Stem Segments

Callus of Rosmarinus officinalis L. 'Lockwood de forest' was induced from stem segments (3 mm long) using different concentrations of thidiazuron (TDZ). The original stem segments used as explants were found to have a higher level of linalool than was found for leaf segments. Linalool is one of the monoterpenes identified in rosemary plants and it has a pleasant aroma. TDZ has a significant effect on callus formation and callus texture. The callus formed was light green to yellow and/or had some meristimatic dark green cells. TDZ had a significant linear effect on the callus fresh weight. The meristimatic green cells formed on all calli except those proliferated on the lowest concentration of TDZ (0.5 mg/l). No callus was induced from stem segments cultured on TDZ-free medium. The fresh calli from other treatments were soaked in hexane as a solvent for monoterpene analysis using GC/MS. No monoterpenes could be detected in the callus induced on the medium containing the lowest concentration of TDZ. Comparing to the stem segments taken from the parent plants only 4 of 10 monoterpenes identified were found in the callus: α-pinene, β-pinene, 1,8-cineole, and camphor.

Dark Green

Rosmarinus officinalis L. commonly known as Rosemary belong to the family Lamiaceae. It is an aromatic herb which is hardy, dense and evergreen in natural habitat. It is one of the medicinal plants which is cultivated around the world for its medicinal, therapeutic purpose and is used as condiment and food preservative. It is one of the oldest Mediterranean shrub having strong, pungent aroma having dark green and elongated leaves with white or purple flowers. It is a perennial herb reaching 100 to 210 cm in height having pointed and hairy, resinous dark green leaves with lower white surface. The present study review about macroscopical/botanical description of Rosmarinus officinalis L. and its methanolic extraction analysis for preliminary quantification of chemical constituents by visualizing TLC plate under different wavelength of UV light i.e., 255nm, 366nm and 566nm to get chromatograph by HPTLC.

Colletotrichum Musae

A banana apresenta elevada suscetibilidade a doenças como as podridões que diminuem o tempo de prateleira do fruto. Uma das formas de controlar as doenças seria a utilização de métodos alternativos como os extratos de plantas medicinais. Assim, o objetivo deste estudo foi verificar a ação de formulados de alecrim (Rosmarinus officinalis L.) pó e líquido no controle de antracnose causada pelo fungo Colletotrichum musae (Berk & Curt.) Von Arx. e na maturação de banana ‘Nanicão’ em pós-colheita. Foram utilizadas as concentrações 0%; 0,25%; 0,5%; 1%; 1,5% e 2% do pó solúvel de extrato de alecrim diluído em água destilada, e as concentrações 0%; 0,5%; 1%; 2%; 4% e 6% do formulado aquoso contendo 21% de resíduo seco de alecrim diluído em água destilada. Foi realizada a mensuração da área de cada fruto e avaliada a severidade e a maturação a partir de porcentagem de área dos frutos, sendo os resultados utilizados para calcular a área abaixo da curva de progresso da doença (AACPD) e a porcentagem de maturação dos frutos. Realizou-se analise de regressão a partir dos dados obtidos e pode-se verificar que para o formulado de alecrim em pó a AACPD reduziu mais de 29% e para a maturação a redução foi de 21,72%. Para o formulado líquido a redução foi de 14,31% para AACPD e cerca de 10% para maturação. Assim, concluiu-se que houve eficiência por parte dos formulados de alecrim no controle da antracnose e no aumento da vida de prateleira da banana ‘Nanicão’.
