Appeal No. 1999-1298
Application No. 08/667,167
(ii) drying the primed seeds for not more than 24 hours to a
moisture content of about 3 to 20% units lower than the moisture
content of non-incubated primed seeds of the same species and
maintaining the seeds in a container with minimal air and moisture
exchange for about 1 to 7 days at a temperature range of about 3° to
40°C;
(iii) exposing the primed seeds to an osmoticum solution for
about 1 to 7 days within the range of about –0.5 to about –0.4 MPa;
(iv) exposing the primed seeds to a heat shock at a
temperature in the range of about 25° to 45°C for about 1 to 5 hours;
and
(v) a combination of substeps (i) or (ii) or (iii) and (iv) above;
and
b) obtaining incubated primed non-germinated seeds wherein the
seed has a moisture content about 3 to 20% units lower than the moisture
content of nonincubated primed non-germinated seeds of the same plant
species and the incubated primed seeds have a prolonged shelf life without
loss of viability as compared to the viability of nonincubated primed non-
germinated seeds of the same plant species.
59. A process for prolonging the shelf life of primed non-germinated
seeds comprising the steps of:
a) incubating primed non-germinated seeds by exposing the seeds to
a heat shock from about 1 to 5 hours at a temperature range of 25° to 45°C;
b) obtaining incubated primed seeds wherein the seed has a
moisture content about 3 to 20% units lower than the seed moisture content
of nonincubated primed non-germinated seeds of the same plant species;
and
c) storing the incubated seeds at a temperature in the range of about
3° to 25°C and at a relative humidity of 20 to 90%
wherein the incubated seeds have a prolonged shelf life without loss of viability as
compared to the viability of the nonincubated primed non-germinated seeds of the
same plant species.
