Metabolites in the fruits of edible plants include sweet sugars, visually appealing pigments, various products with human nutritional value, and biologically active plant hormones. Although quantities of these metabolites vary during fruit development and ripening because of cell division and enlargement, there are few reports describing the actual dynamics of these changes. Therefore, we appli...

Pear (Pyrus communis L.) is one of the important species fruits that are widely cultivated in Syria. Seed propagation pear an way to obtain seedlings be used as grafting assets, but method seed difficult due effect dormancy factors germination. The research was carried out during 2020 and 2021 study effects stratification for three periods (30–60–90 days) using ascorbic acid at a concentration ...

Cultured pear (Pyrus communis 1. cv Passe Crassane) cells were subjected to temperatures of 39,42, and 45°C. Heat-shock protein (hsp) synthesis was greater at 39'C than at temperatures above 40'C and continued for up to 8 h. Both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. Polysome levels decreased immediately...

The interactions between plants and pollinators are complex. Flower volatiles as special olfactory cues could influence the foraging choices of pollinators. Here, we conducted bioassays to evaluate role flower on attraction honey bees (native Apis cerana exotic mellifera) pears Pyrus bretschneideri communis). Chemical electrophysiological approaches were used determine antennal responses from p...

Cultured pear (Pyrus communis L. cv Passe Crassane) cells were subjected to temperatures of 39, 42, and 45[deg]C. Heat-shock protein (hsp) synthesis was greater at 30[deg]C than at temperatures above 40[deg]C and continued for up to 8 h. Both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. Polysome levels decrease...
