Growth of 7 species in the greenhouse receiving fish soluble nutrients (FSN) applied at weekly intervals was equivalent to plants fertilized with a nutrient solution derived from inorganic sources at equivalent rates of nitrogen.
Undergraduate interest in courses and curriculum in the agricultural sciences, including horticulture and plant and soil sciences (1), is at an all time high. Enrollment in agriculture in member institutions of the National Association of State Universities and Land-Grant Colleges more than doubled from 1963 to 19743. This paper describes changes that have been made in the Department of Plant and Soil Science at the University of Massachusetts to serve our students and provides a vehicle for future changes in undergraduate horticultural education. Hopefully, other departments will report on their undergraduate activities so that others may benefit from their experience.
The pansy, Viola tricolor Hortensis, L. is a popular bedding plant, however, the problem of low seed set has hindered genetic studies, plant breeding efforts, and the production of Fl hybrids. Twenty-nine commercial inbred pansy lines were investigated cytologically to establish a possible relationship between chromosome number and pollen fertility. The somatic chromosome number of all lines studied was found to be 2n=48 and pollen fertility was above 90 percent. Preliminary hybridization investigations suggest the problem may be an incompatibility system.
