Nectar Removal Experiment: Endpoint

The purpose of this experiment was to determine if extrafloral and floral nectar production trade off. The experiment was conducted under glasshouse conditions. Values represent endpoint data from a 50 day experiment. Plant ID is an identifier to distinguish individual plants. Species is the species of Turnera. Treatment is the experimental treatment applied to the plant. EFN is a yes/no variable answering if extrafloral nectar was removed for the duration of the experiment. FN is a yes/no variable answering if floral nectar was removed for the duration of the experiment. Leaves is the number of leaves on the plant. Buds is the number of buds on the plants. nFlowers is the average number of flowers produced each day over three days. FNvol is the three-day average floral nectar volume (uL) produced by the plant. FNconc is the three-day average floral nectar concentration (Brix). FNsugar is the three-day average mass of floral nectar sugar (mg sucrose equivalent) produced by the plant. FNvol_per is the three-day average floral nectar volume (uL) per flower. FNsugar_per is the three-day average mass of floral nectar sugar (mg sucrose equivalent) per flower. nEFN is the three-day average number of active EFN pairs per plant. EFNvol is the three-day average extrafloral nectar volume (uL) produced by the plant. EFNconc is the three-day average extrafloral nectar concentration (Brix). EFNsugar is the three-day average mass of extrafloral nectar sugar (mg sucrose equivalent) produced by the plant. EFNvol_per is the three-day average extrafloral nectar volume (uL) per active extrafloral nectary pair. EFNsugar_per is the three-day average extrafloral nectar sugar mass (mg sucrose equivalent) per active extrafloral nectary pair.

本实验旨在探究花外花蜜（extrafloral nectar）与花内花蜜（floral nectar）的产生是否存在权衡关系。实验于温室条件下开展，所有数值均为该50天实验的终点数据。其中，植株编号（Plant ID）为区分单株植株的唯一标识符；物种（Species）指供试的时钟花属（Turnera）植物；处理组（Treatment）为施加于植株的实验处理类型。花外花蜜移除变量（EFN, extrafloral nectar）为二分类（是/否）变量，用于指示实验全程是否移除植株的花外花蜜；花内花蜜移除变量（FN, floral nectar）为二分类（是/否）变量，用于指示实验全程是否移除植株的花内花蜜。叶片数（Leaves）为单株植株的总叶片数量，芽数（Buds）为单株植株的总芽数量；nFlowers为连续三天每日开花数的平均值。FNvol为植株产生的花内花蜜体积的三日平均值，单位为微升（uL）；FNconc为花内花蜜浓度的三日平均值，单位为白利度（Brix）；FNsugar为植株产生的花内花蜜糖类物质的三日平均质量，单位为毫克蔗糖当量（mg sucrose equivalent）；FNvol_per为单朵花的花内花蜜体积三日平均值，单位为微升（uL）；FNsugar_per为单朵花的花内花蜜糖类物质的三日平均质量，单位为毫克蔗糖当量（mg sucrose equivalent）。nEFN为单株植株平均活跃花外蜜腺对的三日平均值；EFNvol为植株产生的花外花蜜体积的三日平均值，单位为微升（uL）；EFNconc为花外花蜜浓度的三日平均值，单位为白利度（Brix）；EFNsugar为植株产生的花外花蜜糖类物质的三日平均质量，单位为毫克蔗糖当量（mg sucrose equivalent）；EFNvol_per为每个活跃花外蜜腺对的花外花蜜体积三日平均值，单位为微升（uL）；EFNsugar_per为每个活跃花外蜜腺对的花外花蜜糖类物质的三日平均质量，单位为毫克蔗糖当量（mg sucrose equivalent）。
