G1K 7P4, Canadc1998///  a1515 - 15200 v473 aThe essential oils from two clonal types of Thymus vulgaris (Laval-1 and Laval-2) were characterized and tested for antifungal activity. Contents were high in p-cymene, linalool, terpinen-4-ol and thymol which constituted 53.5% and 66.2% of Laval-1 and Laval-2 essential oils respectively. The essential oil volatiles from two clonal types exhibited antifungal activity against Botrytis cinerea and Rhizopus stolonifer, two common storage pathogens of strawberries (Fragaria ananassa). The inhibition of B. cinerea and R. stolonifer ranged from 26.5 to 63.5% and 5.5 to 50.5% respectively by oil from Laval-1, when exposed to concentrations of 50 to 200 ppm, while values of 36.9 to 90.5% and 11.5 to 65.8% were observed from oil from Laval-2. The decay of strawberry fruits caused by B. cinerea and R. stolonifer was controlled up to 73.6 and 73.0% respectively by volatiles from maximin concentration of Laval-l, and up to 75.8 and 74.8% from Laval-2. No visual phytotoxic symptoms were noticed for the observed period. Essential oil from Laval-2 exhibited higher antifungal activity which was related to its relatively higher content of antimicrobial compounds.10aAntifungal10aBotrytis cinerea10aFragaria ananassa10aLabiatae10aRhizopus stolonifer10aRosaceae10aStrawberries10aThyme10aThymus vulgaris10aVolatile components1 aReddy, M, V B1 aAngers, P1 aGosselin, A1 aArul, J  uhttp://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-0032051755&partnerID=40&rel=R6.5.002039nas a2200145   4500008004100000245016100041210006900202260001400271300001400285490000700299520142800306100001601734700001601750856012701766       1995                        eng d00aEffects of Hps Supplemental Lighting and Soil-Water Levels on Growth, Essential Oil Content and Composition of 2 Thyme (Thymus-Vulgaris L) Clonal Selections0 aEffects of Hps Supplemental Lighting and SoilWater Levels on Gro  c1995/01//  a231 - 2380 v753 aThe growth, essential oil content and composition of two clonally selected Thymus vulgaris plants were each significantly affected by two light regimes (LR) and three different soil water levels (SWL). The highest dry matter accumulation was achieved from plants grown under supplemental light (SL) at 90% SWL. The leaf area increased linearly from 959 cm(2) to 1635 cm(2) for Selection 1 and from 543 cm(2) to 1322 cm(2) for Selection 2 under natural light and from 1180 cm(2) to 3512 cm(2) for Selection 1 and from 958 to 2821 cm(2) for Selection 2 under supplemental light, respectively, for plants grown under 50 to 90% SWL. The coefficient of correlation between shoot yield and leaf area was highly significant (r(2) = 0.96). However, maximum essential oil content and yield per plant were recorded at 70% SWL for Selection 1 grown under SL. There were significant shifts in the content of phenols, particularly in monoterpene hydrocarbons in the essential oil, due to the differences in LR and SWL. The major constituent of the essential oil, thymol, accounted for the shift from about 48.6% to 85.5% for Selection 1 and the shift from 47.2% to 68.9% for Selection 2, depending on the treatment levels. Our data showed a maximum level of 85.5% thymol accumulation in the essential oil of Selection 1 grown at 70% SWL under SL. We established that both selections under investigation belonged to the thymol chemotype.1 aLetchamo, W1 aGosselin, A  uhttps://thymus.myspecies.info/ref/effects-hps-supplemental-lighting-and-soil-water-levels-growth-essential-oil-content-and02260nas a2200277   4500008004100000245006500041210006100106260026900167300001400436490000700450520121500457653001401672653001501686653003001701653001401731653002401745653001301769653001001782653001101792653002001803100001601823700001601839700001401855700001601869856009701885       1999                        eng d00aThe selection of Thymus vulgaris cultivars to grow in Canada0 aselection of Thymus vulgaris cultivars to grow in Canada  aAffiliation: Horticultural Research Centre, Department of Plant Science, Fac. of Agric. and Food Laval Univ., Qué., G1K 7P4, Canada; Affiliation: Institute of Pharmaceutical Biology, Philipps University of Marburg, Deutschhauserstr. 17A, Germany; Affilic1999///  a337 - 3420 v113 aFive different cultivars of Thymus vulgaris originating from various geographical sources (Canada, Germany, former GDR and Spain) were organically cultivated in the fields in Quebec, Canada. The oils obtained through steam distillation of the dried leaves from each cultivar varied from 1.38% to 2.04%, depending on the cultivar used. The highest oil content was obtained from cv "Madrid" followed by "RH-1" and "Laval-1." More than 95% of the oil, with a total of approximately 22 components were identified in the samples. Oxygenated monoterpenes were the main group of constituents in all cultivars. Cultivar "Laval-1," recently developed in Quebec, "Madrid" from Spain and "RH-1 " from Germany were established to belong to thymol-chemotypes. Cultivar "QDLB" characterized by its content of thymol (approximately 39%), carvacrol (17%) and linalool (3.5%), in the oil, was also found to belong to "thymor-chemotypes, while "RH-2" with carvacrol (40%) was found to be a carvacrol-chemotype. Though none of the cultivars had the desired levels of linalool content, "Laval-1" and "RH-1" were found to be prospective cultivars for field commercial organic cultivation in Canada. © 1999 Allured Publishing Corp.10aCarvacrol10aChemotypes10aEssential oil composition10aLamiaceae10aOrganic cultivation10aP-cymene10aThyme10aThymol10aThymus vulgaris1 aLetchamo, W1 aGosselin, A1 aHoelzl, J1 aMarquard, R  uhttp://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-0347421484&partnerID=40&rel=R6.5.0
