Allelopathic Effect of Calotropis procera, Hyoscyamus muticus and Pulicaria undulata Extracts on Seed Germination of Portulaca oleracea and Chenopodium murale

Nadi Awad Al-Harbi

Abstract:
Background and Objective: The use of herbicides leads to severe damage, especially to the environment. The aim of this investigation was operated to study the allelopathic effect of Calotropis procera, Hyoscyamus muticus and Pulicaria undulata aqueous extracts on the seed germination of Portulaca oleracea and Chenopodium murale. Materials and Methods: The aerial parts of the plants (Calotropis procera, Hyoscyamus muticus and Pulicaria undulata) washed well in distilled water and were dried in room temperature then ground to fine powder. Aqueous extract was prepared using distilled water. Results: In this study, different concentrations of plant extracts (1, 3 and 5%) were used to illustrate which of these concentrations have the potential to inhibit seed growth of Portulaca oleracea and Chenopodium murale. Concentration of 5% for all plant extracts used to inhibited the growth of all seeds of Chenopodium murale while, concentration of 5% for Pulicaria undulata extract only inhibited the growth of all seeds of Portulaca oleracea. Conclusion: This work dealt with the use of allelopathy strategy in preventing the growth of some weeds to be one of the safest alternative ways of using herbicides. The results showed the effective effect of plant extracts for both Calotropis procera, Hyoscyamus muticus and Pulicaria undulata on the seed germination of Portulaca oleracea and Chenopodium murale.
