| 2 | Effect of Organic Fertilizer Doses on the Plant Growth,Essential Oil Production and Chemical Substances of "Carqueja" over Two Harvest Moments显示文摘This study aimed to investigate, for the first time, the plant growth, essential oil content and their chemical substances ofBaccharis trimera (Less.) DC., the first Brazilian variety of medicinal plant, in response to five doses of organic fertilizer (0, 10, 20,30, 40 and 50 ton/ha) over two harvest moments-120 d and 242 d after transplanting (DAT). The work was carried out fromFebruary to October 2011 at the experimental farm of the Sao Paulo State University "Julio de Mesquita Filho" (UNESP), Brazil.The seedlings of B. trimera var. CPQBA-1 were respectively transplanted into experiment plots under six treatments: 0, 10, 20, 30,40 and 50 ton/ha of organic fertilizer. Each treatment had four replications and each plot consisted of 12 plants. Then they wereharvested at 120 DAT and 242 DAT, and the essential oil were extracted by hydrodistillation and analyzed by gas chromatograph.The results were subjected to analysis of variance and the means were analysed using Tukey's test (5%) followed by a regressionanalysis. The fertilizer dose significantly influenced the height of the plants in the second harvest, while the higher dose of organicfertilizer positively impacted the essential oil content in the first harvest. Also, the level of organic fertilizer was directly correlatedwith the production of dry matter during the regrowth. Twenty-seven substances were identified in the essential oil samples, and themajor components were: bicyclogermacrene, trans-caryophyllene, germacrene-D, spathulenol and caryophyllene oxide. Thesefindings suggest that to obtain higher yields of dry matter ofB. trimera, it should be harvested around 242 DAT and organic fertilizershould be applied approximately to 50 ton/ha. Furthermore, higher doses of organic fertilizer and harvest at 120 DAT is able toincrease the essential oil content. | Daniel Garcia Paulo Sérgio Siberti da Silva Marcos Roberto Furlan Monica Tiho Chisaki Isobe Marcia Ortiz May Marques Lin Chau Ming | 2017 | Journal of Agricultural Science and Technology(B)2017，7，2： | 0 |
