“…CI is a physiological disorder of fruits and vegetables caused by low temperatures (below a threshold level) for too long a time, resulting in metabolic dysfunction and, finally, visible chilling symptoms. CI negative effects on quality of cold‐sensitive fruits include internal browning, reduced hardness and colour, and aroma degradation . CI is characterized by changes in membrane structure and composition that lead to a loss of permeability control and metabolic disorders .…”

“…However, despite some works on cotton, flowers, and fruits (Serek et al, 2006;De Pietro et al, 2010;Chen et al, 2015;Li et al, 2016), there is no knowledge of researches on the effect of 1-MCP on soybean, aiming to the attenuate negative effects of ethylene induced by drought stress on plant senescence, including nodules. This strategy could help plants to cope with periods under water restriction and reduce the negative effects on BNF.…”

“…Compounds like 1-methylcyclopropene (1-MCP) compete with ethylene for binding sites in cell receptors and block the cascade of events associated to ripening and senescence (Li et al, 2016). Based on this information, the use of an inhibitor of ethylene might attenuate the effect of drought on plants.…”

-The objective of this work was to assess the effects of 1-methylcyclopropene (1-MCP) on traits related with biological nitrogen fixation on 'BRS 268' soybean (Glycine max) subjected to water restriction. Plants were either exposed to drought between 32 (R 2 ) and 47 (R 3 ) days after sowing (DAS) or kept well-watered, in combination with exposure or not to 1-MCP. On the second day under drought (34 DAS), plants from both water conditions were exposed to 1-MCP in a hermetically sealed chamber for 15 hours. Control plants, dry or well-watered, that were not exposed to 1-MCP were kept in a separate chamber. At 36 (R 2 ) and 47 (R 3 ) DAS, shoot and root dry weights, leaf area index, number and dry weight of nodules, total ureides in sap, and N concentration in leaves were assessed. From 47 DAS on, extra plants were well watered until physiological maturity (R 8 ) and assessed for yield components. Water restriction increased ureides in sap and reduced N in leaves in R 2 ; reduced the number and mass of nodules, shoot dry weight, and leaf area index in R 3 ; and reduced the number of pods and seed mass of plants not exposed to 1-MCP. However, when plants are exposed to 1-MCP, there is an attenuation of water restriction effects.Index terms: Bradyrhizobium, Glycine max, inhibitor of ethylene, nodulation, water stress. Fixação biológica do nitrogênio em soja sob restrição hídrica e exposta ao 1-metilciclopropenoResumo -O objetivo deste trabalho foi avaliar os efeitos do 1-metilciclopropeno (1-MCP) em parâmetros relacionados à fixação biológica de nitrogênio em soja (Glycine max) 'BRS 268' submetida à restrição hídrica. As plantas foram submetidas à seca entre 32 (R 2 ) e 47 (R 3 ) dias após a semeadura (DAS) ou mantidas bem irrigadas, em combinação com exposição ou não ao 1-MCP. No segundo dia sob seca (34 DAS), as plantas de ambas as condições hídricas foram expostas ao 1-MCP em câmara hermeticamente fechada por 15 horas. As plantas-controle, sob restrição hídrica ou bem irrigadas, não expostas ao 1-MCP foram mantidas em câmara separada. Aos 36 (R 2 ) e 47 (R 3 ) DAS, foram avaliados massa seca da parte aérea e das raízes, índice de área foliar, número e massa seca de nódulos, ureídos totais na seiva e concentração de N foliar. A partir dos 47 DAS, as plantas remanescentes foram mantidas bem irrigadas até a maturação fisiológica (R 8 ) e os componentes de produção foram avaliados. A restrição hídrica aumentou os ureídos na seiva e reduziu o N foliar em R 2 ; reduziu o número e a massa de nódulos, a massa seca da parte aérea e o índice de área foliar em R 3 ; e reduziu o número de vagens e a massa de sementes em plantas sem exposição ao 1-MCP. No entanto, quando as plantas são expostas ao 1-MCP, há atenuação do efeito da restrição hídrica.Termos para indexação: Bradyrhizobium, Glycine max, inibidores de etileno, nodulação, estresse hídrico.

Chilling Injury in Tropical Crops after Harvest

Tropical crops suffer from chilling injury after harvest, which has historically limited their global trade. The primary cause of chilling injury relates to membrane dysfunction leading to altered Ca2+flux and upregulation of cold‐regulated genes via C‐repeat binding factors (CBFs). Secondary damage results from generation of free radicals. Chilling injury leads to a diversity of internal and external symptoms in tropical crops. The most serious are those which occur only internally or take time to display after fresh products leave the chilling environment, as these symptoms are likely to lead to product rejection after purchase. Techniques for the detection of chilling injury by non‐destructive technologies are reviewed. A wide range of techniques has been tested empirically for reducing chilling susceptibility in tropical crops (step‐down cooling, hormetic treatments, intermittent warming, atmosphere modification, chemical treatments, and pre‐harvest manipulation) and is reviewed here. Faster progress may be possible if treatments can be based on knowledge of underlying mechanisms; for example, maximal heat shock protein gene expression may be an indicator of effective heat treatments. Options for introducing greater chilling tolerance through breeding are discussed, using wild relatives or introduced CBFs. Improved technologies are already leading to increased trade in tropical products which is beneficial for tropical economies.
