The Dormancy Types and Germination Characteristics of the Seeds of Berberis koreana Palibin, an Endemic Species of Korea

Berberis koreana Palibin is an endemic plant native to Korea. In this study, we aimed study the seed germination of species using a water imbibition experiment, gibberellic acid (GA3) treatment (0, 10, 100, or 1000 mg·L−1), cold stratification 2, 4, 8, 12 weeks at 4 °C), move-along and phenology studies. weight seeds increased by more than 120% in 24 h. An analysis internal external morphological characteristics revealed that embryo was already fully grown from fruit did not grow thereafter. The final percentages for 0, °C were ± 3.65, 32 9.09, 59 1.00, 9.59, 71 1.91%, respectively. experiment studies, longer low-temperature period resulted higher percentage. However, GA3 had little effect on germination. Our results indicate B. exhibits intermediate physiological dormancy.
