this study investigated the effects of different concentrations of leaf extracts from native (P. cineraria) and non-native (P. Juliflora) Prosopis species on the germination and early growth of Taverniera spartea under laboratory conditions.
Thirty healthy mother plants of T. spartea were randomly selected from the forest floor vegetation in Sirik County. Following seed collection and viability assessment, 15 seeds per treatment, with four replications, were placed in Petri dishes lined with filter paper moistened with leaf extract solutions at concentrations of 0, 2, 4, 6, and 8%. The measured variables included germination percentage, radicle length, and plumule length. Data were analyzed using a General Linear Model (GLM).
The results indicated that the greatest plumule lengths occurred in the control (2.68 cm) and 4% (2.33 cm) treatments, while the highest germination percentage was observed at the 6% concentration (15.83%) (p < 0.05). Furthermore, the native Prosopis treatment yielded higher values for germination percentage (17%), radicle length (2.83 cm), and plumule length (2.43 cm) compared to the non-native Prosopis. The interaction analysis revealed that the leaf extract of the native Prosopis species, particularly at moderate concentrations (4 and 6%), enhanced both germination and early seedling growth of T. spartea. In contrast, the non-native Prosopis species exhibited inhibitory effects. The differences in inhibitory compound concentrations and the higher ecological compatibility of local fauna and flora with the native species P. cineraria may explain the contrasting allelopathic effects observed between the two Prosopis species..
