Evaluation of citrus rootstocks for the high pH, calcareous soils of South Texas

Euphytica, 2008
Citrus tristeza virus (CTV) is one of the most devastating disease in areas where sweet orange or grapefruit are budded onto sour orange rootstock. In Texas, the citrus industry is located in the far south of the state in a high pH and calcareous soils region, which makes sour orange the best rootstock option. The Texas industry has been under a threat

Effects of copper rates and soil ph on growth and nutrient uptake by citrus seedlings

Journal of Plant Nutrition, 1999
Abstract Soil properties, primarily pH and organic matter, influence phytotoxicity of copper (Cu). A pot experiment was conducted to evaluate the effects of copper additions (0, 25, 50, 100, 200, and 400 mg kg−1) to three different soils [Myakka fine sand (pH 5.7), Candler fine sand (pH 6.5), and Oldsmar fine sand (pH 8.2)] on growth, and uptake of ...

RELATION OF COPPER EXTRACTABLE FROM SOIL AND pH TO COPPER CONTENT AND GROWTH OF TWO CITRUS ROOTSTOCKS1

Soil Science, 1996
The effects of 5 rates of Cu (0-200 mg/kg) amendment to a Candler fine sand (Typic Quartzipsamment) on root and shoot growth and concentrations of Cu in the respective plant parts of Cleopatra mandarin (CM) and Swingle citrumelo (SC) rootstock seedlings were evaluated at 3 pH levels ranging from pH 5 to 7.

Performance of Sidi aissa clementine on ten citrus rootstocks in a high PH calcareous soil in Morocco [PDF]

open access: possible, 2016
Sour orange is the most common rootstock used in Moroccan citruculture due to its resistance to gummosis and its high adaptability to a wide range of soil conditions. However, this rootstock was shown to have some serious problems such as susceptibility in citrus tristeza virus.

Changes in pH of a Florida citrus soil in response to basic slag and calcium hydroxide applications

1995
In a study of the effect of soil pH on a citrus decline of unknown cause (citrus blight), the pH of an acid soil was raised to 8.0. The Pomello (sandy, siliceous, hyperthermic Arenic Haplohumods) soil, modified by dredging and filling, had an original pH (1:1 soil:water) of 5.8–6.2 in the top 30 cm, a C.E.C.

Applications which decrease soil ph on yield and fruit properties in Citrus sinensis L. (cv. valencia) grown in lime-alkaline soil

2015
A raştırmada, Valensiya portakal çeşidinin yetiştirildiği alkali toprakta, toprak pH’sının düşürülmesi amacıyla 2003-2005 döneminde kükürt ve amonyum sülfat uygulamaları yapılmıştır. Bu uygulamaların toprakta pH değişimi, bitki gelişimi ve meyve verim ve özelliklerine etkileri incelenmiştir.

Effects of the sulphur, gypsum and ammonium sulphate applications on the Soil pH, vegetative growth and fruit features in Citrus limon L. (cv. Interdonat)

2015
Bu araştırmada, İnterdonat limon çeşidinin yetiştirildiği alkali toprakta pH’nın düşürülmesi amacıyla 2003-2004 döneminde kükürt, jips ve amonyum sülfat uygulamaları yapılmıştır. Bu uygulamaların toprakta pH değişimi, bitki gelişimi ve meyve kalitesine etkileri incelenmiştir.
