摘要

本研究旨在研究纳米硒(nano-Se)对伊朗濒危药用植物vasha (Dorema amiacum)萌发特性的影响。实验采用完全随机双因素试验，采用5种浓度(0、5、10、20和40 mg L -1)的纳米硒和4℃的种子预冷处理。纳米硒处理提高了种子的发芽率、平均发芽率和活力指标(p <0.05)。其中，预冷与20 mg L -1纳米硒调质组合处理在提高种子萌发和幼苗生长特性方面效果最好。综上所述，纳米硒预处理和预冷处理可促进菊苣种子萌发。

Effect of prechilling and nano-selenium on seed germination of Dorema ammoniacum

The aim of this research was to investigate the effectiveness of nano-selenium (nano-Se) on germination properties of vasha ( Dorema ammoniacum ), an endangered medicinal plant in Iran. The experiment was conducted in a completely randomised two-factor, experiment with five concentrations (0, 5, 10, 20, and 40 mg L -1 ) of nano-Se and seed prechilling treatment (4°C). All the germination characteristics, including percentage germination, mean germination and vigour indices were improved by nano-Se treatments ( p < 0.05). Among the treatments, the combination of prechilling and 20 mg L -1 nano-Se conditioning was the best treatment, both in improving germination and the growth characteristics of seedlings. It can be concluded that pretreatment of seeds with nano-Se and prechilling can be used for promoting germination of D. ammoniacum seeds.
