摘要

研究了氯化钙(CaCl2)和聚乙二醇(PEG)对韩国重要野生蔬菜黄豆(Aruncus dioicus, A. dioicus)萌发特性的影响。检查的因素包括三个启动浓度和持续时间。结果表明，萌发条件对菊苣的萌发特性有一定的影响。一般来说，与对照和CaCl2种子激发相比，PEG种子激发的萌发率、能量、率和达到50%发芽率(T50)的时间都更高。在本研究的实验条件中，在−1.03 MPa条件下用PEG预处理24小时，发芽率最高，是对照的1.9倍。与对照相比，萌发能显著提高，T50值显著降低。这些结果表明，特定的PEG启动条件可以成功地提高菊苣的萌发性能。

The effect of seed priming on the germination properties of Aruncus dioicus

The effects of calcium chloride (CaCl2) and polyethylene glycol (PEG) seed priming on the germination properties of Aruncus dioicus (A. dioicus), an important wild vegetable obtained from forests in Korea, were investigated. The examined factors consisted of three priming concentrations and durations. Our results clearly showed that the germination properties of A. dioicus were affected by the priming conditions. Generally, seed priming with PEG resulted in a higher germination percentage, energy, rate, and time to achieve 50% germination (T50) compared to control and seed priming with CaCl2. Among the experimental conditions used for this study, pre-treatment with PEG at −1.03 MPa for 24 hours resulted in the highest germination percentage, which was 1.9-fold higher than that of the control. Significantly higher germination energy and lower T50 values were also observed compared to those of the control. These results suggest that specific PEG priming conditions can be successfully used to improve the germination properties of A. dioicus.
