Blue light attenuation mediates morphological and architectural acclimation of Vitis vinifera cv. Malbec to shade and increases light capture
Gonzalez, Carina Veronica; Jeréz, Damián Nicolás; Jofre, María Florencia; Guevara, Aranzazù; Prieto, Jorge Alejandro; Mazza, Carlos Alberto; Williams, Larry E.; Giordano, Carla Valeria (2018-10)Grapevine is one of the most important fruit crops worldwide. Vineyard management practices affect light interception and spectral characteristics inside the canopy. Plant photoreceptors drive shade acclimation responses ... -
Effect of leaf‐to‐fruit ratios on phenolic and sensory profiles of Malbec wines from single high‐wire‐trellised vineyards
Ahumada, Gastón E.; Catania, Anibal Alejandro; Fanzone, Martín Leandro; Belmonte, Marcelo J.; Giordano, Carla Valeria; Gonzalez, Carina Veronica (Wiley, 2020-08)BACKGROUND: The single high‐wire system is a free canopy trellis system suitable for warm to hot climates. In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. ... -
Grapevine morphological shade acclimation is mediated by light quality whereas hydraulic shade acclimation is mediated by light intensity
Gonzalez, Carina Veronica; Prieto, Jorge Alejandro; Mazza, Carlos Alberto; Jeréz, Damián Nicolás; Biruk, Lucía N.; Jofre, María Florencia; Giordano, Carla Valeria (Elsevier, 2021-06)Plants acclimate to shade by sensing light signals such as low photosynthetic active radiation (PAR), low blue light (BL) levels and low red-to-far red ratios (R:FR) trough plant photoreceptors cross talk. We previously ... -
Morphology and hydraulic architecture of Vitis vinífera L. cv. Syrah and Torrontes Riojano plants are unaffected by variations in red to far-red ratio
Gonzalez, Carina Veronica; Jofre, María Florencia; Vila, Hernan Felix; Stoffel, Markus; Bottini, Ambrosio Rubén; Giordano, Carla Valeria (2016)Plants have evolved an array of specific photoreceptors to acclimate to the light environment. By sensing light signals, photoreceptors modulate plant morphology, carbon- and water-physiology, crop yield and quality of ...
