Architectural effects regulate resource allocation within the inflorescences with nonlinear blooming patterns

These data were generated to investigate the resource allocation pattern within the inflorescence of Salvia przewalskii, a perennial herb with 4-ouvle ovary flowers and flowering sequence-floral position decoupled inflorescences. Spatial and temporal resource allocations within inflorescences have been well-studied in many plants based on flowering sequence or floral position. However, there have been few attempts to investigate architectural effects and resource competition in species where the blooming pattern does not follow a linear positional pattern within the inflorescence. Moreover, most flowering plants show female-biased sex allocation in early or basal flowers, but it is unclear in species with inherent and changeless ovule production. The data demonstrated that pollen production and dry mass deceased from bottom to top flowers but didn’t significantly differ following flowering sequence, resulting in male-biased sex allocation in basal flowers. The seed production, fruit set...
