摘要圆锥紫萼藓C.林奈是一个新的世界，热带，亚热带和温带，根茎草，往往是一个优势种的前沙丘和主要沙丘复合体。紫丁香具有低的淡水湿度要求，耐受气溶胶盐雾，具有低的营养水平要求，耐受高的砂温，并提供广泛的砂覆盖。也被称为海燕麦，这种草栖息于移动的和半稳定的沙丘系统，并在捕获沙子和建立初级沙丘方面发挥着重要作用。颖果产量低。然而，通过切割胚乳和浸提颖果来增强发芽。北方种群在发芽前需要冷处理，但南方种群在暴露于具有35/25 ° C热周期的发芽方案之前不依赖于冷处理。
Abstract Uniola paniculata C. Linnaeus is a New World, tropical-, subtropical-, and temperate-zone, rhizomatous grass that is often a dominant species on foredunes and on the primary dune complex. Uniola paniculata L. has low freshwater-moisture requirements, tolerates aerosol salt spray, has low nutrient level requirements, tolerates high sand temperatures, and provides extensive sand coverage. Also known as sea oats, this grass inhabits mobile and semistable dune systems and plays a significant role in trapping sand and building primary dunes. Caryopsis production is low. However, germination is enhanced by cutting into the endosperm and leaching the caryopses. Northern populations require cold treatment before germination, but southern populations are not dependent on cold treatment before exposure to a germination protocol with a 35/25°C thermoperiod.
