Eragrostis spectabilis is used as an ornamental grass in China.But some research reported that it had high potential risk of bccoming invasive.Usually successful exotic weeds had strong reproduction ability.And for now, germination characteristics of Eragrostis spectabilis seeds have not been reported.Effects of temperature, light, water stress and soil depth on Eragrostis spectabilis seeds germination were studied by petri dish and pot experiments in germination box and glasshouse.The results showed that the positive germination temperatures were between 17.7℃ and 43.2℃, with the best temperature of 39.2℃.Light was preferred for seed germination, the germination percentage was relatively higher under continuous light condition than continuous dark condition.PEG6000-simulated water stress significantly inhibited the germination.When water potential decreased to-8.0 bar, seeds could not germinate.The soil depth of 0.5 cm was ideal for germination and the germination percentages from 0-1 cm were more than 60%.The germination percentage decreased significantly with the increase of soil depth during 1-4 cm.This research indicated that environment condition has significant influence on seed germination of Eragrostis spectabilis.The spreading and infestation of this grass might be managed by regulating its seed germination.
