“…The yield obtained for Brassica accessions in the present study is interesting, since the medium-low yield of B. napus species in Brazil is 1500 kg•ha -1 (Silva et al 2017). Improved efforts are needed to increase the yield of Brassica species that have high erucic acid content.…”

Brassica oilseed species are becoming increasingly popular for industrial uses, with emphasis on biodiesel. It is of importance to evaluate the yield and oil production potential of nontraditional oilseeds for use as feedstock in Brazil. In this study, growth, yield, and oil content and their correlations were determined for eight accessions of B. juncea and B. rapa in two years under tropical conditions of southeastern Brazil. Significant variation was observed between B. juncea and B. rapa accessions for yield components and oil content. B. rapa was the earliest maturing and had the highest oil content, whereas B. juncea had the highest number of pods and the highest yield and oil yield. Brassica rapa accessions flowered early, with an average cycle of 97 days, whereas B. juncea reached maturation after 110 days on average. Accessions were grouped according to the oil content of each species, with the most promising accessions having an oil content of 45-47%. Accessions of Brassica species had high oil yields, reaching 910 kg ha-1 of oil yield for B. juncea PI 180266. There was a linear correlation between oil content and thousand seed weight, pod length, and seeds per pod of the Brassica species accessions. Considering oil content and oil yield across years, Brassica species show promise as alternative oilseed crops for biodiesel production in tropical conditions.

“…It contains around 40% of oil and about 38-43% protein (Shahidi 1990). For this reason, canola is an important feedstock for biodiesel production (Gonçalves et al 2017) and, at the same time, a potential ingredient for use in the food industry (Aider & Barbana 2011). The commercial production is broadly supplied by two species: Brassica napus L. and Brassica rapa L. (Raymer 2002).…”

Diversity of Stink Bugs (Pentatomidae) Associated with Canola: Looking for Potential Pests

et al. 2018

Canola (Brassicaceae: Brassica spp.) is an important feedstock for biodiesel production and a potential ingredient for use in the food industry. In different continents, various arthropod pests damage canola plants. Stink bugs (Heteroptera: Pentatomidae) are present in all zoogeographical regions, and many species are recognized by their economic importance as crop pests. Our aim was to describe the composition, structure, and diversity of the assemblage of stink bugs sampled on canola in southern Brazil. A total of 878 pentatomids were captured, belonging to 27 species. The dominant species were Euschistus heros (F.) (n = 439), Dichelops furcatus (F.) (n = 160), and Nezara viridula L. (n = 79). The species richness estimators indicated the samples correspond from 79.7 to 93.1% of the richness estimated. Comparing canola to other monocultures, the richness of Pentatomidae was much superior. Otherwise, when compared to studies conducted in native vegetation and urban fragments, the richness is similar, and sometimes higher. This relatively high number of associations brings out the vulnerability of the canola fields according to the expansion of its cultivated area. Nine species of Pentatomidae are recorded on canola for the first time in Brazil. The most abundant species reported here are often stressed as stink bugs of economic importance in agro-ecosystems. The economic importance of each species varies greatly depending on the plant attacked. Detailed studies are needed to evaluate the damage caused to canola by stink bugs.

“…No Brasil, na safra 2019, a área plantada foi de 34 mil hectares, produzindo 46 mil toneladas de grãos, com produtividade média de 1.353 kg ha -1 [3]. Entre os principais usos do grão, tem-se a extração de óleo para consumo humano, fabricação de sabão e, produção de biocombustível, gerando assim um sub-produto, o farelo, que pode ser utilizado na formulação de rações para animais [4,5,6].…”

A canola é uma cultura que tem crescido no Brasil, e trata-se de uma fonte produtora de óleo. É uma cultura adaptada a climas frios e o conhecimento sobre o desenvolvimento inicial da canola pode contribuir para um melhor entendimento e estabelecimento destes híbridos em outras regiões. Objetivou-se avaliar o desempenho de plântulas de canola sob variação da profundidade de semeadura e diferentes substratos. Desta forma, foi conduzido um experimento em campo, em ambiente protegido, usando um esquema de parcelas subdivididas 2x2x3, dois substratos (areia e solo), com dois híbridos de canola (Hyola 61 e Hyola 433), em três profundidades de semeadura (1, 2 e 3 cm), com oito repetições, resultando em 96 unidades experimentais. Em cada unidade experimental semearam-se 25 sementes que foram avaliadas por meio da contagem diária da emergência, até o ponto de sua estabilização, que ocorreu no décimo dia. Assim, se iniciaram as avaliações definidas de Comprimento de raiz (CR), Comprimento de plântula inteira (CPI), Altura de plântula (ALT), Plântulas normais (PN), Plântulas anormais (PA), Emergência de plântulas (E), Índice de velocidade de emergência (IVE), Massa fresca de plântulas (MFP) e Massa seca de plântulas (MSP). Observou-se que os híbridos tiveram melhor desempenho em substrato solo, com superioridade do hibrido Hyola 433 na semeadura a 1 cm de profundidade.
