Theoretical approach to predicting petal wettability

This model predicts petal surface wettability by considering the additive effects of the geometries of the epidermal cells and the structured cuticle.

Theoretical approach to predicting petal wettability

If the surface of a petal remains wet for an excessive amount of time the flower’s attractiveness to floral visitors may be impaired, and adhesion of pathogens may be promoted. Taneda et al. develop a thermodynamic model to predict surface wettability by considering the additive effects of the geometries of the epidermal cells and the structured cuticle. The model indicates that petal wettability depends on the height and interval between cuticular steps, and on a height-to-width ratio for epidermal cells if a thick hydrophobic cuticle layer covers the surface. If the surface is covered with thin cuticle layer, the petal is highly wettable irrespective of the roughness of the surface. These predictions are supported by the measurements of petal wettability made on flowers of seven herbaceous species.

  • Petal geometric is an emerging research area in plant biology & the article titled “Theoretical approach to predicting petal wettability” by author Alex is amazing since it provide evidence of how cell arrangements in a tissue reflect complex but rather useful mathematical approach in understanding morphological features of certain plant parts like petals. Research has previously shown importance of biophysics in cell expansion processes but this article is beautifully illustrating the use of mathematical geometrics in plant structure & function. Thanks for posting this article.
