ALLELOCHEMICAL EFFECTS OF TAMARIX APHYLLA L.
Farrukh Hussain
Abstract
Abstract Tamarix aphylla L is a medium size tree growing in the plains of Pakistan. Aqueous extracts from leaves, stems and stem-bark were obtained by soaking 10 g dried powdered material of each part in 100 ml distilled water at 25 °C for 24 hrs; and filtered. Three concentrations were tested against Triticum aestivum, Avena sativa and Allium cepa in laboratory. The results indicated that all the extracts reduced the germination and various growth parameters to different degrees among the test species and plant parts. The extracts significantly reduced mitotic cell division and development of root tip cells of test species. The allelopathic effects depended on part assayed, concentration of extract and growth parameters measured. Germination and plumule growth was less sensitive than radicle growth. It is suggested that Tamarix aphylla is strongly allelopathic, which can be a candidate as natural herbicide for controlling weeds and can play role as antimicrobial agent.
