Azarnivand et al . (２００５ ) studied the essence of this plant and showed that the essence contains camphor ,camphene , limonene , cineol and careen . In this study we investigated autecological characters of this plant in Kashan .Materials and methods Study area : The study area is in Kashan ( Isfahan province) , located between ３３° ３０′ to ３４° ３０′ N and５１° ４５′ E .Methods of investigation : In this research , the nearest neighborhood method was used for assessment of parameters such asdensity , vegetation cover and plant biomass . Six sites were selected in which ten ５０m transects were done randomly . For each１０m distance , the nearest plant species was determined and the nearest neighbor was chosen .Density : the following formula was used for assessing density :D ＝ １００００ / r ( d２ ) 　 (１ )Where D is Density ( plant per hectares) , d is Average of distance between two plants ( m) , r is Constant number (１ .６７ )Percentage of vegetation cover : We used these formulas :d ＝ d１ ＋ d２ /２ 　 (２ ) ,　 r ＝ d / z 　 (３ ) ,　 s ＝ л r２ ＝ ３ .１４r２ 　 (４ )Where d１ and d２ are Small and large plant diameter , r is Average of crown diameter , s is Area of same circle for vegetation coverS‐ ＝ S１ ＋ S２ ＋爥 Sn / n 　 (５ ) ,　 C ＝ D × S 　 (６ ) ,　 ％ C ＝ C/１００００ × １００ 　 (７ )Where S‐ is Mean of plant cover area , C is Allocated area for each individual plant , D is Density , ％ C is Percentage of plantcover ; percentage of cover was determined using of １０ × １０m plots .Plants biomass : ３０ plants were harvested and plant biomass was calculated using this formula :BW ＝ W × D 　 (８ )Where BW is Plant biomass per hectare , D is Density , W is Mean weight of ３０ plants .Phonological investigation : The observation and recording of plant in dormancy and activity periods was done every ７ and １５days . For soil study ; in each site ５ profiles were sampled at depths of ０‐３０ . Soil texture was assessed by hydrometric method .Results and discussion The results showed that the density was １０４６ plants per hectare , mean vegetation cover was １０ .１３ ％ andmean biomass was ３２７８ kg/ ha . The soils have high levels of lime , and soil depth was shallow to very shallow having stones andmarbles . Precipitation amount is between １４０ to ２５５mm . This plant because of too much essence , similar to Artemisia , can begrazed by livestock after raining . Phenological studies showed that initiation of growth is early April . Vegetative stage is frommid April to last of May . Flowers appear from mid June to September . Seeds form in September .Conclusions P . abrotanoides is a medicinal plant with multipurpose uses . It can be used as valuable forage ; moreover it haspretty flowers that persist for nearly ４ months and the plant can be used for landscaping in arid and semi‐arid regions .ReferenceAzarnivand , H . , Alikhah Asl , M . , Jafari , M . , Dastmalchi , H . , Safari , j . , Joneidi , H . , ２００５ .
