Efeitos do fósforo do solo no desenvolvimento inicial de Genipa americana L.
(2003-12-01)
A greenhouse experiment was carried out to evaluate the effects of soil phosphorus in the development of plants of Genipa americana L. Five doses of P (0, 50, 100, 200, and 400 mg dm -3) were applied in pots with 10 dm 3 ...
Estimativas de biomassa acima do solo de Piper mikanianum por métodos indiretos
(Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências Rurais, 2021-05-28)
This study aimed to evaluate regression models to estimate the biomass of rush and leaves of Piper mikanianum. For this purpose, in the municipality of Silveira Martins - RS, in secondary formations of the Seasonal Deciduous ...
A comparison between traditional ordinary least-squares regression and three methods for enforcing additivity in biomass equations using a sample of Pinus radiata trees
(Scion, 2020)
Background: Additivity has long been recognised as a desirable property of systems of equations to predict the biomass of components and the whole tree. However, most tree biomass studies report biomass equations fitted ...
Wood productivity of Prosopis flexuosa D.C. woodlands in the central Monte: Influence of population structure and tree-growth habit
(Academic Press Ltd - Elsevier Science Ltd, 2011-04)
A balance between forest production and protection is hard to achieve in arid zones due to their low potential for wood production. Prosopis flexuosa woodlands are the major woody formations in the Monte desert and are ...
Close-spaced plant arrangement optimizes castor biomass and seed yields in tropical fall–winter conditions
(2022-01-01)
The high seed yield and optimum harvesting of short-height castor (Ricinus communis L.) genotypes have enabled its large-scale cultivation and introduction in the Brazilian cropping systems. Thus, studies to optimize plant ...
Elephant grass leaves have lower recalcitrance to acid pretreatment than stems, with higher potential for ethanol production
(2018-01-01)
Elephant grass is gaining attention among lignocellulosic materials due to its high growth potential, biomass yield, limited requirement for cultivation land and high rates of carbon dioxide absorption. Here was investigate ...
Combining taper and basic wood density equations for estimating stem biomass of the Populus x canadensis I - 488 varietyCombinación de funciones de ahusamiento y densidad básica de la madera para la estimación de la biomasa fustal de Populus x canadensis variedad I - 488

Critérios para a amostragem de lianas: comparação e estimativa da abundância e biomassa de lianas no Cerrado
(Univ Federal Vicosa, 2013-11-01)
Lianas play a key role in many tropical forests ecosystems, contributing to community abundance, diversity and structure. Techniques to census lianas and estimate biomass have been used mainly in tropical forests. The aim ...
