Allelopathic Effects of Root Exudate and Leaching of Rice Seedlings on Hedgemustard (Sisybrium officinale)
Homa Mahmoodzadeh, Forugh Abbasi and Yalda Ghotbzadeh

Abstract:
To determine the allelopathic potential of root exudate from early developmental stage of rice (Oryza sativa L.), 6-days-old seedlings of two cultivars were grown with 3-days-old Hedgemustard seedlings in petri dishes under controlled condition. There were 4 treatments (2, 4, 8 and 10 days). Also rice leachate was used for germination test of the weed. Rice lichate caused pronounced inhibitory effect on seed germination and germination rate of receptor plants. Root exudates of rice cultivars also inhibited root and shoot growth and fresh weights of seedlings of receiver plants. Effectiveness of cv. kalat was more than cv. shomal. Hence, it could be concluded that the rice root exudates and rice leachate contain water-soluble allelochemicals which could inhibit the seed germination and reduce seedling growth of Hedgemustard.
