bloei

Bloei refers to the flowering phase in the life cycle of certain flowering plants, particularly those that exhibit a distinct change in growth pattern when transitioning from vegetative growth to the reproductive phase.

This phase is characterized by the emergence of reproductive structures, such as flowers, cones, or seed pods, which are typically produced on the stem tips of the plants. As the plants focus their energy on producing seeds, the growth rate often slows down, and the plant's appearance may change, reflecting the shift in energy allocation.

The bloei phase can be triggered by a range of internal and external factors, including changes in day length, temperature, and nutrient availability. Some plants, such as tulips and daffodils, enter a period of rapid growth after the onset of shorter daylight hours, while others, like daylilies, produce flowers in response to increased temperature.

Bloei can be divided into two distinct stages: the vegetative pre-bloom and the reproductive bloom phase. During the former, the plant continues to grow vegetatively, storing energy in the form of carbohydrates, which is then utilized during the bloei phase.

The bloei phase has significant implications for agriculture, horticulture, and plant breeding, as it can impact the timing and quantity of seed production, ultimately influencing crop yields and plant diversity.
