1. Growth analysis of potato genotypes
ABSTRACT Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 cro

2. Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonizatio

3. Evaluation yield and genetically factors in different cultivars of gladiolus
Abstract In order to suggest the best cultivars of gladiolus to grow in moderate regions of Iran, an experiment was carried out in a complete randomized block design in three replications with five cultivars of Gladiolus grandiflorus (‘Oscar’, ‘Red Advance’, ‘White Prosperity’, ‘Rose Supreme’ and ‘Lemon Drop’) at the ornamental plants res

4. EFFECTS OF SEASONAL AIR TEMPERATURES AND LIGHT ON LEAF TRAITS AT ATLANTIC MONTANE FOREST, BRAZILIAN SOUTHEAST
ABSTRACT Seasonal variation of temperature could place physiological constraints on the distribution and performance of tropical forest plants, associated with light and water availability. A simple way to assess the relationship between temperature and plant physiology is through the characterization of leaf traits. The main aim of this study was to evaluat

5. A revision and morphological analysis of the Uruguayan species of Stevia (Compositae, Eupatorieae)
Abstract A revision and a morphological analysis of the Uruguayan species of Stevia (Compositae, Eupatorieae) were performed. Leaf, inflorescence, pubescence and pappus traits were identified as key to separate species. Stevia entreriensis, S. entreriensis var. minor, and Dissothrix hassleriana were considered synonyms of S. hirsuta, and S. ophryodonta and S

6. Morphology of yellow passion fruit seedlings submitted to triazole induced growth inhibition
RESUMO A restrição do vigor vegetativo de mudas pode ser uma estratégia para otimização da modulação frente à estresses bióticos e abióticos após o transplantio. O objetivo desse estudo foi verificar se os parâmetros morfológicos de mudas de maracujazeiro amarelo (Passiflora edulis) são afetados pela restrição do crescimento com aplicação d

7. Adaptive morphoanatomy and ecophysiology of Billbergia euphemiae, a hemiepiphyte Bromeliaceae
Resumo Habitats com pressões seletivas diferentes exercem pressões adaptativas que podem levar indivíduos de uma mesma espécie a apresentar diferentes estratégias de vida para sua sobrevivência. O objetivo desse estudo foi analisar características funcionais para identificação de estratégias ecológicas adaptativas relacionadas às fases de vida te

8. Potential of pepper plant accessions for ornamental purposes using diallel analysis
Abstract: The genus Capsicum is cultivated in various parts of the world, with C. annuum showing high diversity and potential for ornamental purposes and genetic improvement. The aim of this work was to evaluate the combining ability and heterosis of seedling and plant traits in accessions of ornamental pepper and their hybrids. Seven accessions of C. annuum

9. Reaction of advanced inbred lines of Habanero pepper to Ralstonia pseudosolanacearum and Phytophthora capsici
RESUMO A pimenta Habanero é popular no mercado internacional e começa a despertar maior interesse no nacional, porém poucas cultivares adaptadas às condições edafoclimáticas e com resistência às principais doenças como murcha bacteriana (MB) e murcha de fitóftora (MF), causadas respectivamente por Ralstonia pseudosolanacearum (RP) e Phytophthora c

10. Leaf structural traits of three species of Qualea Mart. (Vochysiaceae) in a cerradão area in the Cerrado-Amazonian Forest transition
Resumo Qualea é um gênero comumente encontrado em diferentes fisionomias do cerrado brasileiro, crescendo em ecossistemas abertos até áreas florestais fechadas, sujeitos à alta irradiância, incêndios, baixa disponibilidade de nutrientes e deficit hídrico sazonal. Comparam-se aqui, atributos estruturais foliares de Qualea grandiflora Mart., Qualea mul

11. Respostas funcionais foliares de plantas jovens de Hevea brasiliensis submetidas à deficiência hídrica e à reidratação
Resumo A deficiência hídrica é considerada um fator que produz danos significativos durante o período de estabelecimento e de crescimento dos plantios. O objetivo deste estudo foi investigar características morfofisiológicas e bioquímicas de folhas de mudas de seringueira em resposta à deficiência hídrica e, posterior, reidratação. Plantas jovens

12. Functional patterns of tree communities in natural Araucaria forests and old monoculture conifer plantations
ABSTRACT A functional perspective of tree communities is helpful for understanding forest dynamics, especially vegetation recovery after other land uses. Knowledge about ecological filters and survival strategies of trees are also important for the restoration of degraded areas. This study aimed to evaluate the functional composition and structure of adult a
