Abstract
Rose is one of the most important cut flowers all over the world as well as in Korea.
Growers in Korea are exclusively relying on foreign cultivars.
A rose breeding programme was started a decade ago in Korea.
Lack of knowledge lead to a number of research topics for Korean researchers.
One of these topics is the low germination rate in rose seeds which is in general about 20%. High amounts of substances that inhibit germination were found in the pericarp of the achene.
Four different treatments such as scarification (0, 1, 5, and 10 min), UV-irradiation (0, 5, 10, 20, and 30 min), immersion in surphuric acid (0, 5, and 10 min) and microorganism (Klebsiella oxytoca C1036 treatment for 0, 1, and 48 h), were applied to improve germination rate.
Only microorganism treatments (1 and 48 h) were successful in improving germination rate by two times compared to the control.
Presently several other microorganisms are being tested
