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. |
