Biometric study was done on six biotypes of sea buckthorn from Romania (three of three of spontaneous vegetation and culture). We have analyzed the morphological features of pseudofruits following: length, diameter and their individual biomass. Observed values were statistically processed. Biotypes Letea 6 (of spontaneous vegetation) and Delta 60M (over the culture) proved superior in pseudofruit size and biomass. Pseudofruit length and diameter are parameters with low variability, and mass presents medium to small variability.
