Development and recovery of iron deficiency by iron resupply to roots or leaves...
Pestana, M.; Correia, P. J.; Saavedra, Teresa; Gama, Florinda; Abadía, Anunciación; Varennes, Amarilis deBare-root transplants of strawberry (Fragaria ananassa Duch. cv. ‘Selva’) were transferred to nutrient solutions with or without iron (Fe). After six weeks of growth, plants grown in solution lacking Fe were chlorotic and showed morphological changes in roots typical of Fe deficiency. Subsequently, four treatments were applied for nine days: plants grown in continued absence of Fe (Fe0); plants grown in continu...
The root ferric-chelate reductase of Ceratonia siliqua (L.) and Poncirus trifol...
Pestana, M.; Gama, Florinda; Saavedra, Teresa; Varennes, Amarilis de; Correia, P. J.Iron (Fe) deficiency is a common nutritional disorder in several crops grown in calcareous soils, but some species are well adapted to these conditions. A hydroponic experiment was conducted to compare the response of a calcicole species Ceratonia siliqua L. (carob) and of Poncirus trifoliata (L.) Raf., a citrus rootstock very sensitive to Fe deficiency. Rootstocks from both species were grown in nutrient solut...
A caracterização e correção da deficiência de ferro em plantas de morangueiro: ...
Pestana, Maribela; Gama, Florinda; Saavedra, Teresa; Pinto, João Castro; Abadia, Anunciación; Varennes, Amarilis de; Correia, Pedro JoséIron (Fe) is abundant in soils and although it is required in small amounts by plants the incidence of iron chlorosis (Fe deficiency) is very common in a number of crops and requires massive soil application of Fe-chelates to correct it. In this work, we present the most important results obtained in several experiments conducted with strawberry to study the physiological and biochemical response mechanisms to ...
