Karyology of Iranian Endemic <i>Satureja</i> (Lamiaceae) Species

karyological and nuclear dna content variation in some iranian endemic thymus species (lamiaceae)

thymus is a medicinal plant which contains one of the world's top ten essential oils, exhibiting antibacterial, antioxidative, food preservative and mammalian age-delaying properties. this work was aimed at identifying between-species variations requiring for selecting appropriate parents for hybridization. six iranian endemic thymus accessions belonging to thymus daënensis, t. eriocalyx and t....

Karyology Study of Ten Trifolium Species in Fars Province

Chromosome information is an important key for taxonomy, phylogeny and genetic in Trifolium plants. Thus, ten Trifolium species namely T. grandiflorum, T. resupinatum, T. dasyurum, T. campestre, T. tomentosum, T. hirtum, T. scabrum, T. lappaceum, T. stellatum, and T. repens were collected from their habitats in Fars province based on their morphologi...

Xeromorphism of trichomes in Lamiaceae species

The xeromorphic adaptation of epidermal cells of Lamiaceae plant leaves, the conse­ quence of their adaptation to an arid habitat, was investigated. These xerophytic species inhibit transpiration in different ways, depending on the number, the form and the position of trichomes, whether they are dead hairs or live glandular structures. The Salvia genus is characterized on one hand by multicellu...
