Quality and fruit colour change in Verna lemon
While most lemon cultivars in the northern hemisphere are harves¬ted in autumn-winter, Verna, an autochthonous Spanish cultivar, is harvested later (February to August), supplying the European market when lemons are in short supply, a market that is also served by imports from the southern hemispher...
