“…The maintenance of growth in some C. canephora genotypes may be associated with mechanisms of tolerance to low temperatures and drought, including the postponement of dehydration to maintain whole-tree photosynthesis, xanthophyll cycle efficiency, increased antioxidant enzyme activity (Fortunato et al, 2010;Silva et al, 2013), and altered leaf lipid and sugar class composition, which might differ among these C. canephora genotypes, as found in Coffea spp. Partelli et al, 2009Partelli et al, , 2011.…”

“…In addition to the large quantities of carbohydrates required during the expansion phase, the fruits of coffee trees also require substantial amounts of both potassium and nitrogen, which are reallocated from leaves and trunks to the fruit (Partelli & Marré, 2012). Indeed, decreases in the nitrogen content may impair photosynthesis, thereby contributing to the creation of excess energy in the photosynthetic apparatus , which may ultimately lead to oxidative stress and cell damage (Fortunato et al, 2010). Therefore, more than one group of plagiotropic branches should be marked for the estimation of seasonal coffee growth.…”

“…Such changes may reflect impairments or damages, but in some cases are responses towards plant cold acclimation. Such acclimation ability on coffee genotypes seems to greatly rely on the control of antioxidative conditions, frequently linked to a lower photochemical use of energy through photosynthesis, as observed to happen under low temperatures Fortunato et al, 2010), water deficit (Ramalho et al, 1998;Lima et al, 2002) and high irradiance and N-deficiency (Ramalho et al, 1998) stresses. Therefore, these changes would configure distinct morphological and physiological acclimation traits in Coffea spp.…”

Knowledge about the seasonality of different genotypes of Coffea canephora is an important tool for this crop management, particularly with regard to irrigation and fertilisation issues. This study was conducted in Espírito Santo, Brazil and aimed at to evaluate the seasonal vegetative growth in genotypes of C. canephora, as related to climatic factors, based on the growth of groups of orthotropic and plagiotropic branches with different ages. Three groups of plagiotropic branches and one group of orthotropic branches of 14 genotypes (Ipiranga and 13 that belonged to the variety Vitória) were selected and marked to followed along the one-year experiment. Three-year-old plants were cultivated under full-sun conditions, with a spacing of 3 m between rows and 1 m between plants. The growth rates of the orthotropic and plagiotropic branches differed among the genotypes and underwent seasonal variation during the entire year, with high correlations to the air temperature. Under the natural experimental conditions, the growth rate of the branches decreased when the minimum air temperatures were below 17.2ºC for most of the genotypes studied. The plagiotropic branches presented lower vegetative growth, mainly for the coffee berries, compared to the younger branches. Presumably, the genotypes of C. canephora demanded more nutrients for growth between mid-September and the second week of May.

“…Elevated levels of cryoprotectants such as sugars and proline during the CA period may play a crucial role in maintaining water potential and thus the metabolic homeostasis of the chilled cells. Chilling impairs all photosynthetic components by provoking reduction of stomatal conductance, changes in pigment complexes, and loss of photochemical efficiency (Fortunato et al, 2010). Total chlorophyll contents of lines were decreased dramatically by chilling temperature, regardless of severity, particularly in AKN 290 ( Figure 1A).…”

Two chickpea (Cicer arietinum L.) lines (AKN 87 and AKN 290) that have different chilling susceptibilities were exposed to 2 chilling temperatures (4 and 2 °C), either cold-acclimated (10 °C) or nonacclimated (25 °C), in order to understand and compare physiological and biochemical changes at the vegetative stage. Chilling temperatures resulted in reduced growth parameters, particularly in cold-acclimated lines, whereas nonacclimated plants exhibited the lowest water contents. Cold acclimation treatment led to protective changes of increased flavonoid, proline, and antioxidant enzyme activities, mostly superoxide dismutase (SOD) and ascorbate peroxidase (APX), in the lines. However, the 10 °C treatment did not significantly influence photosystem II (PSII) activity in chickpea plants. In chilling treatments, cold-acclimated plants exhibited better tolerance; of the 2 lines, AKN 87 had the higher PSII photochemical activity. The chlorophyll contents of lines decreased, while the anthocyanin and flavonoid contents of lines increased at decreasing temperatures. MDA and proline accumulation increased with the severity of the chilling stress. In conclusion, when the plants were exposed to cold acclimation, chilling induced the enhancement of antioxidant enzyme activities, particularly SOD and APX. The results demonstrated that cold acclimation reduced the deteriorative effects of chilling and provided better tolerance, specifically in AKN 87. The line AKN 87 has greater potential for cultivation as a chilling-tolerant cultivar.

“…To hybridise the two species, chromosomes in C. canephora were duplicated using colchicine (Monaco et al 1975). In comparison with Catuaí, a dwarf C. arabica variety resulting from a cross between Mundo Novo and the dwarf variety Caturra, Icatu seedlings that had been slowly acclimated to cold showed the greatest ability to control oxidative stress damage by enhancing enzyme activities (Cu, Zn-SOD and ascorbate peroxidase), increasing the contents of antioxidant molecules (ascorbate, alpha-tocopherol and chlorogenic acids), lowering the reactive oxygen species contents (H 2 O 2 and OH • ) and also increasing the expression of genes coding for GR, dihydroxy ascorbate reductase and class III and IV chitinases (Fortunato et al 2010).…”

-(Antioxidative responses of cell suspension cultures of two Coffea arabica varieties to low aluminum levels at pH 5.8). The effects of aluminum (Al) on the activities of antioxidant enzymes and ferritin expression were studied in cell suspension cultures of two varieties of Coffea arabica, Mundo Novo and Icatu, in medium with pH at 5.8. The cells were incubated with 300 μM Al 3+ , and the Al speciation as Al 3+ was 1.45% of the mole fraction. The activities of superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST) were increased in Mundo Novo, whereas glutathione reductase (GR) and guaiacol peroxidase (GPOX) activities remained unchanged. SOD, GR, and GST activities were increased in Icatu, while CAT activity was not changed, and GPOX activity decreased. The expression of two ferritin genes (CaFer1 and CaFer2) were analyzed by Real-Time PCR. Al caused a downregulation of CaFER1 expression and no changes of CaFER2 expression in both varieties. The Western blot showed no alteration in ferritin protein levels in Mundo Novo and a decrease in Icatu. The differential enzymes responses indicate that the response to Al is variety-dependent.
