Allocation of biomass and photoassimilates in juvenile plants of six Patagonian species in response to five water supply regimes
(Oxford University Press, 2010-08)
Background and Aims The growth-differentiation balance hypothesis (GDBH) states that there is a physiological trade-off between growth and secondary metabolism and predicts a parabolic effect of resource availability (such ...
Structural Modifications of Fructans in Aloe barbadensis Miller (Aloe Vera) Grown under Water Stress
(2016)
Aloe barbadensis Miller (Aloe vera) has a Crassulaceae acid metabolism which grants the plant great tolerance to water restrictions. Carbohydrates such as acemannans and fructans are among the molecules responsible for ...
Nutritional evaluation of diets. Simulation model of digestion and passage of nutrients through the rumen-reticulum
(ELSEVIER SCIENCE BV, 1997)
To evaluate the nutritional behaviour of simple and complex diets provided under different feeding regimes, a stochastic, dynamic and predictive simulation model was developed. Feed fractions, considered in the model were ...
Near-infrared spectroscopy (NIRS) predicts non-structural carbohydrate concentrations in different tissue types of a broad range of tree species
The allocation of non-structural carbohydrates (NSCs) to reserves constitutes an important physiological mechanism associated with tree growth and survival. However, procedures for measuring NSC in plant tissue are expensive ...
Drought tolerance in citrus trees is enhanced by rootstock-dependent changes in root growth and carbohydrate availability
(Pergamon-elsevier Science LtdOxfordInglaterra, 2014)
Leaf carbohydrate metabolism in Malbec grapevines: Combined effects of regulated deficit irrigation and crop load
(Wiley Blackwell Publishing, Inc, 2016-02)
Background and Aims: Regulated deficit irrigation and crop load adjustment are viticultural practices used to improve grape and wine composition. Our objective was to evaluate the combined effect of irrigation and crop ...
Evaluation of in vitro gas production of roughages and their mixtures using the curves subtraction method
(Elsevier B.V., 2004-09-01)
The in vitro gas production of four single roughages and their paired combinations (1:1 on dry matter basis) were evaluated. Two roughage samples (100 mg) per treatment were fermented with ruminal fluid during a 48 h ...

Morphological traits and allocation patterns related to stress-tolerance and seed-yield in wild and domesticated evening primrose (Oenothera L. Onagraceae)
(Elsevier Science, 2011-09)
Wild evening primrose species (Oenothera spp.) native to Argentina, have been suggested as a new crop for irrigated valleys of semi-arid Patagonia. This paper describes patterns of biomass allocation, morphological traits ...
Características morfogenéticas, perdas de nitrogênio por volatilização, reservas orgânicas e sistema radicular do capim-Tanzânia fertilizado com doses de nitrogênio
(Universidade Estadual Paulista (Unesp), 2009-05-08)
O objetivo do trabalho foi estudar as características morfogenéticas e estruturais do capim-Tanzânia, a produção de forragem, as perdas de nitrogênio (N) por volatilização, reservas orgânicas e a avaliação do sistema ...
