Abstract

The morphological specifications play a substantial role in classification and breeding programs of various plant taxa. In the current study,some macro-and micro-morphological features of Salvia nemorosa, Salvia syriaca, Salvia frigidaand Salvia virgata(three accessions), were investigated using scanning electron microscopy and image analysis program.The completely randomized design (CRD) was used to compare the morphological properties (r=4). Macro-morphological and agronomical measurements showed that Salvia species have great potential for cultivation as medicinal and ornamental plants. The cluster analysis suggested that S. virgata and S. frigida located in the same group; on the other side,S. syriaca and S. nemorosa had more similarity. The micro-morphological results showed that glandular trichomes (GTs) and non-glandular trichomes (NGTs) were widely distributedoverthe leaf and flower surfaces. The peltate GTswithhigh-density coveredsepal and petalandwere observed with low density on the leaves. The comparisonwithdifferent species showedthatthe highest size and density of GTsbelonged to Salvia virgata.The GTsare large and cover a significant portionof the flower surface (3.85-18.45%).The multicellular GTswere observed in S. nemorosaand S. virgataA1and A2. The uniseriate and multicellular NGTscoveredthe adaxial leaf surface in different species.Besides,relative variation inGTswasobserved in the threestudiedS. virgataaccessions (15.33-30.58 trichomes per mm2), whichindicates the roleof environmentalconditionsin trichomes formation. A wide range ofvariation in most of the micro-and macro-morphological traits of Salviagenotypesobserved in cultivated condition.
