- Abstract
A research study was conducted to study floristic of weeds of saffron (Crocus sativus L.) fields located in the Cheshmesaran district in Azadshar to report distribution and species diversity of weeds population. For this purpose, over 3 hectares of saffron fields under cultivation were identified in three regions, including the Narab, Vamenan and Tillabad villages. Identification and sampling of weeds was done in vegetative growth stage of saffron (daughter corms) and 2017. 45 quadrates were used for each farm. Then, the number and type of weed species in each quadrat was counted separately. Weeds species were classified based on their Persian name, scientific name, genus, family, leaf shape, photosynthetic pathway, growth habit and life cycle. The results of species composition of weeds in saffron fields of triple regions showed that the Narab region with 54 species had the largest number of species. Veronica persica Poir weed and Stellaria media in the Narab and Veronica persica Poir in Vamenan were the dominant weeds in these regions which had the highest relative density and frequency. In return, Hordeum murinum has the greatest density and frequency in the Tillabad region. This could be due to the differences in geographical coordinates, climatic conditions of sampling locations, competitive ability of weeds and management methods to control them in saffron fields. The results of species diversity of weeds showed that Narab and Tillabad have the highest and lowest dominance index, which are about 0.13 and 0.08, respectively. In return, the highest Menhinick richness, Margalev and uniformiy of weeds were recorded in the Narab region which were about 0.67, 2.55 and 0.97, respectively. Narab and Vamenan regions also had maximum numerical value of Simpson (0.92) and Shannon-Wiener indices (2.64). Overall, the results show that saffron fields of both Narab and Vamenan regions were most similar in term of weed species, number and population indices
