北方野花（Clintonia borealis）未授粉花的花蜜分泌。（百合科）在花被片首次开放时开始，在花药开裂时达到高峰，在花被片开始卷曲后停止。终生产糖量与花的大小高度相关，不受每日采蜜量的影响。甘露浓度随大气相对湿度的波动变化很大。这表明，由于新鲜分泌的克林顿花蜜的含糖量从4到63%不等，除非有采样时和采样前的环境数据，否则不同物种之间的花蜜浓度比较可能没有意义。
Nectar secretion in unpollinated flowers of Clintonia borealis (Ait) Raf. (Liliaceae) began as the tepals first opened, reached a maximum at about the time the anthers dehisced, and ceased after the tepals began to curl back. Total lifetime sugar production was highly correlated with flower size and was not affected by daily nectar removals. Nectar concentration varied widely as a response to fluctuations in atmospheric relative humidity. It is suggested that since freshly secreted Clintonia nectar ranged in concentration from 4 to 63% sugar by weight, comparisons of nectar concentration among different species may not be meaningful unless accompanied by environmental data at and prior to the time of sampling.
