Edible Uses
Edible Parts: Oil;  Seed.
Edible Uses: Oil.

Seed - raw or cooked[2, 22, 46, 105]. Rich in oil. As nice a flavour as C. avellana, the common hazel nut[146, 158]. The seed ripens in mid to late autumn and will probably need to be protected from squirrels[K]. When kept in a cool place, and not shelled, the seed should store for at least 12 months[K]. An edible oil is obtained from the seed.

Oil;  Wood.

Wood - firm, durable, moderately hard. Used for furniture, turnery etc[74, 158].
Cultivation details
Management: Standard;  Regional Crop;  Staple Crop: Protein-oil.

Landscape Uses:Firewood, Specimen, Street tree. An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility[11, 200]. It does less well in rich heavy soils or poor ones[11, 63]. Does well in a loamy soil[11]. Very suitable for an alkaline soil[11], but it dislikes very acid soils[17]. Tolerates a pH in the range 5.3 to 7.3. Once established, this is a very drought resistant tree[183]. It does not produce suckers[183]. Plants are fairly wind tolerant[1, 11]. A very ornamental tree[1]. Members of this genus bear transplanting well and can be easily moved even when relatively large[11]. The Turkish hazel is occasionally cultivated for its edible seed[46, 61, 158]. This species is also useful in hybridizing with C. avellana in order to develop superior fruiting cultivars[183]. Special Features:Not North American native, Inconspicuous flowers or blooms.
Propagation
Seed - best sown as soon as it is harvested in autumn in a cold frame[164]. Germinates in late winter or spring. Stored seed should be pre-soaked in warm water for 48 hours and then given 2 weeks warm followed by 3 - 4 months cold stratification[164]. Germinates in 1 - 6 months at 20°c[164]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame or sheltered place outdoors for their first winter. Plant them out into their permanent positions in late spring or early summer[K]. Layering in autumn. Easy, it takes about 6 months[78, 200].

very helpfull thankyou, i needed some of this information for my course work. in my opinion it is clear and easy to read, but the only thing bad i will say is that you should put significant pests and diseases of this tree on there and you should have the basic maintenance of the tree when it is young, and a few pictures wouldnt go amiss either.

In kashmir condition Corylus colurna is found in ample amount, i have tried its propagation by sucker cutting in IBA treatment and incourgaging success have been attained. Further its sucker grown on the root hence it is difficult to raise from since it has no fibrous root. A part of previous wood helps for rooting .
