“…These results are in agreement with those of previous works under different field conditions where the trees on FA‐13 had smaller canopy volumes but were more productive than those on other commonly used rootstocks such as Carrizo citrange [ Citrus sinensis (L.) Osbeck × Poncirus trifoliata (L.) Raf.] or Cleopatra mandarin (Forner et al, 2003; Forner‐Giner et al, 2003). Accordingly, Lliso et al (2004) suggested that the dwarfing mechanism induced by some citrus rootstocks is mediated by enhanced reproductive development, resulting in reduced vegetative growth.…”

“…From among these, a hybrid of Cleopatra mandarin (CM) ( Citrus reshni hort. ex Tanaka) × Poncirus trifoliata (L.) Raf., specifically Forner‐Alcaide 13 (FA‐13), was selected for its characteristics, which include high productivity and good fruit quality of the scion cultivar (Forner et al, 2003; Forner‐Giner et al, 2003). Furthermore, in previous experiments under greenhouse conditions, FA‐13 showed higher net CO 2 assimilation rates than Cleopatra mandarin in the absence of stress (Forner‐Giner et al, 2009).…”

The effects of two rootstocks on tree growth, fruit set and development, yield, COj assimilation, ^^C-photoassimilates transport, and carbohydrate distribution were investigated. Cleopatra mandarin (CM) {Citrus reshni hort. ex Tanaka) and Forner-Alcaide 13 (FA-13) [Citrus reshni hort. ex Tanaka x Ponoirus trifoliata (L.) Raf.] rootstocks were used for this study. The first experiment was performed with 2-yr-old plants grown under greenhouse conditions. The results showed that leaves from navel orange [Citrus sinensis (L.) Osbeck] grafted onto FA-13 rootstock (navel onto FA-13) had higher net COj assimilation (AcOj) rates than those from navel orange grafted onto CM rootstock (navel onto CM). Also, FA-13 rootstock induced an increase in leaf transpiration rate with respect to CM rootstock resulting in similar water use efficiency (WUE) values. The higher of photosynthetic activity in navel onto FA-13 plants resulted in higher photoassimilate transport (^-'C-labeled) from leaves to roots compared to navel onto CM plants, causing higher sucrose and starch accumulation in FA-13 roots. The second experiment was performed under field conditions using 7-yr-old trees. Navel orange grafted onto FA-13, which had the highest Aco^ values, displayed higher photoassimilate transport (^^C-labeled) from leaves to developing fruits than those on CM. navel onto FA-13 leaf sucrose content decreased compared to navel onto CM and leaf concentrations of this sugar were inversely correlated with AcOj values. On the other hand, sucrose and starch concentrations in root bark appeared to be related with fruit sink strength.In conclusion, FA-13 rootstock enhances photosynthetic rate in navel orange leaves compared to CM and differences in this parameter affected growth and increased yield.

“…Otherwise, many migrants have had to rely on loans with usurious rates to get the necessary money. 10 To avoid the watch of migration officials thousands of Ecuadorians are taking advantage of the Schengen Agreement by flying to Amsterdam, where migration officials, apparently, do not scrutinize Ecuadorians as rigorously (Alou, 1999). Under the Schengen Agreement, Ecuadorians are entitled to enter any Schengen Agreement country as tourists for 90 days and travel to any other member country.…”

The Panic to Leave: Economic Crisis and the “New Emigration” from Ecuador

International Migration

Prior to the late 1990s, Ecuadorian international migration was directed primarily toward the United States. Of the estimated 400,000 Ecuadorians living in the United States, most are concentrated in metropolitan New York and many hail from the south–central highlands of Cañar and Azuay Provinces. In the mid– to late–1990s, Ecuador entered a political and economic crisis just as clandestine transportation to the United States became increasingly expensive and dangerous. Within two years Ecuadorian migration diversified radically and a “new emigration” formed. Many thousands of Ecuadorians from throughout the country migrated to Europe, mostly Spain, but also to France, Italy, and The Netherlands. Prior to 1998, few Ecuadorians lived in Europe, but now, Ecuadorians are the largest immigrant group in Madrid and one of the largest in Spain. The migrant stream was led by women and composed of people from a variety of ethnic and socioeconomic backgrounds. Ecuadorians find themselves working in a variety of services (especially women) and negotiating a volatile, even hostile, social, and political environment. This “new emigration” has numerous implications for Ecuadorian families, the economy, and the nation–state. Understanding the implications requires a comparative approach that examines at least three aspects of the new emigration: the role of gender, the importance of transnational ties and connections, and the emerging roles of state and non–state actors in the formalization of migration.

Physicochemical changes and chilling injury disorders in ‘Tango’ mandarins stored at low temperatures

et al. 2020

BACKGROUND The susceptibility to chilling injury and quality changes of ‘Tango’ mandarins stored at different temperatures was evaluated in fruit grown at two locations in Andalusia (Spain) and grafted on Carrizo Citrange or FA5 rootstock. The peel disorders were also characterized by a microstructural study. RESULTS Fruit developed chilling injuries, manifested as pitting lesions affecting the equatorial area of the fruit stored at 1 °C or 5 °C; fruit growing on FA5 rootstock showed a slightly lower incidence. The microstructural study revealed that only the upper layers of flavedo were affected in the damaged fruit, the epidermal and hypodermal tissues being dramatically collapsed. Although the fruit was prone to accumulate ethanol, especially after the shelf life that followed the different periods of cold storage, the ethanol did not compromise the overall flavor. CONCLUSIONS Storage of ‘Tango’ fruit was limited by chilling injuries when stored at 1 °C or 5 °C for more than 20 days. Moreover, at these temperatures, the fruit was prone to accumulate ethanol and develop off flavors. At 9° C, the fruit could be stored for 30 days without compromising external or internal quality. Growing location and rootstock influenced some quality attributes at harvest but not during storage. © 2020 Society of Chemical Industry
