Abstract
Legumes are common crops in arid and semi-arid regions. This study was conducted to investigate three levels of salinity stress on 18 lentil cultivars in the greenhouse and laboratories of Mohaghegh Ardabili University in 2016-2016 in a factorial manner in the form of a randomized complete block design with three replications. The results of comparing average lentil genotypes were done with Duncan's method at the five percent probability level. Correlation was done in separate stress levels. The dendrogram of cluster analysis divided the genotypes into three groups in control and 60 mM conditions and two in 120 mM conditions. Genotypes 7 and 5 were in the top group in all groupings. The relationship between ISSR molecular markers and physiological traits was calculated among genotypes. All traits in three levels of salinity stress had a significant correlation with some ISSR markers. A total of 22 positive markers for physiological traits were identified at the control level, 9 positive markers at the moderate stress level, and 23 positive markers at the severe stress level. Among the 21 studied ISSR primers, the P8A11 marker had the largest number of gene loci related to the studied physiological traits.

Abstract
: Alcea species are valuable medicinal plants used in traditional medicine for a long time. The similarity between species and the diversity of traits have led scientists to use various biosystematics methods to identify species. In this study, the anatomical characteristics of the stem in 18 species of Alcea from Iran were examined. Hand sections in similar positions of the stem were studied and double staining with methyl green and carmine stain, and microscopic images were obtained. The most important traits analyzed in this study were the number of layers of collenchyma cells in the cortex, the thickness and number of layers of sclerenchyma fibers of the phloem, the number of vascular bundles, the ray parenchyma, the thickness of phloem and xylem vessels, and the structure of the pith. Then, cluster analysis using the Ward method was performed with SPSS software based on eight quantitative traits. The results showed that some of the stem's anatomical features, which are observed in closely related species, can only be useful for species identification but are not particularly helpful in grouping the species
