Abstract: The main limitation of the micropropagation of camu-camu (Myrciaria dubia) is related to in vitro contamination. In order to overcome contamination, the effect of essential oils was studied as an alternative to conventional chemical treatments. This study aimed to analyze the action of essential oils from four condiment and medicinal plants (Oregano, Origanum vulgare L.; Garlic, Allium sativum L.; Citronella, Cymbopogon nardus L.; and Ginger, Zingiber officinale Rosc.) in reducing microbial contamination growth and on the survival rate of explants in the micropropagation of camu-camu. Resumo: A micropropagação de camu-camu (Myrciaria dúbia) tem como principal limitação a contaminação in vitro. A fim de superar a contaminação, o efeito dos óleos essenciais foi estudado como alternativa aos tratamentos químicos convencionais. Este estudo teve como objetivo determinar a ação dos óleos essenciais de quatro plantas condimentares e medicinais (Orégano, Origanum vulgare L.; Alho, Allium sativum L.; Citronela, Cymbopogon nardus L.; Gengibre, Zingiber officinale Rosc.) na redução de contaminação microbiana e sobre a taxa de sobrevivência dos explantes na micropropagação de camu-camu. |

The aim of this study was to evaluate the potential of luteal echotexture (mean pixel value and heterogeneity), as a tool for assessing luteal function during different phases of the estrous cycle in Toggenburg goats. Sonographic evaluations of the ovaries were performed daily in nulliparous goats (n = 21), using a 5MHz linear rectal probe, commencing at estrus (day 0). Blood samples were collected daily for plasma progesterone RIA and images recorded on VHS tape and then digitized in TIFF format at a resolution of 1500×1125 pixels. A representative elementary area (REA) of 5625 pixels (0.31cm2) of these images was analyzed using custom-developed software, for mean pixel value and heterogeneity. Mean plasma progesterone, luteal area and pixels all reached maximum values at approximately days 13 and 14, during luteogenesis. Luteolysis was characterized by an abrupt decrease in blood progesterone concentration following ovulation, and a gradual decline in luteal area and pixel values. The luteal tissue area was positively correlated with plasma progesterone concentration during both luteogenesis (r = 0.63; P < 0.05) and luteolysis (r = 0.50; P < 0.05). Weak correlations were recorded between the mean pixel value and luteal tissue area during luteogenesis (r = 0.34; P < 0.05) and luteolysis (r = 0.26; P < 0.05). Similarly, weak correlations between the mean pixel value and plasma progesterone concentration were recorded during luteogenesis (r = 0.24; P < 0.05) and luteolysis (r = 0.37; P < 0.05). The pixel heterogeneity was not correlated with luteal tissue area or the plasma progesterone concentration at any stage of the estrous cycle. The results show the association between the corpus luteum echotexture and steriodogenic function to be weak and the present ultrasound technology, to have limited potential in evaluating luteal function in goats.
