Effects of period and type of storage on germination test of Acacia polycantha seeds in South Kordofan State, Sudan

Abstract

The study aimed to investigate the effect of storage type and period of Acacia polycantha (Kakamout) on seeds germination and to attain an appropriate method of seed storage. The experiment was conducted at the Regional Tree Seed Centre-Elobied during the year 2016, and the seeds were collected from Kadugli site. Some tests were applied (purity, number of seeds/kg, moisture content, germination, viability) on seeds before and after their storage in three stores under different status (normal, cold and deep) and in four periods of time (3, 6, 9 and 12 months) for each sample. Experiment design by Randomized Complete Block Design (RCBD) with three replicates in storages by repeating three samples. The experiment used the Randomized Complete Block Design (RCBD) with three replicates in storages by repeating three samples. The data was analyzed by SAS software using ANOVA table, while LSD test used for means separation. The results showed a significant differences )α = 0.05 (in the normal store and high significant difference (p< 0.0001) in the deep store. Also, seeds revealed a decrease in the moisture content of the deep store by 4%, and a decrease in the number of seeds by11747 seeds for the cold store in the fourth period resulting in the weight gain of the seeds and the decrease in the number of seeds/kg. The study recommends the storage of Acacia polycantha seeds in deep, cool and normal storage at any period of the year.
