The Study Of Dispersion And Ecology Of 36 Species Aromatic Plants In Mazandaran

In this consideration 36 aromatic plant species depending to labiateil.abiatae) family studied in Mazandaran province. The factors ecological studied in habitats aromatic plants were involved slope percentage.aspect.height.soil of texture, climate, yearly precpitation and temperature mean.cover percentage.the best habitat with respect to abundance and density, vegetation types.dispersion, companion plants and phenology. The results show that some of plants species are indicator plants of environmental conditions. Indicator plants of very cold mediterranean climate and over 3000 meter height are betony(Betonica nivea subsp mazandarana), motherwort (Leonurus cardiaca). Indicator plants of sub-dry cold climate (250-300mm precipitation) are hymenocratertliymenocrater calycinus),hedge nettle (Stahys turcoma nica) , desert rod (Eremostachysmacrophylla), (E.lahiosiformis) field-basiltZiziphora tenuior),cat thymet'Ieucrium chamaedryst.Indicator plants of humid climate are hedge nettle (Stachys persica), calaminthttlalamintha grandiflora). The greatest abundance of plants occured in cold mediteranean climate .Indicator plant olluvial and slopy foothill is catmint(Nepeta saccharrataj.Indicator plants of dislocated and bare foothill in forests and woodlands are wild marjoram(Origanum vulgare), hedge nettle (Stachys setifera) .horehound (Marrubium vulgare). Indicator plants of edge small rivers are calaminth(Calamintha grandijlora),catmint(Nepeta cataria) .Indicator plants of unutilized drylands between forest and rangelands are hedge nettlet Stachys byzanthinaj.Indicator plants of little saline soils are hedge netlle(Stachys inflata) and afghan silver sagetl'ervoskia abrotanoides). The plant species such as hedge netlle (S.hyzanthina ,S.lavandulifolia), Tltymet'Thymus pp), cat thyme (Teucrium poliumtare very abundant and betonytli.nivea ubsp mazandarana), hymenocrater (Hicalycinus .R .elegans) , desert rod (E.macrophylla Elabiosiformis), calaminth (Calamintha officinalis),hedge nettle (Sisetifera) .catmintt Nepeta cataria), field-basil (Ziziphora ten u ior) , catmint(Nepeta pungens) are rare plants species in Mazandaran.
