Kaolin particle film application stimulates photoassimilate synthesis and modif...
Conde, Artur; Neves, Andreia; Breia, Richard; Pimentel, Diana; Dinis, Lia-Tânia; Bernardo, Sara; Correia, Carlos Manuel; Cunha, Ana; Gerós, H.Water scarcity is associated with extreme temperatures and high irradiance, and significantly and increasingly affects grapevine yield and quality. In this context, the foliar application of kaolin, a chemically inert mineral that greatly reflects ultraviolet and infrared radiations, as well as, in part, photosynthetically active radiation, has recently been shown to decrease photoinhibition in mature leaves. H...
Aluminium long-term stress differently affects photosynthesis in rye genotypes
Silva, Sónia; Pinto, Glória; Dias, Maria Celeste; Correia, Carlos Manuel; Moutinho-Pereira, José; Pinto-Carnide, Olinda; Santos, ConceiçãoThe ability of crops to overcome Al toxicity varies among crop species and cultivars. Among the Triticeae genus, rye (Secale cereale) is considered the most Al-tolerant species. In the present work, two rye genotypes differing in Al tolerance ('Riodeva': Al-sensitive and 'Donkowsky Zlote': Al-tolerant) were exposed to 1.11 and 1.85 mM Al during three weeks. Growth, water status and photosynthesis related parame...
