Abstract The objective of this work was to evaluate the effect pre-harvest spraying with aminoethoxyvinylglycine (AVG) and ethephon on fruit maturation 'Baigent' apple (Malus domestica) trees grown under black anti-hail nets. treatments were: control; 125 mg L-1 AVG, sprayed 30 days before anticipated harvest time (DBAH); 120 7 DBAH; 62.5 + AVG 20 DBAH DBAH. Fruit were harvested in commercial c...

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...

Apple (Malus×domestica Borkh) fruits are stored for long periods of time at low temperatures (1 °C) leading to the occurrence of physiological disorders. 'Superficial scald' of Granny Smith apples, an economically important ethylene-dependent disorder, was used as a model to study relationships among ethylene action, the regulation of the ROP-GAP rheostat, and maintenance of H2O2 homeostasis in...

Ethylene is the major effector of ripening in many fleshy fruits. In apples (Malus x domestica) the addition of ethylene causes a climacteric burst of respiration, an increase in aroma, and softening of the flesh. We have generated a transgenic line of 'Royal Gala' apple that produces no detectable levels of ethylene using antisense ACC OXIDASE, resulting in apples with no ethylene-induced ripe...

Apple and pear scab are foliar pathogens of apple trees. Unmanaged, yield aesthetic losses can be severe. The risk resistance associated with over-reliance on fungicides means novel pathogen management methods products increasingly required. Chitin chitosan widely recognised as induced (IR) agents that trigger plant defence responses in turn enhance resilience to ingress. A container field tria...

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. hemispherica J. & C. Presl, J. communis var. megistocarpa Fern. & St. John, J. c. var. nipponica (Maxim.) Wils., J. c. var. oblonga hort. ex Loudon and J. c. var. saxatilis Pall. were sampled and DNA fingerprinting (RAPDs, Random Amplified Polymorphic DNAs) was performed. Based on 191 RAPD bands, there was litt...

This paper investigates the effects of cuticular wax on the release of strain and on the tensile properties of enzymatically isolated cuticular membranes (CMs) taken from leaves of agave (Agave americana), bush lily (Clivia miniata), holly (Ilex aquifolium), and ivy (Hedera helix) and from fruit of apple (Malus × domestica), pear (Pyrus communis), and tomato (Lycopersicon esculentum). Biaxial s...

Development, imaginal survivorship, adult longevity and fecundity of the predatory phytoseiid mite Euseius (Amblyseius) finlandicus Oudemans reared on seven different plant pollens were determined in the laboratory. The rationale behind these experiments was to assess the nutritional value and the possible effect on development and population dynamics of the mite. Mites were kept individually o...

Apples fruit quality is mainly influenced by biotic and abiotic factors. Various possible pomological approaches are able to improve market value. Among these, techniques of bagging summer pruning have become an integral part practises in many countries, because it a safe eco-friendly technique protect fruits from multiple stresses, preserving or improving the overall quality. The consists esse...

Abstract Studies were conducted in apple, Malus domestica Borkhausen and pear, Pyrus communis L. (Rosales: Rosaceae), orchards to evaluate the attractiveness of grey halobutyl septa loaded with 1 (L2) and 10 (Mega) mg of codlemone, 8E, 10E-dodecadien-1-ol, 3 mg of pear ester, ethyl (E,Z)-2,4-decadienoate (DA2313), and 3 mg of pear ester plus 3 mg of codlemone (Combo) to adult codling moth, Cydi...
