ABSTRACT

This chapter seeks to isolate specific studies showing the varied influences on flower and inflorescence development. M. Kh. Chailakhyan and associates and M. J. Viana found that removal of the root system in Bryophyllum daigremontianum has a slight promotive effect on the rate of inflorescence development with no apparent effect upon inflorescence structure. Several studies suggest that the apical bud controls development of axillary flowers or inflorescences in the same fashion that it controls development of axillary shoots. The greater the number of axillary shoots competing with the reproductive structures the greater the impact on development. The chapter explores the morphogenetic features within the reproductive meristems. Three types of reproductive primordia have mainly been investigated: young inflorescences, flower buds, and floral organs. The normal sequence of initiation of all floral organs generally occurs in young flower buds excised at the sepal or sepal plus petal primordium stage.
