Ranking of substrates based on Piptadenia gonoacantha morphological parameters

The definition of best substrates is often difficult due to variability of results observed in different measured variables. Therefore, we defined the best substrates for Piptadenia gonoacantha seedlings production through ranking, taking into account the relative importance of each variable in seed...
