Air volume measurement of 'Braeburn' apple fruit.
The radial disposition of air in the flesh of fruit of Malus domestica Borkh., cv 'Braeburn' was investigated using a gravimetric technique based on Archimedes' principle. Intercellular air volume was measured by weighing a small tissue sample under water before and after vacuum infiltration to remove the air. In a separate procedure, the volume of the same sample was measured by recording the ...
متن کاملGenetic control of biennial bearing in apple
Although flowering in mature fruit trees is recurrent, floral induction can be strongly inhibited by concurrent fruiting, leading to a pattern of irregular fruiting across consecutive years referred to as biennial bearing. The genetic determinants of biennial bearing in apple were investigated using the 114 flowering individuals from an F(1) population of 122 genotypes, from a 'Starkrimson' (st...
متن کاملOccurrence of gibberellin a(3) in parthenocarpic apple fruit.
The gibberellins 'have ibeen established as effective fruit setting agents (5). In the apple, where auxins are generallly inactive, the gi'bberellins induce parthenocarpy and sustain fruit growth to maturity (2,6, 10). This pronounced fruit-setting activity and the estafblished observation that asymmetric growtth of apple fruit is related to incomplete seed development, -has encouraged investig...
متن کاملPollen density on the stigma affects endogenous gibberellin metabolism, seed and fruit set, and fruit quality in Pyrus pyrifolia
To clarify the relationship between pollen density and gametophytic competition in Pyrus pyrifolia, gametophytic performance, gibberellin metabolism, fruit set, and fruit quality were investigated by modifying P. pyrifolia pollen grain number and density with Lycopodium spores. Higher levels of pollen density improved seed viability, fruit set, and fruit quality. Treatments with the highest pol...
متن کاملInfluence of oxyfluorfen on soil micro flora in the fruit-bearing apple plantation
Studies were conducted in the period 2009-2011 in the experimental field of the Institute of Land Reclamation and Agricultural Mechanization – Sofia. The following treatments were used: a1 no herbicides with weeds (C0); a2 herbicide oxyfluorfen (Goal 2 E) at a rate of 250 ml / da; a3 herbicide oxyfluorfen (Goal 2 E) at a rate of 500 ml / da. The experiment was set up using long plots, three ver...
