Bud — Regal Pelargonium

Pelargonium grandiflorum (Andrews) Willd.

The bud of the regal pelargonium serves as a biological marker of readiness for flowering and an indicator of the agrotechnical regime required for inflorescence formation.

In the reference 6 varieties crop Regal pelargonium, where this is mentioned in the description.

The appearance of buds in regal pelargonium is a critical phase of the life cycle, the transition to which directly depends on maintaining a period of cool dormancy at 10–14 °C for 6–10 weeks and providing intensive lighting. The absence of buds in the spring is the primary sign of improper plant growing conditions.

In agronomic practice, the state of the buds is used as a signal to adjust the fertilization regime, including a switch to phosphorus fertilizers. On young cuttings, it is standard practice to remove early buds to redirect the plant's resources from generative development to the formation of the root system and vegetative mass.

Although the bud is not a standardized morphometric trait with quantitative units of measurement, it is significant for the ornamental assessment of a variety, where the shape and color of the petals are considered prior to the full opening of the flower.
