Ученые объяснили как и зачем подсолнухи поворачиваются за солнцем

Ученые объяснили механизм и предназначение…

Оказалось, что способность поворачиваться под действием солнечного света (гелиотропизм) связана с согласованной работой светочувствительных механизмов и циркадианных ритмов растения и служат для интенсивного набора биомассы.

На первом этапе работы они искусственно фиксировали часть подопытных подсолнечников, не давая им следовать за Солнцем. Общая биомасса и площадь листьев таких растений оказалась в среднем на 10 процентов меньше, чем у росших без ограничений.

Тут нужно было както исключить влияние поддержки растения. Какое растение не фиксируй оно начинает дряхлеть и все питательные вещества уходят в цветы и плоды.
