Bumblebees hurt the leaves of flowers to make them grow faster.

Bumblebees are not only a very annoying element of outdoor recreation for people, but also a very important and even integral part of the plant ecosystem of the world – that is why their role and influence on the pollination process of the vast majority of flowers and plants can not be overestimated. Today, a talented team of microbiologists from the Lausanne Higher Polytechnic School in Switzerland presented their new study on the hitherto undetected role of bumblebees in triggering the process of early and accelerated flowering of some of the flower leaves in cases when there is no pollen around, or when there is very little.
It is widely known that, with the smallest amount of pollen that bumblebees tolerate and with which various flowers and plants are pollinated, the majority of working bumblebees begin to actively plant leaves of many colors – and if previously they had only watched this process without letting it no explanations, then now Swiss scientists have penetrated the secrets of the biological activity of working bumblebees. It turned out that with such an unfavorable factor as the lack of the required amount of pollen, bumblebees-workers begin to pierce some of the leaves of those flowers that did not get pollen.
This is done in order to produce the so-called “stress factor” on the leaves and make them grow faster, overcoming the lack of pollen and even water. Previously, many studies have focused on this property of many colors, but few have realized that bumblebees themselves, which play an important role in their ecosystem, can do the same – in other cases, even on a fairly large scale.
All this sounds really unusual, but in fact it is accomplished with about the same ease as when exposed to various natural chemicals on plants and flowers – in those cases they also begin to show their photosynthetic characteristics faster even with a catastrophically small amount of water, light and pollen, although each flower in this hierarchy has its own maximum degree of such overcoming, after which the degradation of the structure begins.
