Breaking seed dormancy and germination in Prunus avium
Author(s):
Abstract:
Wild cherry (Prunus avium) is a native fast growing broadleaved tree in Hyrcanean forests producing valuable wood. Prunus seeds have long dormancy and there is variety of methods for breaking dormancy of its seed. This study was conducted in order to overcoming dormancy and germination of Prunus seed. For this purpose, seeds were collected from Aliabad Katool region in forests of Golestsan province, north of Iran. The seeds with mosocarp, without mesocarp and without endocarp were subjected to warm stratification (4 weeks, 20 ˚C) followed by cold stratification (10 weeks, 5 ˚C). Results showed that mesocarp and endocarp had significant effects on overcoming seed dormancy and germination characteristics. Germination percent, germination speed and germination value in seeds stratified without endocarp were greater than those in seeds stratified with mesocarp and without mesocarp. The results revealed that the seeds without endocarp were the most favorable treatment to break dormancy and to improve germination characteristics in Prunus avium seeds.
