 The Departments of Environmental Horticulture and
Horticultural Sciences offer a joint program in horticultural
science leading to the Master of Agriculture, Master of
Science, and Doctor of Philosophy degrees, with special-
ization in fruit crops, environmental horticulture, or veg-
etable crops.
 Areas of emphasis include crop physiology and bio-
chemistry, seed physiology, crop breeding and genetics,
environmental science, crop production and management,
landscape horticulture, postharvest physiology, biochem-
istry, and handling and horticultural taxonomy.
 New graduate students should have undergraduate train-
ing in horticulture or plant science which should include
credits in fruit crops, environmental horticulture, vegetable
crops, or general horticulture and botany, mathematics,
chemistry, soils, entomology, and plant pathologyor equiva-
lent. Student interest and available guidance and facilities
will determine the area of emphasis within a given special-
ization for the thesis or dissertation problem. It is possible to
conduct certain types of research for the Master of Science
and Doctor of Philosophy degrees at one of the Agricultural
Research and Education Centers of the Institute of Food and
Agricultural Sciences.
