“…The high level of bicarbonate ions in the soil affects metabolic processes in roots and leaves, decreasing soil and plant Fe availability, leading to the condition known as lime-induced iron chlorosis. The most evident effect of Fe chlorosis is a decrease in photosynthetic pigments, resulting in a relative enrichment of carotenoids over chlorophylls, and production of yellow, chlorotic leaves resulting as a decrease in fruit yield and quality [10,11,12]. Drought is considered as the principal factor that limits global agricultural production, among environmental constraints.…”

Citrus species are the most widely produced fruit crops in the world. Citrus fruits are mainly produced in coastal areas in several countries as well as Mediterranean region, and production in these regions is affected by both biotic and abiotic stresses, including drought, extreme temperature, salinity, citrus canker, citrus tristeza virus, citrus greening, and others. The use of rootstocks in fruit production includes not only stronger resistance against pathogens but also a higher tolerance to abiotic stress conditions such as salinity, heavy metals, nutrient stress, water stress, and alkalinity. There is extensive genetic diversity in citrus which provides several materials to be used as rootstocks against abiotic stress. In this work, we tried to provide an overview of the abiotic stresses in citrus by combining literature with our studies, role of citrus rootstocks commercially used against abiotic stresses and rootstock breeding in citrus.

“…Additionally, lack of Fe reduced the formation of thylakoid membranes in chloroplast (Chouliaras et al, 2004a). Physiological parameters, such as chlorophyll and CO 2 gas exchange measurements, can substantiate the tolerance of plants to Fe deficiency or high pH conditions (Cimen et al, 2014). In this study, Volkameriana, known as the tolerant rootstock to iron deficiency, was found to have higher chlorophyll and Pn values than Swingle citrumelo.…”

W. Murcott scion, budded onto two rootstocks, was evaluated under high pH conditions supplied with different Fe levels. Plant dry weight, leaf area, iron chlorosis symptom scale, leaf chlorophyll concentration, net photosynthetic rate, and ferric-chelate reductase (FCR) activity variables were investigated under high pH conditions. Control plants (T1) produced the most leaf area, whereas plants grown without Fe (T2) produced the least. Dry weight was highest in 'Volkameriana' T1 (control) plants and lowest in 'Swingle citrumelo' T3 (10 µM Fe and 7.8 pH) and T2 (0 µM Fe and 7.8 pH) treatments. Significant differences in SPAD and iron chlorosis scale reading were found between rootstocks and treatments. Treatments significantly affected the net photosynthetic rate of the W. Murcott mandarin. Moreover, it was found that tolerant rootstock had higher FCR activity in application T2 than in applications T3 and T4 (100 µM Fe and 7.8 pH). The data of the present study suggested that scion budded onto Volkameriana rootstock showed a higher tolerance to iron deficiency than those budded onto Swingle citrumelo under high pH conditions.

“…For growth parameters, the number of leaves, plant height and plant fresh weight were the most affected by the high pH treatment. Previous studies also claim that bicarbonate ions hamper the development of plant (Mengel, 1994;Sabir et al, 2010;Cimen et al, 2014). The growth responses of the genotypes to iron chlorosis were different from each other.…”

“…Under Fe deprived conditions, sour oranges maintained significantly greater Fe and chlorophyll contents compared with local trifoliate. The ability of sour orange rootstocks to maintain high leaf Fe and chlorophyll concentrations under Fe deprived conditions have been documented previously (Sudahono et al, 1994;Pestana et al, 2005;Cimen et al, 2014). Iron chlorosis scale observations were used in previous citrus studies.…”

Turkey is one of the major citrus producing countries in the Mediterranean Basin. Approximately 90% of the total citrus production in Turkey is carried out in the Mediterranean Region. Soil of the Mediterranean region is calcareous and because sour orange is tolerant to high pH, the rootstocks is widely used in this region. Sour orange rootstock, which is well adapted to calcareous soils, has positive effects on yield and quality, but is extremely sensitive to Citrus Tristeza Virus disease. Because sour orange is very sensitive to tristeza, there is a need to find an alternative rootstock that is well adapted to calcareous soils and has good fruit yield and quality. For this purpose, 16 citrus rootstock and genotypes could be used as a rootstock, were tested against high-pH conditions for iron chlorosis in growth chamber. At the end of this experiment, Tuzcu 891 sour orange, Gou Tou sour orange and Antalya Cleopatra mandarin were the most tolerant; Duncan grapefruit, Tuzcu 31-31 sour orange, Sunki mandarin, Nasnaran mandarin, Cleopatra mandarin x Swingle citrumelo hybrid, Carrizo citrange, C-35 citrange and Marumi kumquat were moderate tolerant; Volkameriana, Swingle citrumelo, Pomeroy trifoliate and Sarawak bintangor were sensitive; and a local trifoliate was found to be the most sensitive to iron chlorosis in a high pH medium.
