Features of germination of seeds of the bennet aleppsky in vitro

It is established that bennet seeds keep ability to germination within 6,5 years. After a bookmark on seeds start to sprout on the average in 8 days (fresh faster,      old more slowly). Term of the account of energy of germination should be accepted  for 3 days. Duration of germination fluctuates from 3 days (at fresh seeds) to 50 (at old). Energy of germination and germination are maximum (100 %) at fresh seeds. Gradually decreasing with increase in a period of storage in 4,5 years vigor of germination, and later 7,5 years and germination vanishes. Cold stratification doesn’t improve germination.
