The direction of sunflowers visibly affects their productivity and how healthy they are. some sunflowers always looking east some of them return to whichever side the sun is on. Those facing east benefit greatly from these ‘choices’ and are healthier.
This behavior of always facing east, is mostly observed in older sunflowers. Young people, on the other hand, come true wherever the sun goes. So why is it better for them to turn east? Also, why do old sunflowers get this habit? Let’s answer these questions with the information provided by a recent study.
Morning sun makes sunflowers grow faster
A long-term research to find the answer to the above questions has recently yielded results. According to the information obtained, facing east in the morning and getting the morning sun, sunflowers makes it more attractive to pollinators. Sunflowers, which attract more bees in the morning, both grow better and start pollen production earlier; It also becomes more efficient in general. At different times of the day, the bees do not choose by being influenced by the side the sunflowers are facing. In other words, there is no loss of east-facing sunflowers for the rest of the day.
“But when the sun is almost in that direction, can’t the sunflowers turn into the morning sun too?” you can ask. The answer is easy: because sunflowers are not animals, they cannot return to the direction of the sun in a few seconds. as the sun goes down young sunflowers facing west until morning, they lag behind the old sunflowers in the time it takes to return to that direction when the sun rises. The fact that the interest of the bees in the young sunflowers, which are heated artificially within the scope of the research, does not increase, repeats the importance of the morning sun. However, the difference between artificial sun and natural sun while providing this function is still unknown.
So why do old sunflowers ‘choose’ to always face east?
sunflowers the stems get tougher as they get older. This makes it difficult for sunflowers to return to the sun over time. When this move gets pretty tough, the older sunflowers decide to fix the flower heads facing east. The difference in the productivity and development of sunflowers, which were turned westward by the researchers, reaffirms the advantage of facing east. As a result, sunflowers stubbornly facing east; it has larger seeds, is healthier, produces earlier and more pollen.
