Testing individual inter-annual variations in flower production by means of retrospective analysis of meristem allocation in two tree species
(Springer, 2016-12)
High inter-annual variations in flower and seed production have been frequently reported for wind-pollinated tree species. Such variations have been generally studied from a population perspective. The present study focuses ...
Growth dynamics of the branching system in grasses: An architec noture-based methodology for quantitative evaluation applied to two genotypes of Paspalum vaginatum
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2019-12-20)
The aerial growth dynamics of the shoots of the widespread turfgrass Paspalum vaginatum was studied. With the aim of identifying quantitative differential features between two genotypes, plants were cultivated outdoors in ...
Spatial distribution of phlorotannins and its relationship with photosynthetic UV tolerance and allocation of storage carbohydrates in blades of the kelp Lessonia spicata
(2016)
The action of an intercalary meristem in the fronds determines the growth patterns of the sub-Antarctic kelp Lessonia spicata, which result in gradients in physiological activity and tissue composition. In this study, the ...
Alocação de fotoassimilados marcados e relação fonte-dreno em figueiras cv. Roxo de Valinhos. 1. Relação fonte e dreno
(2011-07-01)
The work aimed at evaluating the photosynthates allocation using the stable carbon 13 isotope as marker, as well as evaluating the source-sink dynamics in the different organs in Ficus carica L. plants in the reproductive ...
Alocação de fotoassimilados marcados e relação fonte-dreno em figueiras cv. Roxo de Valinhos. 2. Tempo de alocação
(2011-07-01)
The work evaluated the translocation and allocation period of the photosynthates, using the carbon-13 stable marker, in Ficus carica L. cv. Roxo de Valinhos plants in the reproductive stage. A fig tree leaf considered adult ...

Ecological significance of determinate primary root growth: inter- and intra-specific differences in two species of Gymnocalycium (Cactaceae) along elevation gradients
(Elsevier Gmbh, 2018-11)
Determinate primary root growth in Cactaceae has been interpreted as an adaptation to dry environments. However, little information is available regarding ecological patterns of this process. Our research question was ...
Flower and seed production as affected by axis category and shoot size in two patagonian nothofagus species
(National Research Council Canada-NRC Research Press, 2012-04-21)
Flower distribution within the tree crown may affect both pollination dynamics and the costs of flowering on tree growth. For Nothofagus obliqua (Mirb.) Oerst. and Nothofagus nervosa (Phil.) Krasser, the production of ...
