MANGANESE DEFICIENCY IN PEACH TREES: PROGNOSIS AND FRUIT QUALITY

Manganese Deficiency in Peach Trees:

In previous studies was pointed out that it may be possible to detect subclinical manganese deficiencies in the field before visual symptoms have developed. In this work, by in situ fluorescence measurements, we demonstrate that it is possible to predict, at the beginning of the season, which trees will develop manganese deficiency several months later. Fo/Fm ratio of young manganese deficient ...

Preliminary Evaluation of Productivity and Fruit Quality for Seven Peach Rootstocks in Chile

Fruit productivity and quality of eight years peach and nectarine cultivars (Rich Lady, Ryan Sun, Ruby Diamond and Venus) grafted onto Cadaman-Avimag, Viking, Atlas, GxN 15, GF 677, MRS 2/5 and Nemaguard (control) rootstocks were evaluated. A Split Plot experimental design was used, with each rootstock/scion combination as an experimental unit. Total yield, fruit size distribution, number of fr...

Phenotypic diversity and relationships of fruit quality traits in peach

Quality oriented fruit breeding: Peach [Prunus persica (L.) Batsch]

Promising new tools for peach fruit quality breeding have been revised in this work. These tools included fruit quality evaluation through physical, chemical and sensorial parameters and post-harvest storage evaluation. The development of a feasible method for an early testing of peach selections generated in breeding programs is also well described together with the discussion of the inheritan...

Effects of partial ringing and heating of trunk on shoot growth and fruit quality of peach trees

Small-sized peach (Prunus persica [L.] Batsch.) trees for commercial fruit production have not been available due to the lack of suitable dwarfing rootstocks that have a wide range of compatibility among cultivars. Effects of partial girdling and trunk heating on the growth, yield, and fruit quality of peach were studied. A 4 cm wide partial ring of bark was removed at a height of 25 cm from th...
