivation in the temperate zone, some southern areas, such as the Ryukyu Islands that stretch from Kyushu to Taiwan, are at the northern limits for tropical fruit production without the need of artificial heating. At present, annual fruit prod...

An attempt has been made to assess the UV-B-protective capacity of phenolic compounds accumulated in superficial structures of plants using apple fruit as a model. Two apple (Malus domestica Borkh.) cultivars (Braeburn and Granny Smith) differing in response to high fluxes of solar radiation were selected and exposed to increasing doses of UV-B radiation. The extent of UV-B-induced damage to ph...
