epinasty

🗣️

DEFINITION

increased growth on the upper surface of an organ causing it to bend downward, the downward curvature of leaves due to differential growth rates, a nastic movement bending plant parts outward and downward

EXAMPLE SENTENCES

The epinasty of the flower petals allowed better exposure of reproductive organs to pollinators. Scientists observed epinasty in leaves treated with certain herbicides causing abnormal downward curling. The epinasty resulted from faster cell division on the upper surface compared to the lower surface. Botanists documented epinasty as a symptom of plant disease or hormonal imbalance in specimens. The epinasty of heavy flowers caused them to hang downward protecting pollen from rain.
