DEPARTMENT OF PLANT PHYSIOLOGY 



At the close of the period covered by this report, Professor B. M. 

 Duggar, head of the Department, resigned to accept a position as Research 

 Professor of Botany in the jMissouri Botanical Garden at St. Louis. The 

 Department of Plant Physiology was established by Professor Duggar. 

 Through his tireless energy, zeal, and inspiration the Department de- 

 veloped to a high degree of efificiency. His reputation in botanical science 

 gave prestige to the Department and attracted to it a large number of 

 graduate students from different institutions. His sympathy, his counsel, 

 and the stimulus that he gave to research, as well as his teaching, will be 

 greatly missed. 



TEACHING 



During the past year the teaching division of the work has been placed 

 on a more efficient basis. The increase in laboratory space by the 

 acquisition of the farm mechanics laboratory made possible better 

 laboratory teaching. For the first four weeks of the first semester, how- 

 ever, the students and staff were considerably handicapped by the delay 

 in equipping the newly acquired laboratory. 



The enrollment of students in the Department during the past year 

 has shown a considerable increase over that of the previous year. This 

 is due in part to a normal growth and also to the acquisition of increased 

 laboratory space, making possible the accommodation of lOO students in 

 Course 7, which, during the previous year, was limited to 50 registrations. 

 Ten courses were given during the past year, with a total registration of 

 262 students. Credit hours of instruction given in the courses totaled 

 756. Of graduate students there were 28, of whom 7 were major students 

 for the degree of Ph.D. and one was a major for the M.S. A. Not all 

 these graduate students in the Department were engaged in research 

 work, but it may be conservatively estimated that the equivalent of 160 

 credit hours for each semester was spent by graduate students in research 

 work. 



In the following table is presented a summary of the teaching work 

 of the Department since the year of its organization:
