Wind wheel:

Click on the wind wheel to change the direction and intensity of the wind.
Correspondence with the Beaufort wind scale:
Calm : 0 BF
Light Breeze : 2 BF
Moderate Breeze : 4 BF
Strong Breeze : 6 BF
Wind direction and intensity correspond to the average values recorded during the period in which there is flowering coincidence. Importantly, only the daily hours in which maize pollen is released from masculine flowers have to be considered in averaging the wind date (usually from mid-morning to early evening). Also note that there is no significant pollen dispersal in rainy days.

The canvas shows the fields under study, colored in accordance with their type of culture (conventional, transgenic or others).
Note that the color of conventional fields depends on the estimated GM content.

Transgenic to conventional field interaction

Detailed information on the interaction between two specific fields.
The following 4 factors are considered to estimate the GMO contents of a particular conventional field occurring as a consequence of pollen from a particular transgenic field:

  • - Flowering coincidence (number of days in which masculine flowers in the donor field and feminine flowers in the receptor field are fertile), and physical distance between the fields (in m) serve to calculate the Global Index published in Messeguer et al., 2006. These two factors, together with the wind direction and intensity, were used to estimate GM contents of conventional fields in the first version of the program (GIMI 1.0).
  • - This new version, GIMI 2.0, additionally considers the vulnerability index, which depends on the shape and size of the two fields (transgenic and conventional) (Melé et al., 2013).
  • The predicted GM content in the receptor field due to this specific interaction corresponds to the product of these 4 values.
