Effect of irradiance levels on biomass production, essential oil content and anatomy of Artemisia alba Turra ; Efecto de los niveles de irradiación en la producción de biomasa, contenido de aceite esencial y anatomía de Artemisia alba Turra ; Efeito de níveis de irradiância na produção de biomassa, teor de óleo essencial e anatomia de Artemisia alba Turra

The garden camphor (Artemisia alba Turra, synonimys Artemisia camphorata Vill.-Asteraceae) is an aromatic and medicinal plant that has analgesic, antirheumatic properties to insects bite and injury. Environmental factors such as radiancy interfers in growing condictions of medicinal species making morphological and physiological changing. As purpose the influency of three radiancy levels in the vegetative growth, essential oil level and anatomical characteristics of camphor, were evaluated. At UFLA`s Medicinal Plants Garden, scions developed under three radiancy levels: 100% sunlight, 40% Aluminetâ (60% of sunlight), 80% Aluminetâ (20% of sunlight). Growth evaluations and essential oil level were made at 6 months and 1 year culture. At 6 months there was no significative difference related to accumulation was at sunlight and less at 20% sunlight, total dry biomass was bigger at sunlight at sunlight and at 60%. Essential oil level did not show difference among treatments. With an year culture at sunlight they presented higher total dry biomass accumulation of the leaves and roots. Oil level was higher at 60% and 20% punlight. A higher accumulation in the branches was at 60% and 20% sunlight during the two picking up samples period. In the anatomical characteristics was noticed an increase of the tissues thickness with the increase of sunlight level. Stomato density showed to be higher at sunlight and at 20% sunlight. (Scott-Knott, with 5% ns). ; El alcanfor de jardín (Artemisia alba Turra, sinónimo Artemisia camphorata Vill - Asteraceae) es una planta aromática y medicinal, que tiene propiedades analgésicas, antirreumáticas, para picaduras de insectos y contusiones. Factores ambientales como la irradiancia interfieren en las condiciones de cultivo de las especies medicinales, provocando cambios morfológicos y fisiológicos. El objetivo fue evaluar la influencia de tres niveles de irradiancia sobre el crecimiento vegetativo, el contenido de aceite esencial y las características anatómicas del alcanfor. En el Jardín ...
