The morphological, yield, and phytochemical characteristics of Solidago virgaurea L. were studied at the full flowering stage in two habitats of Pol Sefid and Sang Deh in Mazandaran province in 2019. The traits including plant height, plant diameter, inflorescence length, number of stems, length and leaf width, length and ray floret width, tubular floret length, flower diameter, receptacle diameter, stem diameter, fresh and plant dry weight, fresh and leaf dry weight, fresh and stem dry weight, fresh and leaf+flower dry weight, and total phenols (by Folin-Ciocalteu method), flavonoids (by aluminum chloride method), and leiocarposide (by HPLC) contents were measured. The results showed that the highest amounts of inflorescence length (40 cm), flower diameter (21.1 mm), plant dry weight (9.44 g plant-1), flower dry weight (6.06 g plant-1), flower+leaf dry weight (7.22 g plant-1), and stem dry weight (2.22 g plant-1) were obtained in the population "Pol Sefid". A positive and significant correlation was observed between the plant dry weight and traits including the plant height, number of stems, stem diameter, flower diameter, plant fresh weight, fresh and leaf dry weight, fresh and stem dry weight, fresh and leaf+flower dry weight, and total flavonoids. The content of total phenols (26.95 mg Gallic acid/g DW), total flavonoids (8.82 mg Rutin/g DW), and leiocarposide (2.08 mg/g DW) was higher in the population "Sang Deh" than "Pol Sefid".

Licorice (Glycyrrhiza glabra L.) is one of the oldest and most important medicinal plants in Fabaceae, used for curing many diseases since 4000 years ago. This study was conducted to evaluate the genetic diversity of 22 different licorice populations based on morphological and yield traits at the research field of the Faculty of Agriculture, Zanjan University, during 2016 to 2018. Morphological and yield traits including plant height and width, leaf length and width, number, length and width of leaflets, number of lateral branches, main stem diameter, aerial parts fresh and dry weight, root fresh and dry weight, root to aerial parts ratio and aerial parts and root yields (per m2) were measured. Canonical discriminant (CDA) and cluster (CA) analyses were used to group the populations. In CDA, the first two canonical variables were significant. The first canonical variable included plant height and width, main stem diameter, leaf length and the number of leaflets, and the second one included aerial parts fresh and dry weight, root fresh and dry weight, root and aerial parts yields. The second canonical variable had the greatest role in population separation and grouping. Canonical variables divided populations into four main groups and confirmed CA clustering results. In general, the results indicated the good potential of canonical discriminant analysis in evaluating the genetic diversity and identifying the index traits in licorice.
