Estimating medicinal plants production by using non-destructive parameters in North East Rangelands of Iran

Abstract: Plant biomass is an important factor for determining arid and semi-arid rangelands medicinal plants capacity. The typical methods for measuring biomass are destructive and time-consuming. Thus, they do not allow the development of individual plants to be followed and they require many individuals to be cultivated for repeated measurements. Non-destructive methods do not have these limitations. Green biomass was estimated by using dimensional parameters including Canopy cover, length and wide of diameter and plant height. For each species, 50 flowering stage individual plants of different sizes were randomly selected. The data were analyzed by stepwise regression. The results showed that the dry biomass was significant positive correlations with canopy cover, plant volume, plant height, the length and width of diameters of Ziziphora clinopodioides and Origanum vulgare medicinal plants. The results of stepwise regression showed that just canopy cover and plant volume (canopy cover * height) were remained in the final model, so that 72% of biomass variations were explained by canopy cover and volume in both species.
