Inflorescence of Curcuma alismatifolia Gagnep.
Curcuma alismatifolia Gagnep.
The inflorescence is a terminal spicate thyrse, which is the key ornamental trait of the plant. Its morphological parameters, such as peduncle length and the number of bracts, determine the commercial value of the crop for cut flower or potted plant production.
In the reference 10 varieties crop Siam tulip, where this is mentioned in the description.
The inflorescence of Curcuma alismatifolia is described as a strobiliform spike. Key quantitative indicators include the length of the inflorescence, typically ranging from 10 to 25 cm, and the length of the peduncle, which ranges from 35 to 60 cm. An important evaluation parameter is also the total number of bracts, which are divided into fertile bracts and brightly colored coma bracts.
When evaluating ornamental quality, cultivation goals are taken into account: for cut flowers, long peduncles and large inflorescences are preferred, whereas for pot cultivars, breeding is aimed at compactness, where peduncles may be limited to 25 cm. Inflorescence morphology is highly dependent on light intensity and the light regime, the disruption of which leads to underdevelopment or excessive elongation of the peduncles.
The number of peduncles per plant serves as an indicator of cultivar productivity. The evaluation of inflorescence traits is carried out within the framework of variety trials according to DUS testing protocols, where parameters are recorded for genotype identification and the determination of the flower's commercial grade.
