The Dormancy Types and Germination Characteristics of the Seeds of <i>Berberis koreana</i> Palibin, an Endemic Species of Korea
<i>Berberis koreana</i> Palibin is an endemic plant native to Korea. In this study, we aimed to study the seed germination of this species using a water imbibition experiment, gibberellic acid (GA<sub>3</sub>) treatment (0, 10, 100, or 1000 mg·L<sup>−1</sup>), col...

| description | <i>Berberis koreana</i> Palibin is an endemic plant native to Korea. In this study, we aimed to study the seed germination of this species using a water imbibition experiment, gibberellic acid (GA<sub>3</sub>) treatment (0, 10, 100, or 1000 mg·L<sup>−1</sup>), cold stratification (0, 2, 4, 8, or 12 weeks at 4 °C), move-along experiment, and phenology studies. In the water imbibition experiment, the weight of the seeds increased by more than 120% in 24 h. An analysis of the internal and external morphological characteristics of the seed revealed that the embryo was already fully grown from the fruit and did not grow thereafter. The final germination percentages for the cold stratification at 0, 2, 4, 8, and 12 weeks at 4 °C were 12 ± 3.65, 32 ± 9.09, 59 ± 1.00, 59 ± 9.59, and 71 ± 1.91%, respectively. In the move-along experiment and phenology studies, a longer low-temperature treatment period resulted in a higher germination percentage. However, the GA<sub>3</sub> treatment had little effect on the seed germination. Our results indicate that <i>B. koreana</i> exhibits an intermediate physiological seed dormancy. |
