Professor of Citrus ScienceProgram CoordinatorJohn and Ruth Tyndall Chair in Citrus Sciences
I like to work closely with my students, from a scientific research point of view. Define a problem, design a method of coming up with the answer to the problem, and then actually do the research to find the answers. I think it is important to instill the sense of curiosity and joy and wonder about what we do.

Dr. Manners attended Anderson College, earning the B. A. in chemistry and biology. From there, he went to the University of Florida for the M. S. and Ph. D. degrees in horticultural science, specializing in flowering physiology of tropical fruits. He has been teaching at FSC since 1981, and has specialized in fruit production (mostly citrus), as well as roses, and techniques of propagation of various crops. Since 1996, he has participated in 14 USAID-funded volunteer consulting missions to developing countries, to help alleviate their extreme poverty through education on better crop production methods. Countries include Ethiopia, Egypt, Armenia, Turkmenistan, Kyrgyzstan, India, Bangladesh, Mozambique, Nigeria, and Angola. He is very active in the preservation of heirloom genetic resources in roses, and is a trustee of the Heritage Rose Foundation.
