Study of Allelopathic Properties of Saffron Fields and Methods of Its Ameliorate

Document Type : Research Article




Introduction: The allelopathic potential of saffron in three experiments were investigated.

Materials and Methods: In this study, we examined the aqueous and aqueous methanol extract of saffron (Crocus sativus L.), 9-year-saffron cultivated soils and non-saffron cultivated soils. Activated carbon and Zeolite were used to ameliorate allelopathy activity.

lettuce (Lactuca sativa L.) was used as a test plant and the percentage of germination, hypocotyl length, radicle length and their ratio was evaluated This study was carried out in a completely randomized design with four replications in the Laboratory of Horticultural Sciences, Faculty of Agriculture, the Ferdowsi University of Mashhad in 2018- 2019.

Results and Discussion: The results of this study showed that the allelopathic effect of aqueous and methanol extract of the saffron corm was more effective on germination and seedlings growth of lettuce than 9-year-saffron cultivated soils. The use of activated carbon and zeolite adsorbents was effective in improving and mitigating the allelopathy activity and increased the growth of lettuce seedlings.

Conclusions: the results of this study indicated that it is possible to inhibit allelopathic activity in saffron fields and this study should be repeated in field conditions in order to recommend a practical solution for this purpose.
