Oliveira, Cristina Moniz; Dionísio, Luís; Neto, Cláudia; Goulão, Luís; Clemente, Josué; Henriques, Jorge; Lourenço, InêsIn order to study the evolution of the quality characteristics of apples cv. Royal Gala under refrigerated air storage, 625 ppb of 1-methylcyclopropene (1-MCP) were applied to the fruits for 24 h at 0 ºC. Fruit samples were analysed after storage and after 7 days at 20 ºC (shelf-life) for titratable acidity, pulp firmness, total soluble solids content and skin colour along a 180 days storage period. The storage...

Oliveira, Cristina Moniz; Alpalhão, André; Neto, Cláudia; Goulão, Luís; Clemente, Josué; Henriques, Jorge; Lourenço, InêsThe effect of 1-methylcyclopropene (1-MCP) treatment on the ripening of ‘Rocha’ pears harvested with different stages of maturity, during a cold storage period of seven months was evaluated. Twenty four hours after harvest, the fruits were treated with 300 ppb of 1-MCP for 24 h at 0 ºC. The fruits were stored under normal atmosphere at 0 ºC and 90-95 % RH. Fruit samples were removed from storage periodically an...
Nitrogen distribution, remobilization and re-cycling in young orchard of non-be...
Neto, Cláudia; Carranca, Corina; Clemente, Josué; Varennes, AmarilisIn newly planted orchards, special attention must be paid to fertilization to build up the permanent structure of the trees so that high yield and fruit quality can be reached later on. Nitrogen (N) plays a major role in the fertilization plan, although few studies have assessed its use efficiency in young nonbearing trees, especially in field conditions. In this work, 1–3 years old ‘Rocha’ pear trees, grafted ...
