“…Seeds treated with hot water failed to germinate irrespective of the duration of the treatment. This result is similar to that reported with Enantia chlorantha (Gbadamosi and Oni, 2004) and Tamarindus indica (Fandohan et al, 2010), but contrasts with those reported with many species including Robinia pseudoacacia (Mirzaei et al, 2013). This indicates that there exist some interspecies variation in the response of dormant seeds to various seed dormancy breakers, but the determinism of these variations is not well known.…”

Despite its socioeconomic importance, the cultivation of Xylopia aethiopica is not popular owing to the difficulty in seed germination. As a step in its domestication process, investigations were undertaken on germination requirements and desiccation tolerance of seeds. Three substrates (forest top soil, river sand and a mixture of forest top soil and river sand) and 18 pre-germination treatments including a control (untreated seeds), a mechanical scarification, six heat treatments which were done by soaking seeds in hot water (100 °C) for different lengths of time, and ten acid scarifications which were done by soaking seeds in either sulfuric acid or hydrochloric acid for different lengths of time were tested for their effect on seed germination. Results showed that mean percentage germination was higher on the mixture of forest top soil and river sand (29.4 ± 2.6%) than on other substrates tested. While untreated seeds and those soaked in hot water irrespective of the duration of treatment failed to germinate, seed dormancy was successfully broken by either mechanical or chemical scarification. Soaking seeds in either concentrated HCl or concentrated H 2 SO 2 for 5 min were the most effective treatments in breaking dormancy, with 80 ± 6.3% and 70 ± 6.3% mean germination recorded respectively. The desiccation tolerance test showed that X. aethiopica seeds are desiccation-tolerant and their storage behaviour is orthodox. This study shows that for propagating X. aethiopica from seeds, it is recommended that fresh or dried seeds be soaked in either concentrated HCl or concentrated H 2 SO 4 for 5 min, and that seeding be done in substrate composed of a mixture of forest top soil and river sand in a 1:1 (v/v) ratio.

“…Determination of the height of the first basal branching helps to identify low branching individuals for which fruit harvesting will be less painful. Such accessions are then so necessary for selection programs and breeding for fruit production [34]. The variability obtained for this parameter in the current study is then a good indicator of plant breeding for this character.…”

Chrysophyllum albidum is a tropical forest species which plays tremendous socioeconomic role in west Africa because of its fruits large comsuption and trade. Morphological variation and ecological structure of Chrysophyllum albidum G. Don were assessed in Benin in order to contribute to the species domestication. Dendrometric parameters such as diameter at breast height, total height, and bole heigt were measures from 120 individual trees across two ecological zones and four different provenances. In addition, morphometric parameter related to fruits and seeds such as fruit length, fruit width, fruit weigh, seed length, seed width and seed weigh were measured for 1,800 fruits and 1,800 seeds. Principal component analysis was performed on the untransformed morphometric data using the correlation matrix. Diameter and height classes distribution of C. albidum in each ecological zone adjusted to Weibull distribution showed a bell shaped curve with left dissymmetry, characteristic of young stands (form coefficient between 1 and 3.6). From principal component analysis, no differentiation was observed, indicating that accessions from different agroecological zones were similar

“…Germination was allowed to proceed for 50 days after which the experiment was termination. A seed was considered to have germinated when the hypocotyls hook is evident above the soil surface (Fandohan et al 2010). Data collected on germination was used to calculate germination percentage GP, mean germination time (MGT) and germination index (GI) for each treatment using the equation below.…”

A nursery experiment was conducted to determine the effects of seed pretreatment methods on the germination of Faidherbia albida at ICRAF, Nairobi from six provenances consisting of Awassa, Taveta, Lake Koka, Maseno, Chinzombo and Wagingombe. Seeds were subjected to five pretreatment methods namely nicking, soaking in acid, hot water, cold water and control. Germination percentages (GP), mean germination time (MGT) and germination index (GI) were calculated and the data was subjected to ANOVA. The study revealed significant (p B 0.05) differences in seed treatments among provenances in all studied parameters. Highest germination among pretreatments in Awassa (99 %) and Wagingombe (80 %) was observed in nicked seeds, Chinzombo (81 %) in nicked and acid treated seeds, Lake Koka (90 %) in acid treated seeds and Taveta (28 %) and Maseno (64 %) in cold water treated seeds. Nicking gave the highest cumulative GP (69.67) while lowest GP was observed in hot water treated seeds (23.17). Acid treatment exhibited lowest MGT (8.85 days) and highest GI (2.29) while highest MGT (24.35 days) and lowest GI (0.31) were observed in control and hot water treatment respectively. Although acid treatment gave a high GP and lowest MGT and GI, nicking and soaking in cold water for 24 h is being recommended as cheaper and less hazardous pretreatment methods to improve germination in F. albida since sulphuric acid is expensive and requires proper handling techniques. Significant correlation between geo-climatic data and germination parameters of seeds subjected to different pretreatments indicates that provenances are as important as pretreatments in germination of the species.
