Photosyn Thesis

Elaeis guineensis palms and its interspecific hybrid (E. oleifera x E. guineensis) were planted in 2004 in the Cuernavaca farm of Unipalma S.A., located in the municipality of Paratebueno (Cundinamarca, Colombia). The palms were planted in two fields: Mecasaragua and Aurora. The first field has never been irrigated, and the second one (Aurora) has always been flood-irrigated during the dry season according to the parameters of the plantation. In this study, physiological parameters (gas exchange and water potential) were assessed in three seasons of the year 2013 (dry season, dry-to-wet transition season and wet season). Significant gas exchange differences were found among the seasons in the field with no irrigation (Mecasaragua). Likewise, differences between the genetic materials were observed during the dry season. For example, the photosyn thesis decreased by 75% compared with the palms planted in the irrigated field. No differences among seasons or materials were found in the irrigated field (Aurora). E. guineensis palms were more sensitive to water stress compared with the OxG interspecific hybrid. Both genetic materials responded rapidly to the first rains by leveling their photosynthetic rates and demonstrated an excellent capacity to recover from water stress.

African Oil Palm

The oil palm (E. guineensis ) is the African origin and the world's leading source of vegetable oil. The interspecific hybridization of the African oil palm (E. guineensis) with American oil palm (E. oleifera) aims to improve resistance to diseases, to improve oil quality and lower plant height. EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária, Brazilian Corporation of Agricultural Research) has developed the first Brazilian interspecific hybrid cultivar (HIE) between American oil palm and African oil palm. The procedures adopted for commercial seed germination assessment have shown an average germination rate of 32%. The objective of this work was to assess the effect of the period of heat treatment and seed water content that are ideal for breaking dormancy and obtaining maximum germination. A completely randomized design was adopted, in a 4 x 3 factorial design, with four ranges of moisture contents: 18-19; 19-20; 20-21 and 21-22%, and three periods of heat treatment: 55, 75 and 100 days, with three replicates of 500 seeds. The percentage of germination, the first count and the germination speed index were assessed. To break dormancy and germination, the hybrids seeds of HIE, oleifera versus guineensis, should have their water content adjusted to values between 19 and 22%, and be subjected to heat treatment at a temperature of 39 ± + 1 ºC and relative humidity of approximately 75% for 75 days.

Oil palm is the most productive and efficient oilseed crop in the world. Oil palm is planted in various geographical areas, where the frequency of extreme weather events is expected to increase because of climate change. The characterization of the response of oil palm cultivars to climatic conditions will allow identifying sources of tolerance to different types of stress caused by climate change, leading to the determination of the best genotype x environment relationships. The physiological responses, oil quality and yield of 11, six-year-old commercial oil palm cultivars with different origins were evaluated in two periods of contrasting climate conditions (rainy and dry seasons between the years 2008 and 2010). We found that the first impact of a period with water deficit was the reduction on gas exchange of all cultivars. Photosynthesis fell between 25% to 40% and transpiration decreased between 10% and 50%. During the dry season, leaf sugar concentration increased respect to the rainy season between 14% to 114%, and certain cultivars showed up to 27% higher photosynthetic water use efficiency. This variation could be due to the genetics of different cultivars. No significant differences were observed between the seasons in terms of oil quality. In general, changes in oil palm physiology observed in response to water deficit were related to the ability of the palm to adapt and survive periods of drought stress. The cultivars evaluated showed a good response to dry periods, with the IRHO being the most outstanding at each evaluated season .

Aiming at generating a comprehensive genomic database on Elaeis spp., our group is leading several R&D initiatives with Elaeis guineensis (African oil palm) and Elaeis oleifera (American oil palm), including the whole-genome sequencing of the last. Genome size estimates currently available for this genus are controversial, as they indicate that American oil palm genome is about half the size of the African oil palm genome and that the genome of the interspecific hybrid is bigger than both the parental species genomes. We estimated the genome size of three E. guineensis genotypes, five E. oleifera genotypes, and two interspecific hybrids genotypes. On average, the genome size of E. guineensis is 4.32 ± 0.173 pg, while that of E. oleifera is 4.43 ± 0.018 pg. This indicates that both genomes are similar in size, even though E. oleifera is in fact bigger. As expected, the hybrid genome size is around the average of the two genomes, 4.40 ± 0.016 pg. Additionally, we demonstrate that both species present around 38% of GC content. As our results contradict the currently available data on Elaeis spp. genome sizes, we propose that the actual genome size of the Elaeis species is around 4 pg and that American oil palm possesses a larger genome than African oil palm.

An Attempt to combine the superior traits of Elaeis oleifera and Elaeis guineensis have been done through an interspecific hybrid cross and followed by pseudo-backcross 1 (pBC1). Observation of vegetative morphology and bunch components are presented in this paper. Two populations of pBC1 E. oleifera from the Suriname and Brazil origin were planted in 1990, 1993, 1995, and 2005, and were intensively observed for vegetative morphological properties and bunch components in November 2016 to February 2018. The results showed that almost all the individuals of pBC1 grew upright such as E. guineensis, no longer growing horizontally like the wild E. oleifera and the interspecific hybrid populations. The datas showed that the Suriname population plant architecture are compact or smaller than the Brazilian origin including the height increment and the size of the stem, the frond architecture and its components. Similarly, the bunch components show that the pBC1 Brazil is slightly superior to Suriname pBC1.

El objetivo de este estudio fue realizar un análisis comparativo de las características físicas y químicas de racimos de genotipos de Elaeis oleifera y de sus híbridos interespecíficos OxG con Elaeis guineensis, determinando los componentes y el potencial del aceite del racimo, y la calidad de los aceites, analizando el contenido de ácidos grasos, vitamina E y carotenos. En el estudio se utilizaron racimos provenientes de inflorescencias sin polinización asistida con la presencia perimetral de E. guineensis. Se utilizó un diseño experimental completamente al azar con tres unidades experimentales, cada una conformada por tres racimos. Los mayores cuajados del fruto se encontraron en el genotipo de E. oleifera Sinú (76,53 %) y el híbrido OxG II (72,64 %). Los potenciales de extracción de aceite fueron superiores en los materiales híbridos OxG destacándose el II (20,82 %). Las palmas E. oleifera presentaron mejores perfiles de ácidos grasos, destacándose los materiales del genotipo Sinú (79,1 % de ácidos grasos insaturados) y los del híbrido II (70,2 %). Para el contenido de vitamina E se confirmó la alta calidad del aceite de los materiales de E. oleifera, sobresaliendo el genotipo Coarí (1.006,7 ppm) y el híbrido II (1.549,6 ppm); el material del genotipo Sinú registró el mayor contenido de carotenos totales (1.524,7 ppm).
