Factors affecting Nodule Formation in Legumes |
|
|
|
Introduction:
The growth of all organisms
depends on the availability of mineral nutrients, and none is more
important than nitrogen, which is required in large amounts as an
essential component of proteins, nucleic acids and other cellular
constituents. All legumes have the capacity
to fix their own nitrogen. Rhizobia bacteria combine with legume
roots to form nodules that, in turn, carry on nitrogen fixation – |
 |
the
process by which legume plants obtain (fix) the nitrogen they need from
the gaseous nitrogen in the air.

Project
description:
In this project, you will make use
of a soil bacterium of the genus Rhizobium
and a host legume to demonstrate the effects that soil microbes can
have on soil fertility and nutrient availability. |
