Phytotoxic Effect of Calligonum Polgonoides Extracts on Germination of Abelmoschus esculentus and Helianthus annuus

The present study was carried out to record and report the phtototoxic effect of Calligonium poygonoides Extract on Germination of Abelmoschus esculentus and Helianthus annuus. Calligonium is a Cushion shaped xeric shurby plant which is widely distributed throughout sandy xeric habitat of district Bannu Pakistan. This plant is restricted to certain area such as Domel. It is locally used for fuel and Naswar preparation. This plant has inhibitory effect on germination of radicle and plumule of seed. In this study the effect of different concentration ( 0 mg/ml, 5mg/ml, 7mg/ml, 10mg/ml) of shade dry leaf methanol extract of Calligonium polygonoides on germination of Abelmoschus esculentus and Helianthus annuus were investigated. The results showed that the methanol extract of this plant gradually decreased the germination percentage, especially at higher concentration. The radicle and plumule length were also affected by different concentration. Maximum growths were occurred at control Petri dish; the growth decreased as the concentration of extract increased; growth become Minimum at higher concentration. It is concluded that presence of Calligonum polygonoides in the field may retard the germination and seedling of Abelmoschus esculentus plants and Helianthus annuus.
