Cassava (Manihot esculenta Cruntz.) establishment depends on quality of planting materials. The experiment was done to determine the effects storage and variety on crop establishment and early growth vigour. Karembo and KME 4 varieties were stored in clamp under double shade (CUDS), horizontal under shade (HUS), vertical under shade (VUS) and horizontal under open ground (HOUG) as control for 16 weeks.

Planting materials was sampled from each storage methods after every 4 weeks and taken to field to evaluate their sprouting ability, number of primary shoots formation, number of leaves, rate of leaf formation and early growth vigour. Data were subjected to ANOVA and means separated by LSD. Sprouting percentage at Kabete was 54.73 % while in Kiboko had 37.78 %. The results showed that Kabete had 1.60 number of primary shoots per plant compared to 1.04 of Kiboko. The results showed KME4 had higher sprouting than Karembo in both sites. This can be due to genetic difference among varieties. The rate of leaf formation at Kiboko was higher as compared to Kabete it could be contribute difference in temperature between locations. Thus, optimum temperature and relative humidity should be factored in cassava cuttings storage to avoid increased death of stored cuttings. In case of storage cassava cuttings, should be stored in clamp under double shade methods under low temperature and moderate RH.

Tests of propagation of Pseudospondias microcarpa A. Rich. under the climatic conditions of Franceville in the southeastern of Gabon - JBES

Pseudospondias microcarpa A. Rich is a tropical tree species, which is not domesticated despite its food and pharmacological potentials. This study aims at introducing its domestication using two types of substrate. The first substrate (S1) is a mixture of compost and local soil while the second substrate (S2) is only made of local soil.

The goal is to determine the best method of propagating P. microcarpa, among the following three techniques: direct sowing of seeds, cutting and layering. For the direct sowing, seeds germinated in 41.67 % and 29.16 %, respectively in the substrates S1 and S2. Besides, the axillary and foliar growth of the plantlets was identical in both substrates. These results are due to the composition of the substrates and to the phenological stage occurring at the end of the observations.

Out of the 55 % of cuttings which recovered, all the plantlets withered then dried out. The insufficiency of the photosynthetic reserves and the lack of formation of calluses introducing the roots formation explain these phenomena. About 83 % of marcotts formed adventitious roots regardless the substrate, which explains a predisposition of the substrates in the induction of the roots formation. Of the three techniques tested, layering was found to be the best method of propagation of P. microcarpa.
