Cerza Citrus limon (L.) Burm. f.Citroník
It originates in the region of Cerza, San Gregorio in Italian Catania. This lemon tree is semi-vigorous with a not too dense crown growing mostly vertically, rather than horizontally. Its branches are thornless and young shoots are green with significant purple touch. The flowers are white with a little of purple and the most typical identification characteristic of this tree are their leaves, which are dark green, with a narrow petiole that can easily be damaged by the wind. Despite these few details, 'Cerza' is extremely productive. It was also micro-inoculated for better growth.
The fruit is egg-shaped, average (120-130g) with a slightly punched out petiole joint and not very obvious nipple shape. Its rind is yellow, grainy and average thick. Pulp is bright yellow, quite juicy and very acidic (over 6% of acids). It is also completely seedless.
In general, this fruit starts ripening late in November. Some sources also claim that it is possible to cross this variety with citron.
