Sexual and asexual propagation of Baccharis dracunculifolia DC., a dioecious me...
Tomazzoli, Maira Maciel; Amaral, Wanderlei do; Tomasi, Jéssica de Cássia; Belniaki, Andreza Cerioni; Panobianco, Maristela; Zeviani, Walmes MarquesBaccharis dracunculifolia DC. is a pioneer plant native from Brazil that has great importance due to its secondary metabolites (essential oil and Brazilian green propolis) and its potential in the recovery of degraded areas. The main goal of this study was to evaluate the propagation techniques of B. dracunculifolia by sexual reproduction and asexual propagation of male and female stem cuttings. For reproductio...

Spader, Vitor; Deschamps, CíceroO trabalho objetivou avaliar o comportamento de cultivares de soja, em diferentes épocas de semeadura e densidades de plantas. Dois experimentos foram conduzidos na FAPA Fundação Agrária de Pesquisa Agropecuária), localizada na latitude 25?33’ S, longitude 51?29’ W e com 1.00 metros de altitude, em Guarapuava, PR, Brasil, em dois anos agrícolas(). O delineamento experimental foi o de blocos ao acaso, com arranj...
Development, essential oil yield and composition of mint species and chemotypes...
Deschamps, Cícero; de Castro, Luciana Witoslawski Piratello; Machado, Marília Pereira; Scheer, Agnes de Paula; Côcco, Lilian CristinaRadiation and soil nutrient levels affect essential oil production in aromatic plants. The objective of this work was to evaluate the vegetative development, essential oil yield and composition of Mentha aquatica L. (linalool chemotype) and Mentha x piperita L. (linalool and menthol chemotypes) cultivated under different radiation levels (100%, 46% and 23%), and with or without nitrogen fertilization. The essen...
Vegetative development and production of essential oil of Patchouli under radia...
Storck, Rafaellen Caroline; Deschamps, Cícero; Côcco, Lílian Cristina; Mógor, Átila Francisco; Scheer, Agnes de Paula; Yamamoto, Carlos ItsuoPogostemon cablin Benth. has economical importance due to the essential oil which is used in the pharmaceutical and perfume industries. Among the environment factors, the radiation is extremely important for plant development and its limitation can result on decrease of yield. The application of gibberellins promotes the cellular elongation resulting on increase of plant height. Therefore, the radiation level a...
Seasonal variation of vegetative growth, essential oil yield and composition of...
Santos, Vera Maria Carvalho Silva; Pinto, Marco Antônio Silva; Bizzo, Humberto Ribeiro; Deschamps, CíceroMenthol has economic importance to the flavor, food and pharmaceutical industries. Ten menthol mint (Mentha spp) genotypes were assessed for essential oil content and composition at Southern Brazil environmental conditions at two harvest times (February and May). The experimental design was in completely randomized blocks with a 10 x 2 factorial for genotypes and harvest time. The essential oil was obtained by ...
Bipolaris sorokiniana control and grain yield in barley after application of el...
Antoniazzi, Noemir; Deschamps, CíceroThe disease spot blotch, caused by the fungi Bipolaris sorokiniana, is considered one of the most important phytosanitary problems of barley crop resulting on low productivity and damage on beer quality. The objective of this work was to evaluate the effect of the elicitors xanthan gum and alicin and fungicide epoxiconazole + pyraclostrobin on spot blotch control of barley cultivar BRS 195 during two cultivatio...
