13. ORNAMENTAL PEPPER ON REFLECTIVE BENCH UNDER PROTECTED ENVIRONMENTS
ABSTRACT Plant ambiance studies the environmental condition favorable to plant growth at the initial stage of seedlings or the complete production cycle. This study aimed to evaluate the cultivation of the ornamental pepper ‘Pyramid’ under protected environments and growing benches with and without reflective material. The protected environments consiste

14. Maintenance of wetland plant communities: the role of the seed bank in regeneration of native plants
ABSTRACT Exotic grasses have been introduced into wetlands and can compete with native plants due to their high tolerance of flood and dry periods. Flooding can facilitate seed dispersal of exotic species and reduce the diversity of native species. We compared two grasslands to assess whether seed banks can maintain the diversity of native plants in wetlands

15. Biomass production of the aquatic macrophyte Ceratopteris pteridoides (Hook.) Hieron (Pteridaceae) in nutrient addition treatments
ABSTRACT Aquatic macrophytes are a key group in flooded areas due to their high primary productivity, and several species present in the Amazonian floodplains have potential for human food use. This study evaluated biomass production and nutrient levels in fronds of Ceratopteris pteridoides (Pteridaceae), under the following nutritional treatments: (T1) arte

16. Implications of global climate change for the development and ecological interactions between two key Amazonian aquatic macrophytes
ABSTRACT Amazon wetlands are among the most vulnerable ecosystem to be impacted by climate change, which may increase the frequency of extreme droughts and floods. We used Eichhornia crassipes and Pistia stratiotes, two abundant aquatic plants in the Amazon floodplains, to evaluate the effects of combined temperature and [CO2] increase on growth, physiology

17. Breaking the misconception of a dry and lifeless semiarid region: the diversity and distribution of aquatic flora in wetlands of the Brazilian Northeast
ABSTRACT The semiarid region of northeastern Brazil possesses a set of wetlands characterized by hydrographic basins with deficient drainage networks, a few large and permanent lotic systems and several permanent and temporary lagoons. Aquatic plants are widely distributed in these wetlands and the present study aims to determine if those of Ceará state hav

18. Spontaneous vegetative propagules differentiation in Bowdichia virgilioides seedlings maintained at MS basal medium
ABSTRACT Bowdichia virgilioides Kunth is a medium size tree used in folk medicine and in furniture manufacturing which makes it a target of extractive processes. The aim of this work was to evaluate the endogenous content of polyamines, amino acids, and sugars in seedlings of Bowdichia virgilioides that presented or not the development of spontaneously diffe

19. GROWTH PROMOTION OF GENETICALLY IMPROVED Pinus taeda SEEDLINGS BY INOCULATION WITH SPECIES OF Bacillus.
ABSTRACT This study was carried on evaluating effects of inoculation with Bacillus species and generations of genetically improved seeds on Pinus taeda growth in nursery conditions. Two experiments, based on distinct inoculation methods (sowing and post-emergence) were performed under a 3 x 2 factorial, completely randomized block design (3 levels of inocula

20. WATER-RETAINING POLYMER MITIGATES THE WATER DEFICIT IN Schinus terebinthifolia: PHOTOSYNTHETIC METABOLISM AND INITIAL GROWTH
ABSTRACT The use of water-retaining polymer (hydrogel) can mitigate the damage to the photosynthetic apparatus and increase the robustness of young plants under water deficit conditions. Thus, the aim of this study was to evaluate the effect of water-retaining polymer on the morphophysiological aspects of Schinus terebinthifolia Raddi submitted to water defi

21. Effect of high temperature and recovery from stress on crop–weed interaction
ABSTRACT Biotic and abiotic stresses, either individually or in combination, may affect soybean growth and development negatively, besides competitiveness with weeds. This study aimed at evaluating the effect of heat stress and plant recovery on crop–weed interaction by analyzing growth variables. Experiments were set up as replacement series of soybean wi

22. Infusion of Chenopodium ambrosioides consumed by rabbits: effects on carcass, meat and burger quality
Abstract Plants with high levels of antioxidant compounds have been used to feed animals and increase stability of their meat and meat products. The objective of this study was to evaluate the effects of Chenopodium ambrosioides infusion on carcass, meat and burger quality. Rabbits were assigned to each treatment (0, 5 or 10 g.L-1 of Chenopodium ambrosioides

23. GROWTH OF ORNAMENTAL PEPPER IN COLORED CONTAINERS UNDER PROTECTED ENVIRONMENTS
ABSTRACT Ornamental pepper plants produced in containers under protected environments have high added value. We carried out research with an aim to evaluate the growth and development of ornamental pepper in containers of different colors under two protected environments, both with thermal-reflective screens under a polyethylene film: one with 18–22 % shad

24. Exogenous gibberellin and cytokinin in a novel system for in vitro germination and development of African iris (Dietes bicolor)
ABSTRACT The availability of reliable and reproducible micropropagation systems is a decisive step to successfully propagate plant species with slow growth and low germination rate. The effect was investigated of gibberellin (GA) and cytokinin (CK) in the in vitro germination and development of Dietes bicolor (Steud.) Sweet ex Klatt. Seeds were inoculated in
