Variety traits
Rhubarb flower stalk
Rheum rhabarbarum L.
The rhubarb flower stalk is a generative organ reaching a height of 2–2.5 m, which depletes the plant and reduces the market quality of the petioles. Regular removal of flower stalks is an essential agrotechnical practice to maintain crop productivity.
In the reference 6 varieties crop Rhubarb, where this is mentioned in the description.
In rhubarb breeding, the flower stalk is an important subject during DUS testing. Varieties are evaluated based on the intensity of flowering, the height of the panicle, and the density of the inflorescence, which are measured on a representative sample of plants during their full development stage.
The growth of the flower stalk requires significant nutrient resources, which leads to a redistribution of energy to the detriment of vegetative mass. The development of generative organs causes the leaves to become smaller and reduces the juiciness of the petioles, and during the active flowering phase, the taste quality of the produce deteriorates.
To ensure stable yields, flower stalks must be removed promptly at their very base. Neglecting this practice leads to the repeated formation of seed stalks throughout the summer period, which negatively affects the total mass and market characteristics of the crop.
