Commercial beans (Phaseolus vulgaris L.) were submitted to silanization treatments aiming at the formation of hydrophobic films. The hexamethyldisilazane (HDMS) was the precursor reagent for all treatments. The results indicate that all sequence generate hydrophobic surface on the crops, reducing the relative absorbed humidity in the range of 15 to 57% when compared to non-treated samples. Standard germination tests showed that the treatments delay or avoid undesirable germination, even in high humidity environment.
