Length of Early Maturation Period Determines Flower Number and Yield

Caption

These five members of the solenaceae family are morphologically very similar in the earliest stages of maturation (far left column). Key changes in gene expression, occurring in each plant as it moves from a vegetative state to a reproductive one, accounts for the complexity of its inflorescence architecture and the number of flowers it produces. Most of these changes take place in the second column from the left, labeled TM (transition meristem). The column labeled FM (floral meristem) marks the number of days after germination (DAG) when the growth that will become the first flower appears. The more protracted the maturation, the longer it takes for flowers to appear and the more flowers will ultimately be generated.
