A.             Storage Unit:

The well-preservation of seeds; it preserves the vitality of seeds and secures that they are not subjected to damage by the many factors, such as, the conditions of the seeds, temperature, humidity, and pest infections. It is the unit in which seeds are stored within suitable and adequate conditions, and it involves:

-    Storage in room-temperature conditions 25° (short-term storage).

-   Storage in 4° conditions (medium-term storage)

-    Storage in  -20° conditions (long-term storage).

         

B.              Registration Unit

This unit deals with receiving seeds from diverse sources (farmers, organizations…etc). As soon as they are received, a form is filled which contains all the required details about these seeds; source, location, place, time of planting, time of harvest, total weight. They are then transferred to the processing unit where they are cleaned, sanitized, and screened and then packed. In addition, a sample will be sent to the lab so as the required tests are run on the sample.

 

C.             Drying Unit

After receiving the sample, its humidity rate is measured in order to dry the seeds in this unit in case the sample showed that the humidity ratio is higher than average. The unit also works on received fruits, where seeds are extracted from these fruits in the lab, and are later put to dry. The drying process occurs in special conditions, where it is best done at 25°, and with a humidity percentage of 10-15%. However, each brand requires a special drying temperature.

D.             Data-Base Unit

All data collected about the seeds in the registration unit, in addition to photographs, are entered in the Seeds Bank data base. The aim of this unit is to preserve the special data of each brand in terms of its original traits. This helps control and stops the deterioration and loss of the seeds. After entering all the available data, each entry is given a unique code which is directly related to the information about the brand. This facilitates the working procedures of the seeds bank and eases dealing with all the entered information. The entries are identified by their local Arabic names and English names, as well as their scientific names and scientific categorization. Any experiments done on any entry is also documented in the data base.

E.              Distribution Unit

It is the unit which deals with those interested in benefiting from the local community seeds bank. These can be farmers, students, researchers, or other interested individuals and organizations. The distribution process is thus under inspection and related to the available quantities of seeds which are meant to be distributed in the Seeds Bank.

F.              Reproduction Unit

It is the unit dealing with reproducing seeds, each brand in accordance with its special method. This is done by planting seeds in several locations which are environmentally different, in such quantities which can provide the Seeds Bank with the required quantities of seeds, especially in case of seeds found in small quantities. It also deals with producing larger quantities of the brands meant to be distributed.

 

G.     Laboratory Unit

It consists of a laboratory which is equipped with the required devices needed to test the seeds in the seeds bank after the reception, cleansing, selection, and data entering of the seeds.

 

Several tests are performed on the samples after their registration such as:

§     Germination test.

§     Vigorous test.

§     Purity ratio.

§     Dry matter percent.

§     Moisture percent.
