Germination. Apple seeds display dormancy which
has been overcome by cold stratification (table 4).
Stratification is achieved by placing the seeds in a moist
medium and storing at a temperature of 2 to 5 °C. A minimum
of about 30 days under stratification conditions is
required to remove embryonic dormancy (Zhang and
Lespinasse 1991). After stratification, apple seeds exposed
to diurnally alternating day/night temperatures of 30/20 °C,
germinated in 30 to 60 days (table 4). Germination is
epigeal (figure 3).
