“…The juice content per unit weight was higher for trees on Swingle citrumelo and lower for those on C. volkameriana. These results are in agreement with those of previous work, in which the fruits with the highest TSS (Economides and Gregoriou, 1993;McCollum et al, 2002), and the lowest TSS contents were from trees on Volkameriana (Fallahi and Rodney, 1992;Stuchi et al, 2002;Ramin and Alirezanezhad, 2005;Emmanouilidou and Kyriacou, 2017). Variations in juice content due to rootstocks have also been reported in citrus (Economides and Gregoriou, 1993;Sharma et al, 2016).…”

Citrus is a conventionally produced fruit crop in extensive agricultural areas in Mediterraneantype agroecosystems. The use of rootstocks for citrus fruits is necessary for profitable production under some limiting factors, such as climactic factors, bad soil conditions, and diseases. In addition, the use of the citrus rootstocks provides a large number of choices to growers to increase fruit quality and yield, obtain early fruiting, uniform cropping and high-density planting, avoid juvenility, and control tree size. The aim of the present study was to evaluate the effects of several citrus rootstocks on the fruit yield, quality, physiological changes in leaves and leaf mineral composition of Rio Red grapefruit. Thus, seasonal changes in the leaf chlorophyll concentration, PSII efficiency (Fv / Fm), stomatal conductance (g S ), leaf temperature, leaf mineral nutrient, fruit yield and fruit quality traits of the Rio Red grapefruit variety grafted onto six commonly used rootstocks (Carrizo citrange, citremon, sour orange, Swingle citrumelo, Troyer citrange and Volkameriana) in citriculture were evaluated. The physiological responses of fully expanded young leaves to rootstocks were significantly affected by seasonal changes. Two-way ANOVA indicated significant main effects of rootstock and season and their interaction (p ≤ 0.05) on the leaf Chl concentration. Leaf Chl concentrations were lowest in April for all rootstocks. The PSII efficiency slightly decreased in the leaves of Rio Red grafted onto Volkameriana in February. The rootstocks significantly affected seasonal changes in the leaf stomatal conductance. The highest g S was recorded in October in the leaves of a Rio Red variety grafted onto the Volkameriana rootstock. Significant rootstock effects on leaf Ca, Mg, Mn, Zn and Cu concentrations were observed in the Rio Red variety. The highest leaf Zn concentration (ppm) was recorded in plants on Volkameriana, whereas the lowest Zn concentrations were recorded in plants on Troyer citrange. There were no significant rootstock effects on leaf N, P, K and Fe concentrations. The rootstocks significantly affected the fruit yield of the Rio Red variety in the 2013 and 2014 harvest years. The highest fruit yield was observed in Rio Red grafted onto Carrizo citrange in 2013, whereas it was highest in plants on Troyer citrange in 2014. The fruit weight (g), fruit diameter (mm), total soluble solids (%), juice content (%) and juice color (hue o ) of Rio Red grapefruit were significantly affected by the rootstocks.

“…No Brasil, os pomelos têm sido mais cultivados no Estado de São Paulo, que responde, praticamente, pela totalidade da produção comercial brasileira (Stuchi et al, 2003). Considerando, no entanto, que a região do vale do Rio Moxotó, em Ibimirim -Pernambuco, assim como boa parte do trópico semi-árido, reúne condições climáticas favoráveis ao cultivo desses cítricos, foram avaliados, neste trabalho, o comportamento produtivo e a qualidade dos frutos das variedades tradicionais, como também os pomelos pigmentados, de exploração comercial mais recente.…”

O uso da irrigação nas regiões semi-áridas do Nordeste brasileiro tem viabilizado o cultivo comercial de inúmeras fruteiras, tais como a uva, a manga, a goiaba, o coco e a banana. Outras espécies, como o pomelo, ou grapefruit, vêm sendo ainda objeto de estudos e avaliações. Uma coleção formada de 06 variedades de pomelos (Citrus paradisi), de polpas com coloração rosa-avermelhada ('Marsh Foster', 'Star Ruby', 'Rio Red' e 'Red Blush') e amarelada ('Triumph' e 'Marsh Foster Nucelar'), foi implantada em 1993 na Estação Experimental de Ibimirim, localizada no município de Ibimirim, no Vale do Rio Moxotó - região semi-árida de Pernambuco. Contando com cinco plantas por parcela, a coleção foi conduzida sob irrigação localizada e as avaliações realizadas durante três anos (2000 a 2002). Os resultados demostraram alta variabilidade na produção de frutos, tendo a variedade 'Marsh Foster Nucelar' alcançado a produção média de 135,0 kg/planta, enquanto a 'Star Ruby' atingiu apenas 31,0 kg/planta. O peso médio dos frutos variou de 285,5g ('Red Blush') até um máximo de 401,6g na variedade 'Triumph'. O volume de suco extraído, os sólidos solúveis totais (SST), a acidez total titulável (ATT) e a relação SSS/ATT também apresentaram mudanças entre as variedades estudadas.
