Rainfall extremes modeling under shortage of data and uncertainty in the Pampean region (Argentina) by Puricelli, Marino Marcelo

“…The assessment of the surface runoff capacity of storms is essential for the design of drainage infrastructure, for the management of rainfall excesses and the control of soil erosion. The knowledge of precipitation intensity values at scales larger than the daily is a key in this process. …”

Assessing the Impact of Ramularia Leaf Spot on Barley: Prospects for Fungicide Protection Strategies and Weather-Based Prediction Models in Argentina by Erreguerena, Ignacio Antonio, Quiroz, Facundo Jose, Cambareri, Matias, Pereyra, Silvia, Havis, Neil David, Carmona, Marcelo Anibal

“…Four possible forecast models were proposed based on the daily average temperature accumulated from early tillering (GS21) to GS39 stage, in combination with the number of days of soil water availability, number of days with water excess and duration of leaf wetness or accumulated rainfall from tillering to GS39 (n = 10).…”

Potato leaf senescence affects the olfactory and feeding preferences of the green peach aphid, Myzus persicae by Lopez-Gialdi, Agustín I., Nussenbaum, Ana Laura, Fernandez, Paula Del Carmen, Segura, Diego Fernando, Fernandez, Patricia Carina, Di Rienzo, Julio, Machado Assefh, Cristina Renata, Álvarez, Adriana E.

“…Additionally, non-senescent apical leaves of mature plants released significantly higher levels of β-caryophyllene compared to senescent leaves, likely reflecting an overall increase in volatiles emission. CONCLUSION: The results suggest that senescence induction, rather than natural senescence, enhances the nutritional quality of the leaves, allowing aphid propagation. …”

Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids by Zegada Lizarazu, Walter, Luna, Dario Fernando, Monti, Andrea

“…The higher cold tolerance of Bulldozer was partially related to a more efficient photochemical regulation mechanism of the incoming light energy: the higher tolerance of photosystem II (PSII) to photo‐inactivation was because of a more effective dissipation capacity of the excess of energy and to a more balanced diversion of the absorbed energy into alternative energy sinks. …”

High methane uptake from soils of low and high density radiata pine afforestations compared to herbaceous systems by De Bernardi, María, Priano, María Eugenia, Fusé, Victoria, Fernandez, María Elena, Gyenge, Javier, Guzmán, Sergio, Julianera, María

“…Results suggest that the low tree density afforestations, suitable for silvopastoral use, have a functional role (CH4 uptake) similar to that of dense forests, and could be a good option to mitigate CH4 emissions by livestock and agricultural sector.…”

Effect of extended maceration and ethanol concentration on the extraction and evolution of phenolics, colour components and sensory attributes of Merlot wines by Casassa, Luis Federico, Beaver, Christopher W., Mireles, María S., Harbertson, James F.

“…The relationship between the chemical and sensory data was explored with P artial L east S quare R egression. EtOH concentration differing by 1.2% v/v had no effect on tannin and anthocyanin extraction, colour, tannin mean degree of polymerisation, polymeric pigment formation and recovery of anthocyanins and tannins in the pomace after maceration. …”
