Studies On Seed Germination Physiology Germinant Establishment And Seedling Growth Performance Of Ficus Sur Forssk. (moraceae)

Ficus sur is a fig tree that belongs to the genus Ficus family Moraceae and order Rosales. It grows at altitudinal ranges 1400-2500 m.a.s.l. Seed production, germination physiology, germinant establishment and seedling growth performance studies were conducted in Addis Ababa University, College of Life Sciences. Seed pretreatments were achieved using 100 μM, 10 μM, 1μM and 0.1μM concentrations of gibberellic acid (GA3) and potassium nitrate (KNO3) separately. Plant-derived aqueous smoke extract solutions at relative concentrations of 25%, 50%, 75% and 100% were also used to pretreat seeds and stimulate germination. The control was to treat seeds with double distilled water. Petri dishes were randomly arranged under a light source from one Phillips fluorescent tube set at a height of 50 cm and producing light at a rate of ca. 40 μmol m-2 s-1. Temperature and relative humidity of the room were 26.55 ± 2.650 C and 44.15 ± 6.25%, respectively. Stereomicroscope examination of seeds was indicated 57.3% of the seeds were damaged and the balance 42.7 % was health. Significant (P
