All is one of important medicinal plant belong to Compositae family and it grows as wild species in Zagros and Alborz Mountains, Iran. The aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. Seeds of seven accessions were sown in jiffy pots and transferred to field using randomize block design with three replications in Alborz research station, Karaj, Iran during 2011-12. Data were collected and analyzed for canopy diameter, plant height, flower number, flowering date, maturity date, shoot fresh and dry weight, Essential oil percentage and GDD to flowering and maturity dates. Results showed significance differences for all traits (P<%1) except of essential oil percent. Populations of Gorgan1 and Gorgan2 had higher values for essential oil yield and shoot yield than other populations. Population of Loshan flowered earlier than other population due to low values of its growth degree days (GDD). Simple correlation analysis showed that shoot dry weight was positively correlated with shoot fresh weight, canopy diameter, flower number, and negatively correlated with flowering and maturity date. Essential oil content was positively correlated with flower number and negatively correlated with flowering and maturity date. Results of stepwise regression analysis for essential oil% as dependant variables and other traits as independent variables showed negative effects of flowering and maturity date and positive effect of canopy diameter on essential oil content. Similarly, for essential oil yield as dependent variables, the shoot dry weight, essential oil%, flowering date and GDD were entered in final regression equation. The results of path analysis showed that maturity date had negative direct effect on oil%. In contrast, both Shoot dry weight and essential oil% had positive and direct effect on oil yield.

In order to study of seed priming effects on seedling growth of chamomile, an experimental design, based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests and Rangelands in 2014-2015. Experimental factors were A) three chamomile accessions as code of gene bank 8959 (Brojen), 15123 (Arak) and 23879 (Isfahan), B) five conservation methods including: medium-term storage (active cold room 4 C for 15 years), long-term storage (basic cold room-18 C for 15 years), regenerated seeds in open storage 22 C for 2 years (Control) and aged seed under accelerated ageing (40 C,98% of relative humidity for 48 and 72h) and C) priming treatments including: without priming /(control), osmopriming (PEG-0.3Mpa), hormonal priming (Gibberllic acid 250 and 500ppm), hydropriming (imbibition with distilled water). Data collected for seed emergence percent, root and shoot length, seedling length, vigor index, seedling weight and three Proxidase, Catalase and Super Oxid Desmotaz (SOD) enzymatic activities. Variance analysis showed significant effects of all factors and their interactions except accession by conservation interaction effects for seedling length (P<0.01). Result showed that that accession two accessions 23789 (Esfahan) and15123 (Arak had higher mean values than one other accessions for most of the traits in both medium-term and long-term storage. For aged seeds, the higher root length, seedling length mean values were obtained in 48h accelerate aging test. In comparisons between priming treatments, the higher means of traits were obtained in osmopriming except germination percent. For enzymes activity the trends of accession were not similar but the effect of osmopriming on catalase activity were high and stable in three accessions. The result of priming by conservation interaction showed that the higher seed emergence was obtained in regenerated seeds (control). The higher root length was obtained in accelerated aging test by application of all of priming treatments except hydropriming. For vigor index, hormonal priming (GA250) had higher effect followed by osmopriming. Similarly, for enzymatic activities GA500 had significant impact on proxidas and catalase. It was proved that two priming technique Osmo-priming using (PEG) and hormonal priming (Gibberllic acid) were effective method for recovery of aged seed.

The base temperature (4°C) were applied on 15th days seedling age for 30 days for vernalization compare with control. The pots were return in normal conditions besides control pots in greenhouse and then outdoor. The pots were arranged using factorial experiments based on completely randomized design with three replications. The plants had grown up to their flowering and maturity stage. In flowering stage, morphological traits including: plant height, peduncle length, panicle length, flag leaf area and flag leaf length, fresh and dry weight and seed yield and quality traits as dry mater digestibility (DMD), crude protein (CP), water soluble carbohydrates (WSC), acid detergent fiber (ADF) and total ash (ASH) were recorded. Results showed that populations of Mashhad, and Brojen had higher values for fresh and dry weight than those of other populations. For plant height, peduncle length, flag leaf area the Brojen, Bojnord and Kamyaran had higher values, respectively. For quality traits, the higher values of both DMD (56.5%) and WSC (14.09%) were obtained for Esfahan and higher value of CP (18.1%) for Bojnord. Results also showed that the growth degree days (GDD) of those populations which were subjected to cold treatment was lower flowering stage than those for control. It was concluded that cold treatment had no effect on vegetative developments particularly in seedling stage, but it reduced flowering dates in generative stage and increased plant dry matter yield. It was proved that the Tall fescue is cool season grass and it needs a period of vernalization for promotion of flowering.
