An Investigation of the Allelopathic Effects of Atriplex canescens (James) on Seed Germination in Artemisia sieberi (Sesser)

The allelopathtic effects of Atriplex canescens on seed germination in Artemisia sieberi was investigated through the present study. Since there was not enough knowledge on allelopathic effects of A. canescens on A. sieberi, thus allelopathic effects were first studied using solid MS medium. Then the allelopathic effects were studied using At. canescens extracts on Ar. sieberi seed germination in a germinator. Therefore, a ten percent weight/volume (W/V) extract from leaves and fruits of A. canescens was prepared. The extract was diluted by adding distilled water to 5, 10, 15, 20 and 25 percent. The effects of the above concentrations, as well as distilled water as control, were studied on seed germination using a completely randomized design (CRD). The treatments were grouped using Duncan test. Results indicated that there were significant differences among the treatments for either germination speed or germination rate (P<1%). Control and the 5% concentration exhibited the highest germination value while 25% lead to the lowest percentages germination.
