“…It was also observed from this study that cold water treatment did not support the germination of Prosopis africana seeds. This is in agreement with the findings of Amoakoh et al [23] on Pouteria campachiana who reported that cold water treatment had a negative influence on the germination of Pouteria campachiana seeds. This study, furthermore, disagrees with the findings of Azad et al [24] who reported that hot water treatment had the highest germination on Acacia auriculiformis seeds.…”

Aims: The application of pre-sowing treatment has greatly improved the germination of seeds of tree species used in afforestation programmes all over the world. This study aimed to determine the effect of different pre-sowing treatments on the germination of Prosopis africana seeds. Study Design: The experiment was laid in a completely randomized design. Place and Duration of Study: This study was carried out from 11th November to 30th December 2019atthe Department of Forestry and Wildlife, Faculty of Agriculture, Nnamdi Azikiwe University, Awka, Anambra State, Nigeria. Methodology: Ten seeds each were soaked in ten treatments: tetraoxosulphate (VI) acid (H2SO4) for 10, 20 and 30 minutes; hot water for 6, 12 and 24 hours; and cold water for 3, 5 and 7 days. Ten seeds from each of the treatments were sown in a germination box containing sterilized river bank sand and each replicated five (5) times. Percentage germinations for each treatment were arcsine transformed, subjected to analysis of variance and significant means were separated using Duncan multiple range test at 5% probability level. Results: The results revealed significant differences (p<0.05) in germination. The seeds treated with acid for 30 minutes had the highest mean (51.405) and standard deviation (8.983), seeds soaked in cold water for 3 days and 7 days had no germination. Conclusion: The study concluded that soaking Prosopis africana seeds for 30 minutes in H2SO4 breaks its dormancy, hence, was recommended for improved seed germination.

“…Yisau et al [19] reported that the highest germination for mechanically scarified seeds of Albizia zygia was recorded on seeds scarified at the circumference, seeds of Acacia auriculiformis that were scarified at the micropyle, circumference, distal-end, and micropyle+distal-end resulted in the highest germination within shortest possible days. This agree with the report of Okunlola et al [20], Amoakoh et al, [21], and Osman et al (2004) that, faster germination of mechanically scarified seeds was noticed in Parkia biglobosa, Pouteria campachiana, and Lupinus varius as compared with other treatments employed. This suggests that dormancy resulting from impermeable seed coat (physical dormancy) may be overcome by peeling-off the seed coat [22].…”

This research was carried out to determine the effect of some pregermination treatments on the seeds of Acacia auriculiformis as it affects growth. The treatments involve the effect of sulphuric acid (concentration and time), mechanical scarification (at different sides), and hot water treatment (volume and time). Split plot design was used for acid treatment and hot water treatment, while Randomized Complete Block Design (RCBD) was used for mechanical scarification. The experiment was carried out at Federal University of Agriculture, Abeokuta, Nigeria. Parameters assessed include; plant height, stem height, leaf number. Acid treatment was carried out using different concentration of sulphuric acid (98%, 50% and 20%) and different treatment time (2 minutes, 5 minutes and 10 minutes). Concentration of acid was significant (p<0.05) on plant height, stem height and leaf number, higher concentration of acid (98%) enhanced morphological parameters of Acacia auriculiformis. Result showed that mechanical scarification significantly affect stem height (p<0.05), however, while mechanical scarification does not significantly affect plant height, the highest mean plant height (8.98 cm) was observed in seeds that were mechanically scarified at the micropyle; early germination of seeds was also noticed. Hot water treatment was carried out using different volume of water (50 cl and 1 litre) and varying treatment time (2 minutes, 4 minutes, 6 minutes and 10 minutes), the treatment showed no significant difference, and this method is not favourable for breaking seed dormancy of Acacia auriculiformis. Result showed that 100% germination could be achieved within seven (7) days when seeds are mechanically scarified at the micropyle, circumference, distal-end and micropyle+distalend, provided the seeds are viable. This research conclude that, acid scarification using H2SO4 at 98% concentration is the best method yielding better morphological parameters in Acacia auriculiformis, followed by mechanical scarification (especially when scarified at the micropyle).

“…The number of seeds germinated in each pre-treatment was recorded every two days. The germination percentage was calculated using the following equation at the end of the germination period (Amoakoh et al 2017): Germination percentage (GP) = (number of seeds germinated/number of planted seeds) × 100. The germination rate (GR) was calculated as the sum of the percentage of seed germination in each count by the time elapsed since the beginning of the test (Amoakoh et al 2017).…”

The germination rate (GR) was calculated as the sum of the percentage of seed germination in each count by the time elapsed since the beginning of the test (Amoakoh et al 2017). The mathematical expression of this criteria is expressed as GR= ∑ percentage of germination/days to the nal count.…”

Allium jesdianum is considered as the most important genera of the Liliaceae family with various pharmacological properties. The present study was carried out to determine the best pre-germination treatment in A. jesdianum. The highest seed germination (58.33%) was observed at chemical treatment including the combination of α-naphthaleneacetic acid (1 mgL− 1) and benzyl aminopurine (3 mgL− 1) on Murashige and Skoog (MS) media. The highest callus induction (86.7%) was observed at MS/2 media, which was supplemented by NAA (1 mgL− 1) and BAP (3 mgL− 1) from hypocotyl explants. Two elicitors including methyl jasmonate (MeJ) (0, 25, 50, and 100 µM) and putrescine (Pu) (0, 0.5, and 1 mM) were used to investigate their effects on lipid peroxidation, callus growth traits, total phenolics content (TPC), the contents of total flavonoids (TFD), total flavonols (TFL), anthocyanin, total chlorophyll, total carotenoids and on antioxidant activity through DPPH (1,1-diphenyl-2-picrylhydrazyl) method under callus culture. The results showed the superiority of MeJ over Pu for increasing the secondary metabolites and antioxidant activity in callused of A. Jesdianum, compared to the control. The highest TPC (6.02 mg GAEg− 1 FW), TFD (0.52 mg QEg− 1 FW), and TFL (0.39 mg QEg− 1 FW) were observed under 50 µM of MeJ. Meanwhile, the highest value for anthocyanin (8.99 µ mol g− 1 FW) was achieved at 25 µM of MeJ. The highest DPPH activities were observed at 50 and 100 µM of MeJ. Putrescine (0.5 mM) elicitation showed only superiority for callus growth rate (0.53 mm day− 1) and carotenoids (0.045 mg g− 1 DW). In this study, effective seed germination and elicitation of A. Jesdianum callus cultures were developed for the first time. Thus, new protocols could be suitable for future studies in biotechnological aspects of this medicinal plant.
