Comparative study of oil palm seedlings morphological development of from three stages of germinated seed differentiation

The oil palm pre-nursery corresponds to the cultivation of young plants during the four (4) months following seed germination. Before transplanting, the pre-germinated seeds were subjected to quality control. The control made it possible to eliminate anomalous or undifferentiated sprouted seeds by using well-defined sorting criteria. Nevertheless, these criteria are sometimes poorly known to the sorting operator and provide oil palm producers with seeds with insufficient development to allow transplantation, leading to a low emergence percentage in the pre-nursery.This study evaluated the morphological development of oil palm (Elaeis guineensis Jacq. 1760) obtained from the three (3) stages of differentiation of sprouted seed differentiation. These were long differentiated seeds (DL), medium differentiated seeds (MD), and undifferentiated seeds (ND). Of this study, it appears that undifferentiated seeds (ND) and medium differentiated seeds (MD) recorded the highest number of dead seedlings with 111.00 ± 10.13 and 102.75 ± 38.93 dead seedlings, respectively. The long-differentiated seeds (DL) have given Seedlings longer and higher fresh weight with 43.55 ± 9.34 cm and 25.05 ± 11.18 g, respectively. The moderately differentiated (MD) seeds produced seedlings with a crown diameter of 0.75 ± 0.32 cm, larger and a root system 26.17 ± 7.75 cm more developed than the undifferentiated and long differentiated seeds. However, no difference was observed between the number of leaves emitted from the seedlings and the root system with regard to the three (3) stages of differentiation of the sprouted seeds.
