Merhaba
Aşağıda Cranberry tohumunun çimlendirilmesi hakkında bir yazı var.İngilizce bilen arkadaşlardan yardım bekliyorum.İlginize teşekkür ederim.Selamlar
Vaccinium macrocarpon
American Cranberry
Type:Evergreen Shrub
USDA Growing Zone : 2 - 8
Germination : 365 + days
Storage : Keep Refrigerated
Cultivation notes
Scarrification : Soak in water,let stand in water for 24 hours.
Stratification : Cold stratify for 90 days.
Germination : Surface sow on peaty soil and keep moist,cover seedbed with some shade.
Other :Can be slow germinate so be patient! Seeds sown in the fall may not germinate until the following fall.
2 - 3 years to fruit.

Scarification, Cold and Warm Stratification

Success with certain seeds depends as much on the treatment before sowing as the method of sowing.
Seeds may need treating to break dormancy.Seeds that have not germinated in the first season should be left for a further
year as they may germinate in the second spring after sowing.

Scarification
Trees with hard seeds coats,such as Robinia should be scarifield to allow in moisture.
Scarification can be carried out using sandpaper or a file to abrade the seed coat,
or using a knife to nick the coat.Some seeds can be softened in warm water by soaking
for 24 hours ; care should be taken when soaking seeds ,as rotting may be the end result.

Stratification
This is used for seeds which respond to either heat or cold.Stratifying will break dormancy by copying the conditions
to which the seeds are normally subjected.Most commonly this is a spell of cold similar to that experience in the winter
but with more reliable results.A few seeds have a multiple dormancy,germinating in the second spring after ripennig with a spell
of warmth in between,for example Fraxinus(ash).Subjecting seeds to a warm spell followed by cold can increase germination in the first spring.

Cold moist stratification
Place seeds in a clear plastic bag filled with moist but not wet coir,composted bark,or a mix of equal parts of the above with
coarse sand,perlite or vermiculite and seal the bag.Chill seeds in a refrigerator,keep bellow 40 F for four to 20 weeks,depending on the species.
Shake the bag periodically,and sow seeds immediately if it germinates in the bag.

Warm moist stratification
Place seeds in a bag as above and keep in a warm place at 65 - 75 F for up to 12 weeks,before giving a period of cold stratification.
Alternatively sow in pots and place in a heated propagator for the required spell.Following this place in a cold frame for the winter.

Sowing seeds in containers
This is easiest way of sowing tree seeds.Generally,choose a free-draining soil less compost for seeds quick to germinate and a loam - based
compost for seeds slow to germinate.Cover seeds with fine grit or perlite to a depth of 1/4 in.Place seeds where they will receive the appropriate
minimum temperature,e.g. A cold frame or greenhouse.Transplant seedlings as soon as large enough to handle and harden off.
It is best to use Rootrainers or deep pots,and plant out seedlings as soon as possible.This will avoid too much root disturbance or letting
roots becoming pot bound which will reduce establishment.
