Relationship Between Fruit Development and Physiological Drop of Peach Fruit.

Role of polyamines in peach fruit development and storage.

To investigate the role of polyamines in pre- and post-harvest fruit development of 'Akatsuki' peach (Prunus persica (L.) Batsch.) we measured polyamine concentrations, activities of polyamine biosynthetic enzymes and expression of genes encoding these enzymes. Concentrations of the free polyamines, putrescine (Put), spermidine (Spd) and spermine (Spm) in pre-harvest fruit peaked 16 days after ...

Physiological Disorders in Tomato Fruit Development

Physiological disorders are abnormalities in fruit color or appearance that are abiotic in origin. These abnormalities are often confused with damage from pathogens or insects (biotic damage). Physiological disorders are distinguished from deficiencies of a single nutrient, and physical, chemical or herbicide injury. Causes of physiological disorders include genetic susceptibility, environmenta...

Hyperspectral Scattering for assessing Peach Fruit Firmness

Light scattering is related to the structural characteristics of fruit and hence is potentially useful for estimating fruit firmness. This research investigated hyperspectral scattering as a means for measuring peach fruit firmness. A hyperspectral imaging system was used to simultaneously acquire 153 spectral scattering profiles, generated by a broadband light beam, from ‘Red Haven’ and ‘Coral...

Influence of branch autonomy on fruit, scaffold, trunk and root growth during stage III of peach fruit development.

We studied the influence of branch autonomy on the growth of reproductive and vegetative organs by establishing different patterns of fruit distribution within and between large branch units (scaffolds) in mature peach trees (Prunus persica (L.) Batsch cv. 'Elegant Lady'). Different patterns of fruit distribution were established by defruiting either whole scaffolds (uneven fruit distribution b...
