Hazelnut or Fibert:Corylus avellana L.
Contents
Botanical description:Corylus avellana L.:
A. Plant: Large shrubs (10-15 ft) in Europe, but trained to a single trunk in the Pacific Northwest to facilitate mechanical harvest. Trees begin bearing when 3-4 years old, and can bear for up to 40-50 yr. Trees commonly produce 20-25 lbs of dried nuts each. Leaves are 2-3" long, broadly ovate, acuminate, slightly lobed with doubly serrate margins.
B. Flowering, pollination: Monoecious, dichogamous habit, female flowers are borne in head-like inflorescences terminally on short shoots developing from lateral buds on 1-yr wood (borne on current season's growth, although it appears to be 1-year-old wood as extension growth at flowering is severely limited). Male catkins are borne from unmixed lateral buds on 1-yr wood. Most filberts are self-unfruitful.
C. Flowering habit is unusual. Both and flowers are initiated the summer prior to harvest. Female flowers lack perianth and ovaries at the time of pollination in mid-January to mid-February; the pollen tube grows to the base of the style and becomes quiescent until 5-6 months later (June), when the ovary and ovule develop. Fertilization then takes place in July, and the nut rapidly develops, maturing by late August.
D. Fruit: a nut in clusters of 1-12; shape varies from round to oval, to oblong, and resembles the appearance of an oak acorn. The pericarp is hard, loosely covering the smooth to shriveled kernel. Nuts are surrounded by a green, leafy husk (involucre), and abscise from the base of the husk in late august. However, the husk does not release the nut until 6 weeks later when it dries and opens.
Main Varieties: Improved Varieties: Round de Piemont, Fertile de Coutard (Barcelona), Longued Espagne, Segorbe, Negiret Deviana, Coxford and Merveille de Bollwiller.
Form of Consumption: Fresh and Dried Fruit, Confectionary and Chocolate industries
Industrial and Medicinal Uses: Production of Edible oil, Lubrication oil and soap industries.
