ABSTRACT
This chapter is devoted to Sinapis alba, which is by far the mustard best known to physiologists. Sinapis, like other members of the Cruciferae family, is more sensitive to blue light than to any other spectral regions. Sinapis alba has the properties of a mild mustard. Besides its use for condiment preparation, it is also grown as green manure or less often as a fodder plant. Removal of 2 young leaves promoted flower initiation in plants subjected to a minimal inductive treatment. In order to gain insight into the nature of biochemical processes occurring in the shoot apex of plants induced to flower by one long days (LD), different metabolic inhibitors were administered to the terminal bud at various times after the start of the inductive LD. Shoot tips excised from soaked seeds and grown on agar medium with complete nutrients solution could regenerate an entire plant.
