What is the aestivation in tomato flower?

Aestivation in tomato flowers refers to the arrangement of the flower parts, particularly the petals and sepals, before the flower opens. In tomato, the petals are typically folded back against each other in a bud, which is a characteristic form of aestivation known as "valvate" aestivation. This arrangement helps protect the reproductive structures inside the bud until the flower is ready to bloom. Understanding aestivation is important for breeding and cultivation as it can influence pollination and fruit set.
