This study aimed to determine flavonoids levels contained in each of jatropha plant samples to be used as an alternative affordable free radicals deterrent. The flavonoid content was analyzed using UV-Vis spectrophotometry. Stem of the three samples was extracted using HCl. The results showed that total flavonoids levels contained in each stem of Jatropha curcas L., Jatropha gossypifolia L., and Ricinus communis L. were 3.959 mg/L, 1.309 mg/L, and 0.083 mg/L, respectively.

Extraction of oils from castor bean (Ricinus communis L.) and Jatropha curcas L. to produce biofuel is set to increase. The produced seed cake could be applied to soil as it is nutrient rich, but might affect soil functioning. Seven soils from Chiapas, M&eacute;xico, were amended with seed cake of both plants while CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O emissions and mineral N concentrations were monitored in an aerobic incubation. The concentration of phorbol esters in the J. curcas seed cake (JSC) was 0.993 mg/g while no ricin was detected in the R. communis seed cake (RSC). Application of JSC increased CO<sub>2</sub> emission 2.5-times, N<sub>2</sub>O 12.6-times and CH<sub>4</sub> 18.4-times compared to the unamended soil, while RSC CO<sub>2</sub> emission 2.1-times, N<sub>2</sub>O 21.3-times and CH<sub>4</sub> 2.3-times. On average, 66% of the 88 mg organic N added with JSC was mineralized and 83% of the 101 mg organic N of the RSC within 56 days. It was found that J. curcas and castor bean seed cake increased CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O emission and mineral N in soil, without inhibiting soil microbial activity.

Jatropha curcas L. (2n = 2× = 22) is increasingly attracting attention in the biodiesel industry for its oil. However, the cultivation of J. curcas L. is faced with numerous challenges unlike the cultivation of Ricinus communis L. (2n = 2× = 20), a closely related species. The generation of an intergeneric hybrid between J. curcas L. and R. communis L. was investigated. Intergeneric hybrids were produced by hand crossing. Immature embryos were rescued, in vitro, from the hybrid seeds and cultured on an enriched Murashige and Skoog (MS) medium for a month. The plantlets produced were grown in sterile peat moss in plastic pots and covered with polyethylene for 30 days, after which they were transferred into cement potted soil. The hybridity and the genuineness of the hybrids were successfully confirmed using randomly amplified polymorphic DNA (RAPD) markers. The number of branches, stem diameter, and leaf size of the F1 hybrids were similar to those of J. curcas L. while the plant height was similar to that of R. communis L. Young hybrids were treated with various concentrations (0%, 0.3%, 0.4%, and 0.5%) of colchicine to induce polyploids. The calli (JR6) treated with 0.3% colchicine recorded the highest tetraploid cell percentage (38.89%). A high tetraploid cell percentage (>50%) is significant in overcoming the problem of sterility after hybridization.

Las raíces de las plantas permiten evitar la pérdida del suelo al formar mallas que lo retienen, especialmente en suelos arenosos debido a la poca cohesión de estos sustratos; sin embargo, la literatura técnica sobre la ejecución de las pruebas para caracterizar raíces es escasa, por lo que se requiere documentar su caracterización. Los objetivos de este trabajo fueron documentar y caracterizar las propiedades mecánicas de dos raíces de especies tropicales mediante pruebas de tensión y flexión. Para ello se diseñaron dispositivos especiales para sujetar raíces de Jatropha curcas L. y Ricinus communis L. extraídas de suelos arenosos. Las raíces se sometieron a pruebas de tensión y flexión y se estimaron sus módulos de Young en tensión, así como los esfuerzos máximos de flexión. Los módulos de Young en tensión obtenidos variaron en intervalos de 6.27 MPa a 334 MPa para R. comunis y de 4.56 MPa a 271 MPa para J. curcas, con diámetros entre 0.5 mm y 6.8 mm para ambas especies; en las pruebas de flexión las raíces nunca alcanzaron el punto de ruptura, pero los esfuerzos máximos registrados fueron de 21 MPa y 28 MPa, para Ricinus y Jatropha, respectivamente. Se concluye que las raíces de Jatropha y Ricinus poseen módulos de elasticidad muy bajos, similares a otras raíces de especies herbáceas y arbóreas, con una muy alta flexibilidad y comparables con las propiedades del polietileno de baja densidad.

Em função da variabilidade dos tipos polínicos, sua descrição morfológica constitui suporte para diversas finalidades e estudos. Estão descritas neste trabalho 13 espécies polínicas de interesse apícola, sendo seis da família Euphorbiaceae (Euphorbia milii des Moul., E. pulcherrima Willd. ex Klotzsch, Jatropha curcas L., J. gossypiifolia L., J. multifida L. e Ricinus communis L.) e sete de Lamiaceae (Solenostemon scutellarioides (L.) Codd., Mentha x villosa Huds., Ocimum basilicum L., O. gratissimum L., Plectranthus grandis (L. H. Cramer) R. Willemse, P. neochilus Schlechter e Tetradenia riparia (Hochst.) Codd.). Os grãos foram preparados por acetólise, fotografados e caracterizados quanto a tamanho, forma, aberturas e ornamentação externa. A família Euphorbiaceae mostrou-se euripalinológica com grãos isopolares, de simetria radial, próximos da forma esferoidal, 3-colporados ou atremados (gênero Jatropha), com endoaberturas lalongadas em Euphorbia milii, E. pulcherrima e Ricinus communis, além de exina variando entre fina e espessa, bem como ornamentação reticulada, exceto para Ricinus (psilado). Em Lamiaceae, os grãos apresentaram-se isopolares, com simetria radial, formas que variavam de oblato a prolato, 6-colpados, com exina pouco variável, ornamentação sempre reticulada, sem endoaberturas, caracterizando uma família estenopalinológica.

Cultivation of plants, such as castor bean (Ricinus communis L.) or Jatropha curcas L. is set to increase in future as their seeds are used to extract oil for biofuel production. Ricinus communis seed cake (RSC) and J. curcas seed cake (JSC) were applied to soil cultivated with wheat (Triticum spp. L.) while plant growth and emissions of the greenhouse gases, CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O were monitored. Application of RSC or JSC had no significant effect development of the wheat plants. Emissions of CO<sub>2</sub> and N<sub>2</sub>O increased in soil amended with JSC or RSC, especially when larger amounts were applied, but had no effect on emissions of CH<sub>4</sub>. It was found that application of seed cakes increased emissions of CO<sub>2</sub> and N<sub>2</sub>O, but did not stimulate plant growth.
