Nitrogen Form Regulates Aluminum Partitioning and Physiological Responses in Young Highbush Blueberry Plants Grown in Acidic Volcanic Soil

Pamela Artacho, Paulina Fernández, María Ignacia Arias, Claudia Bonomelli

Aluminum (Al) toxicity constrains plant performance in acidic volcanic soils, yet nitrogen (N) fertilization may influence Al availability and plant responses. This study evaluated the effects of N source and rate under contrasting soil liming conditions on vegetative growth, mineral nutrition, and …

Calcium Allocation to the Tree Canopy and the Edible Part of Sweet Cherry Fruit Is Hindered by Boron Soil Deficiency

Claudia Bonomelli, Gerardo Arredondo, Adriana Nario, Pamela Artacho et autres

Calcium (Ca) and Boron (B) are structural components of the cell wall with limited phloem mobility. The absorption, movement, and distribution of these two nutrients have a greater effect on leaves than on fruits since their transport is dependent on transpiration flow. …

Effects of Successive Top-Dressing Application of Lime on a Sweet Cherry Orchard in Southern Chile

Pamela Artacho, Daniel Schwantes, Pablo Martabit, Claudia Bonomelli

Annual top-dressing application of agricultural lime is a common practice in fruit orchards on acidic soils in southern Chile, which could result in surface over-liming and base imbalances. A trial was performed in a cherry orchard with an 8-year history of surface …

Aluminum Toxicity in Sweet Cherry Trees Grown in an Acidic Volcanic Soil

Claudia Bonomelli, Pamela Artacho

Chile is the world’s largest exporter of sweet cherries. New plantings have been shifted to southern regions, where aluminum (Al) phytotoxicity could be a serious constraint on establishing orchards in acidic volcanic soils. This study investigated the effects of soil Al on …

Changes in fine-root production, phenology and spatial distribution in response to N application in irrigated sweet cherry trees

Pamela Artacho, Claudia Bonomelli

Factors regulating fine-root growth are poorly understood, particularly in fruit tree species. In this context, the effects of N addition on the temporal and spatial distribution of fine-root growth and on the fine-root turnover were assessed in irrigated sweet cherry trees. The …

EFFECT OF THE SOIL TEMPERATURE ON ROOT GROWTH OF CHERRY TREES [PRUNUS AVIUM L. CV. BING/GISELA®6]: A PRELIMINARY STUDY IN CENTRAL CHILE

Claudia Bonomelli, F. Nuñez, Carlos Alberto Bonilla, Pamela Artacho

The effect of soil temperature on root growth was studied in a sweet cherry orchard [Prunus avium L. cv. Bing/Gisela®6] in Rancagua, Chile. A rhizotron was installed in the field and digital images were collected weekly from September 2008 to March 2009 …

CHEMICAL FRACTIONS OF Al IN VOLCANIC SOIL AMENDED WITH CELLULOSE WASTE

CARLOS BORQUEZ, Eduardo C. Arellano, Pamela Artacho, Claudia Bonomelli et autres

The cellulose industry generates a great volume of organic and inorganic waste, one of these wastes are called dreg (D) and grits (G).These residues have a high content of calcium carbonate, positioning them as potential bleachers in acid soils.Due to the important …

Nitrogen application to non-bearing ‘Bing’ sweet cherry trees on Gisela®6 rootstock: Effects on accumulation and partitioning of biomass and nitrogen

Claudia Bonomelli, Pamela Artacho

Newly planted sweet cherry (Prunus avium L.) orchards in Chile have mainly been established at high densities, extensively using Gisela®6 rootstock. There is no published information to establish adequate N fertilization in young non-bearing sweet cherry trees on dwarfing rootstocks, despite major …

Seasonal pattern of root growth in relation to shoot phenology and soil temperature in sweet cherry trees (Prunus avium): A preliminary study in central Chile

Claudia Bonomelli, Carlos Alberto Bonilla, Edouard J. Acuña, Pamela Artacho

The period between flowering and harvest in the sweet cherry (Prunus avium L.) is shorter than most fruit trees; thus, competition for assimilate and nutrients occurs early in the season. To properly supply water and nutrients during this critical period, optimal growth …
