Resumo: Nos últimos anos, a produção mundial do óleo da palma ultrapassou a produção de óleos vegetais de outras culturas, como a soja. O Brasil tem áreas com grande potencial para produção da palma de óleo, dentre essas, os plantios podem ser feitos em áreas degradadas, proporcionando condições para aumento da taxa de emprego e renda na zona rural. Para o alcance de elevada produtividade, é essencial conhecer os mecanismos fisiológicos e parâmetros de qualidade do óleo, especialmente em situações de estresse hídrico. Nesse sentido, foram avaliadas características de qualidade do óleo de palma produzido sob as condições de estresse hídrico, bem como a Fluorescência da clorofila A em folíolos que constituem as folhas adultas das plantas de óleo de palma cultivar BRS C2501, durante o período seco da região de transição Cerrado-Amazônia, que se encontravam sob variação do nível de água por meio da irrigação (0%, 20%, 40%, 60% e 80%). | Abstract: In recent years, world production of palm oil has surpassed the production of vegetable oils from other crops, such as soybeans.

To achieve high productivity, it is essential to know the physiological mechanisms and oil quality parameters, especially in situations of water stress. In this sense, quality characteristics of palm oil produced under water stress conditions were evaluated, as well as chlorophyll A fluorescence in leaflets that constitute the adult leaves of palm oil plants cultivar BRS C2501, during the dry season in the region. of Cerrado-Amazon transition, which were under water level variation through irrigation (0%, 20%, 40%, 60% and 80%).

The Agave genus is composed of about 200 species, but the cultivation of sisal for fiber production in Brazil is restricted to two species: Agave sisalana and Agave fourcroydes, both have several accessions with wide variability. The collection of Agave of Embrapa has 37 accessions maintained in situ and periodically evaluated agronomical traits. Most of these accessions have phenotypic similarities, although they differ in fiber quality, which are widely used for commercial purposes. The identification of promising accesses contributes to the advance in improvement works, focusing on commercial indication. In order to estimate the genetic divergence of this collection, a cluster analyses was performed based on Inter-Simple Sequence Repeat (ISSR) markers and phenotypic traits. Genomic DNA from these accessions were used in polymerase chain reaction (PCR) with thirty ISSR oligonucleotides. For phenotypic characterization, twelve descriptors were adopted based on morphological and agronomic data. The Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and Tocher multivariate methods were adopted. Thirteen groups were formed by the Tocher Method and six by UPGMA; however UPGMA method was more representative in the group formation. The comparison of the band patterns among accessions derived from the shoots showed that genetic variability is generated during asexual reproduction in these plants. The four lines generated from Tatui were the most divergent accessions. These plants are tallest, with higher mass values of fresh and dry mucilage, fresh and dry fiber mass, fiber length and presence of spines at the edges. The accessions from Instituto Agronômico de Campinas (IAC) showed the lowest genetic distances, indicating a possible narrow genetic base and high kinship degree. The crossings between H-RN, H-Kenya, H-400 fls, and H-11648 with Tatuí 1, 2, 3, and 4 can be a valorous strategy to broadening genetic diversity among commercial and native sisal germplasm.
