Secondo uno studio condotto da un team di ricerca dell’Università di Tel Aviv su alcune piante di primula della sera, ci sarebbe una correlazione tra l’aumento di concentrazione di zucchero nel loro nettare e il ronzio prodotto dal battito d’ali degli insetti impollinatori. Ne parla un articolo pubblicato su The Atlantic.

When people pose the old question about whether a tree falling in an empty forest makes a sound, they presuppose that none of the other plants in the forest are listening in. Plants, supposedly, are silent and unhearing. They don’t make noises, unless rustled or bitten. When Rachel Carson described a spring bereft of birds, she called it silent. But these stereotypes may not be true. According to a blossoming batch of studies, it’s not that plants have no acoustic lives. It’s more that, until now, we’ve been blissfully unaware of them.

The latest experiments in this niche but increasingly vocal field come from Lilach Hadany and Yossi Yovel at Tel Aviv University. In one set, they showed that some plants can hear the sounds of animal pollinators and react by rapidly sweetening their nectar.
