What is the Issue? |
| FOREST PRODUCTIVITY AND HEALTH |
|
It has long been known that tissues of healthy plants can be colonized internally by microorganisms. Work with plant species indicates that some endophytic bacterial strains may act as protective agents and help to stimulate host plant growth by acting as biocontrol agents. In contrast to agricultural crop species, almost nothing is known about bacterial endophytes of trees. This study is examining the effect of bacterial endophytes on tree growth and nitrogen-fixing activity within lodgepole pine ecotypes. Results from the study will provide understanding of the symbiotic relationship between trees and bacterial endophytes and help to inform on possible future practical applications in forestry.

What is our goal? |
| UNDERSTANDING MECHANISMS OF TREE GROWTH AND PRODUCTIVITY.
|
| Do plant growth-promoting or nitrogen fixing bacterial endophytes live in Lodgepole Pine? |
Where we currently stand. |
| Fieldwork began in January 2000. Samples of lodgepole pine seedlings, stems and needles were collected. In the laboratory, endophytic bacteria were isolated from internal plant tissues. Analyses are currently underway to determine whether these microorganisms are capable of fixing nitrogen inside seedling tissues and thereby affecting seedling performance. The study is expected to run until July, 2001. Results are expected next year and will be published.
