“…The diameter at the soil level is a variable widely used to describe the initial growth behavior of a tree species in response to the climatic variations of a given region (SCHNEIDER et al, 2014). While evaluating this variable's increment, a behavioral difference was perceived between the stands of 2016 and 2017.…”

This study compares the impact of five meteorological variables on the diametric growth of Pinus caribaea var. hondurensis Barrett & Golfari in Vilhena, Rondônia. One thousand nine hundred sixty-eight trees were evaluated and classified at different ages: 600 trees were one year old; 600 trees were two years old; 768 trees were 13 years. The diameter measurement at the soil level (SL) was conducted in young stands between one and two years old. In the stand with 13 years old, the diameter was measured at 1.3 m (DCH). Using a Pressler borer, 50 increment cores were removed at DCH to measure the tree rings in LINTAB™ 6. The diametric growth was evaluated through the Periodic Increment (PI) for young stands and Current Annual Increment (CAI) for adult stands. The following variables were considered: average temperature (°C), precipitation (mm), solar radiation (Kj m-²), real evapotranspiration (mm), and maximum relative humidity (%). The Pearson Correlation Coefficient (r) proposed by Callegari-Jacques and the coefficient of variation (CV%) were used to establish the relationship between growth and meteorological variables. For young stands, the variables with higher positive correlation were real evapotranspiration and maximum relative humidity. However, the variable with a higher positive correlation in adult stands was average temperature, demonstrating a strong correlation until the sixth year of the species.

“…Por lo tanto, el uso de especies nativas del sitio a recuperar se convierte en una buena alternativa para acelerar el proceso de restauración de áreas degradadas y el mantenimiento de la biodiversidad ambiental. De acuerdo con Schneider et al (2014), este tipo de planta presenta una gran rusticidad y agresividad para competir con otras especies y proteger el suelo rápidamente.…”

“…En la recuperación de áreas degradadas, el método de revegetación del suelo es una importante técnica cuyo objetivo promueve el retorno de las condiciones deseables al ambiente, mediante del uso de especies con características de acelerado y eficiente desarrollo en áreas fragilizadas (Rovedder et al 2010, Schneider et al 2014. En este contexto, la especie de Butia lallemantii Deble et Marchiori presenta características relevantes para la recuperación de esas áreas dañadas, debido su ocurrencia natural y exclusiva en campos de suelos arenosos y en las elevaciones areníticas de diversos municipios del suroeste del RS (Soares et al 2014).…”

Butia lallemantii is endemic from sandy soils in the state of Rio Grande do Sul (RS). Sandblasted soils stand out for fragile characteristics of low fertility, water availability and intense sand displacement. However, studies on planting techniques, use of fertilizers and alternative products that may favor the establishment of plants in these soils are lacking. Therefore, the objective of the study was to evaluate the survival and leaf appearance of the B. lallemantii plants established by the revegetation method in sandy soil, with the increase of mineral fertilizer and hydroretentor polymer, as well as monitoring the movement of sand particles. The plants were collected in Alegrete / RS, classified in stipe diameter and kept in substrate (soil, animal waste and rice husk, 1:1:1) for eight months. In field plantation, the doses of NPK and hydrogel were randomly placed between five graded rules in the soil, for periodic sand displacement readings. Survival, appearance of live leaves and sand displacement were evaluated monthly, with a randomized block design (100 seedlings/block). Results showed higher survival and presence of living leaves in the plants of block one, and average displacement of sand in the spring period. Therefore, plants of larger stipe diameter class show higher potential for survival and larger number of live leaves, in addition, sand displacement mainly happens during spring.

Este trabalho teve como objetivo ajustar duas equações volumétricas, sendo uma em função do diâmetro e altura e outra em função da idade, para Pinus taeda L. no município de Enéas Marques, Paraná. Para tanto, a coleta de dados consistiu na realização de cubagem rigorosa e análise completa de tronco em 16 árvores. Posteriormente, realizou-se a modelagem com o uso de sete modelos volumétricos em função de diâmetro e altura e cinco modelos em função da idade. As equações de volume que melhor se ajustaram aos dados .
