Malcolm Morrison, crop physiologist, Agriculture and Agri-Food Canada

Malcolm Morrison is a crop physiologist at Agriculture and Agri-Food Canada’s (AAFC) Ottawa Research and Development Centre. He holds a bachelor’s degree in agronomy from Macdonald College (part of McGill University), a master’s in plant breeding from the University of Saskatchewan and a PhD in canola physiology from the University of Manitoba (U of M). His career has focused on finding traits for resistance to abiotic stresses such as cold, heat and moisture stress. 

Morrison lives in Ottawa, ON, with his wife and their Australian Shepard. Their two adult children live nearby and visit weekly.

Where did you work before AAFC?

Before joining AAFC, I had different summer jobs, including working in southern Ontario for King Grain. After completing my master’s, I applied for a position with AAFC and was hired as a biologist. I did a PhD at U of M in canola physiology with Peter McVetty and began working as a research scientist in Ottawa in 1988.

What got you interested in this area of work?

I have always been interested in how crops grow, become efficient and handle stress – factors that affect the transition from one seed to many. In my first-year botany class, the professor described a seed as “a baby plant carrying its lunch,” and that idea stuck with me.

My work has been focused on increasing the number of “baby plants” and analyzing or improving their “lunch,” whether oil, protein or nutritional and antinutritional compounds. We studied soybean protein across Western Canada, for example, examining how efficiently crops take up nitrogen and store it in their seeds. Understanding and improving the way a crop collects, utilizes and stores things such as solar radiation, moisture and nutrients has been a major focus throughout my career.

Tell us a bit about what you’re working on at AAFC.

Currently, I work with two great technicians, Claire and Tom, and we start each day with a brief meeting to plan out the day or week. I work on emails and focus on reports and analyzing data from projects. We have experiments on the go year-round at various stages from start to finish, either in fields or growth cabinets.

One example is the “Getting the jump on spring corn growth” project, funded partially by Manitoba Crop Alliance. This project began in 2023 and builds on years of work we’ve done since 2014 on improving early growth cold tolerance in corn. There are three main objectives of this research: to validate our previous results with a new set of hybrids, to broaden our understanding of plant performance beyond initial emergence and to conduct field tests in Manitoba and Ontario to determine whether early germination leads to faster seedling and plant growth.

Initial findings demonstrate a connection between faster emergence and enhanced root development in colder temperatures. Some hybrid corn lines emerged up to five days earlier than the checks, with improved root growth at lower temperatures, too. In warm temperatures, differences between hybrids disappeared. Initial field trials in Ottawa in 2024 indicate that hybrids seeded early on May 6 reached maturity by Sept. 18.

What can you say about the value of farmers providing funding and support to your work?

I’m a big proponent of check-off funds going towards research objectives established by farmers. These funds enable researchers to address specific challenges identified by grower organizations. Farmer-driven priorities ensure our research solves real-world problems.
