“…According to Römheld & Marschner (1981), iron deficiency caused morphological changes in the roots, such as inhibition of root elongation and an increase in the diameter of the distal root and reduces the formation of capillary roots. Similar results were obtained by Erdal et al (2008) in apple, Song Chen (2004) in grapes (Vitis labruscana), Ferrarezi et al (2007) citrus rootstocks (Swingle, Rangpur, Trifoliata and Cleopatra) Nadal et al (2012) in soybean (Glycine max) and Nadal et al (2013) in Prunus persica.…”

KEYWORDS Fe oxide nanoparticles Iron deficiency Chlorosis in vitro Citrus volkameriana ABSTRACTPresent study was undertaken to explore of the effect iron nanoparticles (uncoated iron oxide nanoparticles, iron oxide nanoparticles coated with polyethylene glycol and FeEDTA and FeEDDHA chelates) on prevention of chlorosis in Citrus volkameriana. Study was carried out under the in vitro condition on MS medium supplemented with different iron compositions. Various growth attributes such as chlorophyll a, b, iron content of leaves, root and shoot length, number and area of leaves, degree of chlorosis, dry and fresh weights of seedling, roots and shoots were measured in end of study. Results of study revealed that seedlings grown on MS culture medium supplemented with uncoated nanoparticles of iron oxide had the highest rates of iron uptake and the lowest degree of chlorosis. Further, plant cultured on the MS medium with uncoated iron nanoparticles significantly increased vegetative growth characteristics such as, fresh and dry weights and chlorophyll content over the control (MS without chelated iron). Plant cultured on MS medium supplemented with uncoated iron oxide nanoparticles showed superiority over the plant cultured on MS media without iron and improved leaves growth characteristics and decreased chlorosis.

“…Studies have found that "Volkameriana,"' and "sour orange" plants were tolerant; "Carrizo and Troyer" citranges were intermediate, whereas the "Poncirus trifoliata" rootstock was more sensitive to iron chlorosis [46,48,49,51,54]. In addition, Cimen et al [55] indicated that Young "Navelina" orange trees budded on Tuzcu 31-31 sour orange, and Gou Tou sour oranges performed best under Fe deprived conditions in plant growth chamber. Navelina on Volkameriana and Cleopatra mandarin was moderate; C-35 citrange and local trifoliate were poorly adapted to lime-induced Fe deficiency ( Figure 3).…”

Abiotic and Biotic Stress in Plants - Recent Advances and Future Perspectives

View full text Add to dashboard Cite

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.

A citricultura brasileira é uma atividade de destaque na pauta econômica do País. O seu crescimento e manutenção requerem a produção de 15-20 milhões de mudas anualmente. Em vista das características dos viveiros e das variedades porta-enxertos e copas, há a necessidade de se estabelecer um manejo nutricional adequado dessas plantas. O estudo teve o objetivo de avaliar o suprimento de N e Cu e o desenvolvimento e estado nutricional de mudas de laranjeira 'Pêra', sobre porta-enxertos de limoeiro 'Cravo' e tangerineira 'Sunki'. Foram aplicados dois níveis de N = 120 e 240 mg L-1, e quatro de Cu = 0, 5, 10 e 20 mg L-1 (Cu-EDTA) via fertirrigação, entre o transplantio de porta-enxertos e a finalização da muda. O porta-enxerto de 'Cravo' possui maior vigor comparado à 'Sunki' com base na produção de massa seca e tamanho das plantas. O maior desenvolvimento das mudas foi obtido com a solução de fertirrigação com 240 mg L-1 de N e 5 a 10 mg L-1 de Cu. Houve efeito depressivo na concentração de 20 mg L-1 de Cu, associado a teores de Cu das folhas de 20 mg kg-1 e das raízes de 50 mg kg-1. Esse prejuízo foi menor com o maior fornecimento de N. Da mesma forma, o pegamento de borbulhas da laranjeira 'Pêra' foi ótimo nas doses intermediárias de Cu. A demanda de Cu foi maior para mudas sobre 'Sunki' na maior dose de N e o excesso desse micronutriente reduziu a absorção de Mn. Os teores de Cu foram maiores nas raízes da porção superior do recipiente de produção das muda, o que coincidiu com a maior adsorção do elemento no substrato, com máximo acima de 300 mg kg-1 de Cu.
