title: My favourite flowering image: Maryland Mammoth tobacco.
abstract: Almost 100 years ago, the study of Maryland Mammoth tobacco by Garner and Allard was one in a long series of studies that have led to a better understanding of how plants "decide" when to flower. deciphering how plants "decide" when to flower. The extreme phenotype of Maryland Mammoth tobacco, in which a single recessive mutation changes a day-neutral to a strictly photoperiod-requiring plant, impressively illustrates the action of the photoperiodic pathway of flowering.
