Here is the first book to treat the control of sexuality in plants. The authors provide a thorough review of the literature and discuss many new findings from their laboratory. They include a review of the evolution and genetics of sexuality, including new data on the effect of primary environmental factors on sex expression and the influence of phytohormones on the expression of sexuality as a function of age. The work discussed here has significant implications for plant breeding. Agronomists, horticulturists, and plant physiologists will find practical information on procedures to use in the field or the green house, as well as a thorough introduction to the principles of flowering and fruiting.Here is the first book to treat the control of sexuality in plants.
