The purpose of this work was to estimate genetic parameters and selection gain of Pinus caribaea var. hondurensis progeny trial for wood and resin production as well as correlation between them. Experiment was established in complete lattice square 10 x 10 (triple), 100 treatments, 10 plants per plot, 3 m x 3 m spacing. Twelve years after planting the trial had thinned considerably leaving six plants per plot. Twenty-seven years after planting height, diameter at breast height (dbh) and resin production were measured. Deviance analysis, genetic parameter estimates, selection expected gain, genetic and phenotypic correlation were based on REML/BLUP method. Significant phenotypic differences were observed among and within families for all traits. The thinning at 12 years after planting, contributed positively to dbh increase and resin production, with an average of 30.60 cm and 4.83 kg tree-1year-1. The individual narrow sense heritability ranged from 0.25 to 0.38 for dbh and volume. Genetic and phenotypic correlation between growth traits were positive, and significant. Therefore, different selection strategies will be proposed separately for both traits (resin and wood). The selection gains were significant, especially with 10 % selection intensity (individual selection) for dbh (7.53 %) and resin (13.49 %). The trial has had good performance for growth, resin and genetic variability to support the next breeding generation. |

In the shift towards sustainable development, there is increasing interest in the isolation of cellulose nanomaterials using enzyme-mediated strategies that are more environmentally friendly. The principles of systematic mapping were used here to conduct a literature review covering the most recent research on cellulose nanomaterials whose production processes included the use of enzymes, identifying trends and gaps in the literature. results evidenced a significant increase in the publications related to nanocellulose production using enzymes, especially in the last eight years (2013?2021). The feedstocks most used were derived from hardwoods and agro-industrial residues. The commonest enzymes employed were commercial cellulase and endoglucanase rich preparations. Importantly, there is still no commercially available enzymatic preparation specifically designed for nanocellulose production. Moreover, this systematic mapping showed that nanocelluloses have frequently been used in film preparation and as reinforcement agents. These data should assist researchers in future studies, while synthesizing information relevant to decision-making. |
