evaluation of fruit physicochemical properties and qualitative characteristics of some european pear (pyrus communis l.) genotypes
abstract considering to importance and high genetic diversity of pear (pyrus communis l.) in iran, a study was conducted on the effect of genotype on fruit physicochemical properties and qualitative characteristics of six mature european pear genotypes in teheran, iran environmental conditions. in this study some physicochemical fruit properties and qualitative characteristics such as: fruit le...
متن کاملEthylene is required for both the initiation and progression of softening in pear (Pyrus communis L.) fruit.
In order to investigate the physiological role of ethylene in the initiation and subsequent progression of softening, pear fruit were treated with propylene, an analogue of ethylene or 1-methylcyclopropene (1-MCP), a gaseous inhibitor of ethylene action at the preclimacteric or ripening stages. The propylene treatment at the pre-ripe stage stimulated ethylene production and flesh softening whil...
متن کاملModulation of antioxidant compounds in organic vs conventional fruit (peach, Prunus persica L., and pear, Pyrus communis L.).
Despite the increasing interest in organic products, knowledge about how different levels of fertilization affect nutritionally relevant components is still limited. The concentration of polyphenols and the activity of polyphenoloxidase (PPO), together with the content in ascorbic acid, citric acid, and alpha- and gamma-tocopherol, were assayed in conventional and organic peach (Prunus persica ...
متن کاملInheritance of fire blight resistance in Asian Pyrus species
Since several Asian pear species are considered to be potential source of fire blight resistance, we crossed ‘Doyenné du Comice’, the susceptible European cultivar, with four Asian pear species. The aim of the study was to establish the level of resistance of each genotype and the mode of transmission of fire blight resistance to each F1 full-sib progeny. The best sources of resistance were P. ...
متن کاملVariation of Phenolics and Antioxidant Activity between Peel and Pulp Parts of Pear (pyrus Communis L.) Fruit
The aim of present study was to appraise the antioxidant activity and phenolic contents in peel and pulp parts from two locally harvested verities of pear. The extraction yield of antioxidant components obtained with 80% methanol (80:20 methanol-water v/v) was found to be 14.30-17.50% for peel and 11.50-13.00 g/100 g for pulp on dry weight basis. The total phenolic contents and total flavoniod ...
