Cherry seeds need both warm and cold stratification to overcome the seed's dormancy. But you can germinate fresh cherry seeds using the plant hormone Gibberellic acid.
In March 1969, partially stratified (3 months) seed
from 14 families were removed from cold storage,
endocarps were removed by cracking, and 10 to 20
seeds from each family were assigned to each of the
following three treatments:
- Control: 18-hour soak in distilled water, followed
by a 20-minute soak in Captan (1 gram per liter of water).
- Gibberellic acid: 18-hour soak in 100-p.p.m. GA3.
- Gibberellic acid-Captan: 18-hour soak in 100-p.p.m.
GA„ followed by 20-minute soak in Captan.
After treatment, seeds were planted approximately 5
mm. deep in flats of coarse sand, treated with Pan-ODrench
.3 Flats were placed in a greenhouse and watered
with distilled water as needed to keep the sand moist.
The following germination percentages were observed 3
weeks after planting:
GA3 stimulated germination, but Captan did not
significantly enhance this effect or prove essential in
reducing seed infection. After germination was
evaluated, seedlings were gently washed from the sand
and transplanted to loam-filled clay pots where about 95
percent of them developed into normal plants.
In a second test, conducted in late summer with
freshly collected fruit, seed from five trees were given the
same three treatments used above. The experiment was
a randomized complete block with five 10-seed
replications of each tree-treatment combination. Mean
germination percent at 3 weeks was almost identical to
that in the previous test:
