بررسی اثرات دگرآسیبی عصاره آبی بنه زعفران بر رشد گیاهچه‌ای منداب در شرایط آزمایشگاهی

Saffron (Crocus sativus L.) intercropping with other plants needs to preliminary investigations on the possible allelopathic effects between saffron and selected crop. In current study the effect of corm extract of saffron on germination and seedling growth of arugula (Eruca sativa Mill.) was investigated based on a Completely Randomized Design with three replications at crop physiology laboratory of Agriculture Faculty of Sarayan, Birjand University in 2013. Experimental treatments were consisted of different levels of saffron corm extracts including 0, 0.75, 1.5, 3 and 6%. Results showed that the effect of experimental treatments was significant on all germination and early seedling growth indices of arugula. The highest amount of germination percentage was obtained at control treatment (92%), but with increasing in extract concentration, this index decreased, so that the lowest value of germination percentage was gained in highest concentration of corm extract (72%). Relatively similar results were observed about the germination rate and root and plumule length and dry weights.
