摘要：

以海边月见草为材料，探讨收集自12个地区的海边月见草种子其最佳萌发条件，试验采用正交试验设计，以露地播种的作为对照进行。试验结果表明：（1）12个地区的海边月见草以沙土播种的出苗率最高，基质对各地区海边月见草种子的萌发影响显著；（2）温度与基质含水量对出苗率影响各不相同。在30℃、50%基质含水量的条件下，厦门椰风寨地区海边月见草种子发芽率达到74%。在10℃、10%含水量的条件下，惠安山霞和漳浦赤湖镇亭里村两地的海边月见草发芽率最高，其中赤湖镇亭里村的海边月见草发芽率达到70%；在20℃、30%基质含水量的条件下，长乐漳港等9个地区的海边月见草发芽率均达到最高值，其中连江地区海边月见草的发芽率达到81%。

Abstract:

This study, using orthogonal experimental design, collected Oenothera littaralis Schlectsfrom 12 different regions and studied the best germination conditions，in control of outdoor sowing. The results showed that: (1) germination percentage in sand sowing was the best during 12 regions. Matrix effected Oenothera littaralis Schlect. seeds germination remarkable in each region. (2)Temperature and substrate water content on the different regions effected Oenothera littaralis Schlect seeds emergence rate differently. At 30℃, 50% substrate moisture conditions, Xiamen Fengyezai area Oenothera littaralis Schlect seeds germination rate was 74%. At 10℃, 10% moisture content conditions, Huianshanxia and Tingli village in Zhangpuchihu town had highest germination rate, in which the Oenothera littaralis Schlect germination rate of Red Pavilion Village reached 70%; At 20℃, 30% substrate moisture conditions, Oenothera littaralis Schlect germination rate in 9 districts such as Changle city and Zhanggang town reached its peak value, of which the Lianjiang region Oenothera littaralis Schlect germination rate was 81%.
