How Digging Into Root Science Can Help Crops Grow in Dry Conditions

The importance of roots in plant growth is often overlooked or misunderstood. However, rice roots have a distinct anatomy and architecture, making them fascinating to study. Dr. Amelia Henry, Senior Scientist II at the International Rice Research Institute (IRRI), and her team are helping shed light on the understudied science of roots, particularly in rice.

Her work has been recognized for this year’s Dundee Root Medal, given by the International Society of Root Research (ISRR) for her “outstanding contribution to the field of root research."

Dr. Henry also delivered the Dundee Medal Lecture “Integrated root phenotypes for dry direct-seeded rice.” In her lecture, she emphasized the range of root trait combinations characterized under direct seeding in the IRRI elite breeding pool and the large variation in root and shoot growth observed across partner sites.

A long legacy of root research at IRRI

Although IRRI is well known for its key role in the Green Revolution, its Genebank, or the novel crop management techniques it has developed, there is also a long legacy of root research at IRRI. For decades, the International Rice Research Institute (IRRI) has studied how rice roots can help crops survive and thrive in dry conditions. In the 1960s, scientists focused on how different root structures might help rice plants access more water from the soil during drought. By the mid-1970s, IRRI researchers applied different methods to measure root growth and how they could grow deep to reach underground water sources. They even created tools to "pull" roots, measuring their strength to understand how well they could withstand drought.

In the 1980s, scientists at IRRI grew plants with their roots exposed to air (aeroponic techniques) to closely examine root shapes and structures, while field studies helped show how roots grow in real-world conditions.

Sunflowers at Gordon Skagit Farms

Video: Sunflowers at Gordon Skagit Farms

Last year we had the chance to tour the 8-acre sunflower field at Gordon Skagit Farms and today I thought it would be fun to share some of the footage we filmed with you. If you’re within driving distance of the Skagit Valley and are looking for something to do this weekend, Gordon Skagit is open through the end of the month. In addition to having more specialty squash, pumpkins, and gourds than you can imagine, you will also be able to see this amazing sunflower field in its full glory.
