Correlation between the color, size and shape of Israeli crucifer flowers and relationships to pollinators

Analysis of 89 crucifer species shows a close connection between flower color and several other flower traits. Violet flowers are large (mean corolla diameter 6.7±3.26 mm) and have a tube. Yellow flowers are smaller (3.53±2.0 mm) and open without a tube. White flowers are similar to the yellow flowers but smaller (2.08±1.2 mm). In general, the pollinators of violet flowers are large long-tongued bees, and the pollinators of yellow and white flowers are small short-tongued bees and flies. Color is thus a communicative flower trait highly correlated with mode of pollination in the Israeli crucifers. -from Authors
