“…In addition, it has the advantage of dispensing the need for obtaining hybrid combinations between the parents, and may support the selection strategy for the improvement of oil production in macaúba. For Nugroho et al (2014), genetic improvement has been one of the technologies that have most contributed to the real increase in oil production for some oilseed crops. Thus, the results obtained may provide subsidies for future macaúba harvesting in the municipalities that make up the groups, once the breeder has information about where he can find contrasting macaúba accessions to compose future works and collections of germplasm banks.…”

-The objective of this work was to evaluate the genetic diversity of macaúba (Acrocomia aculeata) accessions from 35 municipalities of the state of Goiás, Brazil, in order to obtain information about the genetic variability and to provide subsidies for the commercial deployment of the culture in the Midwestern region of Brazil. The bunches were harvested with ripe fruits. The following were evaluated: fruit and almond lengths and diameters; the weights of fruits and almonds; the average number of almonds, as well as the oil contents in the almond and in the dehydrated fruit. The parameters that indicated significant contributions to the variability were fruit weight, fruit width, fruit length, and oil content in the almond.Index terms: Acrocomia aculeata, agroenergy, almond quality, biodiesel, divergence, oleaginous seed. Diversidade genética de frutos de macaúba provenientes de 35 municípios de GoiásResumo -O objetivo deste trabalho foi avaliar a diversidade genética de acessos de macaúba (Acrocomia aculeata) provenientes de 35 municípios de Goiás, a fim de obter informações sobre a variabilidade genética e fornecer subsídios para implantação comercial da cultura na região Centro-Oeste. Procedeu-se à colheita dos cachos com frutos maduros. Foram avaliados: os comprimentos e os diâmetros dos frutos e das amêndoas; os pesos dos frutos e das amêndoas; o número médio de amêndoas; bem como os teores de óleo na amêndoa e no fruto desidratado. Os parâmetros que indicaram contribuições significativas para a variabilidade foram peso do fruto, largura do fruto, comprimento do fruto e teor de óleo na amêndoa.Termos para indexação: Acrocomia aculeata, agroenergia, qualidade da amêndoa, biodiesel, divergência, semente oleaginosa.The search for viable alternatives for replacing fossil fuels by biodiesel is a growing concern, especially in relation to global climate change (Pimentel et al., 2016). The macaúba -Acrocomia aculeata (Jacq.) Lodd. ex Mart. -has been used as a raw material in the production of biofuels due to its high content of oil in the fruit, production of various energy residues, besides being a native perennial plant found naturally in almost all the Brazilian territory (Pimentel et al., 2015, Evaristo et al., 2016. The oil of the macaúba mesocarp is rich in oleic acid, and is demanded by both the food and the agroenergy industry (Coimbra & Jorge, 2011).Currently, a large part of macaúba cultivation is restricted to extractive activity, and the few plantations are not yet in full production, and others in some research centers (Oliveira et al., 2016). These research centers in Brazil have been evaluating the genetic potential of different genotypes through quantitative and qualitative analyses as well as physical and chemical analysis of macaúba fruits (Matsimbe et al., 2015).Thus, the macaúba is considered of great interest by the scientific community, especially for its oleaginous property, in relation to the possibility of obtaining genetically superior materials. This results in the identificatio...

“…We were able to develop a severity scale which allowed for the scoring of in vitro‐grown clones and their categorization in terms of resistance and susceptibility to the pathogen (Figure ). Interestingly, despite of the expected somaclonal variation (inherent in the cloning process), which may alter the response of the ramets (Krishna et al, ; Nugroho, Sumertajaya, Wiendi, & Toruan‐Mathius, ; Soh et al, ), a consistency between field observations and the responses of the clones to the in vitro inoculations was observed confirming the validity of the method. As a result, two contrasting ortets were identified, ortet 34, resistant to P. palmivora , and ortet 57, susceptible.…”

Bud rot (BR) disease caused by Phytophthora palmivora is the most devastating disease in oil palm cultivation in America. Oil palms that survived BR epidemics were found in areas highly devastated by the disease; these palms were introduced into Cenipalma's in vitro micropropagation (cloning programme). A severity scale was developed for in vitro palms from five ortets inoculated with two different P. palmivora isolates. Then, eight ortets of Elaeis guineensis and two ortets of the OxG interspecific hybrid were evaluated in two inoculation trials under chamber growth conditions. The clone performance response was consistent with that reported in the field for the corresponding ortets, and two contrasting ortets, one susceptible (ortet 57) and one resistant (ortet 34) were identified. We monitored and compared defence responses to P. palmivora in the contrasting ortets. An increase in reactive oxygen species (ROS) production after inoculation with the pathogen was observed, with higher accumulation of H2O2 in the resistant plants. Catalase (CAT) activity in resistant plants increased after inoculation with the pathogen from 24 hr post‐infection (hpi) and remained high during the observation time. In the susceptible ortets, there was a significant increase on catalase activity only at 48 hpi. Peroxidase (POS) activity increased in clones from both susceptible and resistant ortets, but the increase was much greater in the susceptible ones. Phenylalanine ammonia lyase activity increased in response to inoculation, and these increases were greater in clones of the susceptible ortet than in clones of the resistant ortet.

“…Perbanyakan klonal kelapa sawit melalui kultur in vitro merupakan pendekatan yang berpotensi untuk dikembangkan, mengingat bahan tanaman asal klon mampu menghasilkan tandan buah segar mencapai 20 -25% (Harahap et al, 2010) dan CPO 13% lebih tinggi dibanding kelapa sawit asal perbanyakan biji. Kelemahan perbanyakan kelapa sawit secara in vitro yaitu rendahnya laju embriogenesis (3% -6%) (Kushairi et al, 2010) dan laju embriogenesis yang bervariasi tergantung dari genotipe sumber eksplannya (Nugroho et al, 2014). Pemberian auksin yang berbeda juga menghasilkan respon induksi kalus yang berbeda antar genotipe sumber eksplan (Jayanthi et al, 2015).…”

Analisis kuantitatif fitohormon zeatin dibutuhkan untuk mengetahui korelasi antara respon pembentukan kalus maupun embrio dengan keberadaan zeatin itu sendiri pada jaringan eksplan serta interaksi antara zeatin yang terdapat pada jaringan eksplan dengan zat pengatur tumbuh sintetis yang ditambahkan pada media kultur in vitro kelapa sawit. Penelitian ini dilakukan untuk memperoleh metode analisis kandungan zeatin yang mudah dan cepat untuk direproduksi sehingga dapat diaplikasikan pada kajian-kajian penelitian fitohormon, terutama zeatin. Analisis dilakukan menggunakan ultra-high performance liquid chromatography (UHPLC) dengan kolom C18 dan fase gerak 100% metanol (MeOH) secara isokratik serta laju alir 0.2 mL/menit dengan detektor UV λ = 280 nm. Eksplan yang dianalisis berasal dari individu yang mewakili varietas La Me, Avros, PPKS 239 dan Simalungun. Hasil uji kesesuaian sistem menunjukkan bahwa metode memenuhi syarat untuk digunakan untuk analisis dengan nilai rerata standar deviasi parameter RSD ≤ 2. Validasi metode memberikan hasil kurva kalibrasi dengan nilai koefisien determinasi r2 = 0,9996 dan presisi instrumen dan metode dengan standar deviasi relatif masing-masing sebesar 0,56 dan 1,03. Diperoleh nilai LoD dan LoQ masing-masing sebesar 2,457 ppm dan 7,446 ppm.
