Initiation and development of date palm inflorescences. (A) Undetermined axillary bud subtended by young leaves in the crown. (B) Inflorescence bud subtended by adult leaves before flowering. (C) Longitudinal section of inflorescence bud. (D) Young inflorescence bud shortly after rachilla and prophyll initiation. (E) Longitudinal section of young inflorescence bud. (F–K) Structure of young inflorescence after removal of prophyll rachilla. (F) Male inflorescence (around 10 mm in length). (G) Female inflorescence (around 10 mm in length). (H) Longitudinal section of the male rachilla. (I) Longitudinal section of the female rachilla. (J,K) Detail of cellular structures showing no starch accumulation in male rachilla (J) but high starch accumulation in female rachilla (K, starch bodies in pink). Abbreviations: A, apex; b, bract; Fm, floral meristem; Pa, parenchyma; Pe, peduncle of inflorescence; Pr, prophyll; Pv, provascular strand; R, rachis; Ra, rachillae.
