Abstract
The development of shoot apices of cauliflower plants grown under inductive and non-inductive temperatures for flowering was studied. Two cultivars were used, Snowball M and February-Early-March. Neither cultivar flowers without a period of growth at 42 F. February-Early-March requires a cold treatment for curd formation. During the first 5 weeks of growth, shoot apices of vegetative Snowball M plants have five distinct zones: a mantle, central-mother cells, cambial-like cells, peripheral cells, and rib meristem. Curd initiation is marked by a wide shoot apex, lack of cambial-like cell zone, and the initiation of bracts and branch primordia. Under non-inductive conditions for flowering, apices of February-Early-March are similar in their zonation to those of Snowball M before curd initiation. During growth at 42 F, apices of both cultivars have large nuclei and nucleoli and dense cytoplasm. Curd initiation occurs during or following the cold treatment in Snowball M, while in February-Early-...
