Abstract:

Organic cultivate of medical plants guarantee the quality of them and reduced the probability negative effects on medical quality and yield. In order to evaluate the effects of mycorrhiza inoculation, root juice and citric acid on rooting of the medicinal plant Mentha piperita, this experiment was conducted in 2012 in greenhouse condition at the research field of Islamic Azad University, Karaj branch, Iran. The experiment was conducted in factorial in the form of a completely randomized design with four replications and eight treatments: Mycorrhiza (M0= 0, M1= 100 kg/ha), root juice (R0= 0, R1= 5 cc) and citric acid (C0= 0, C1= 5 mM). Analysis of the variances indicated that application of root juice significantly affected plant fresh weight (P≤0.05) and increased it by 41.3% compared with the control. Applying 5 mM citric acid increased (P≤0.05) root volume by 48.01% and the number of root nodules by 26.1% compared with the control. The interaction of citric acid × root juice had also a significant effect on the number of rooted nodules (P≤0.05); the highest number of root nodules was achieved in C R . The most effective treatments in this study was known citric acid.
