Influence of controlled water supply on shoot and root development of young peach trees.
Three controlled water supply treatments were applied to 1-year-old peach trees grown in root observation boxes. The treatments were: I(0), growth medium maintained at 50% field capacity; I(1), water supplied when daily net tree stem diameter change was negative or zero for 1 day; I(3) as for I(1) except that water was applied after net daily stem diameter change was negative or zero for 3 cons...
متن کاملEffects of Phosphate Fertilizer on Young Citrus Trees on Flatwood Soils
Phosphate fertilizer experiments with nonbearing citrus trees were started at planting time in commercial groves on 5 flatwoods soils. The soils included 1) Brighton peat, 2) Sunniland, 3) Keri-Bradenton, 4) Immokalee, and 5) Immokalee-Pomello. Some of the phosphate treatments were applied only once, as broadcast applications at planting time. Other treatments were applied periodically to indiv...

15 صفحه اولManganese 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 ...
متن کاملAscorbic Acid Alleviates Water Stress in Young Peach Trees and Improves Their Performance after Rewatering
Exogenous application of biochemicals has been found to improve water stress tolerance in herbaceous crops but there are limited studies on deciduous fruit trees. The goal of this research was to study if ascorbic acid applications could improve physiological mechanisms associated with water stress tolerance in young fruit trees. Ascorbic acid was foliarly applied at a concentration of 250 ppm ...
