1. Leaf area estimation with nondestructive method in cassava
ABSTRACT The objective of this study was to create a single mathematical equation able to estimate the leaf area of different cassava cultivars from one lineal dimension without destroying any plant tissue. Two hundred leaves per cultivar from ten cultivars were used to calibrate the model and more than one hundred leaves per cultivar were used to test its p

2. Interaction between growth strategies and phosphorus use efficiency in grasses from South America natural grasslands
ABSTRACT South American natural grasslands are composed of several species with different growth strategies, with variations in specific leaf area (SLA), leaf dry matter content (LDMC), specific root length (SRL) and specific root area (SRA). The objective of this study was characterizing in grasses cultivated with different levels of phosphorus (P) in the s

3. 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

4. Agronomic performance of white oats cultivated under fertigation with treated sewage effluent and definition of critical limits of Normalized Difference Vegetation Index
ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.

5. Crescimento e partição de massa seca em plantas jovens de amburana (Amburana cearensis (Fr. All.) AC Smith) e de umbuzeiro (Spondias tuberosa Arr. Cam.)
Resumo As espécies amburana (Amburana cearensis (Fr. All.) A. C. Smith) e o umbuzeiro (Spondias tuberosa Arr. Cam.) possuem adaptações fisiológicas e morfológicas às condições climáticas do bioma caatinga e atualmente estão sob ameaça de extinção. Objetivou-se com a realização deste trabalho caracterizar a partição de fotoassimilados das mud

6. Residues of Invasive Forage Species Inhibits the Growth of Caryocar brasiliense
RESUMO: O crescimento de mudas de espécies nativas pode ser afetado por substâncias alelopáticas liberadas por espécies forrageiras invasivas principalmente em áreas de recomposição natural. Objetivou-se nesta pesquisa avaliar as características de crescimento do pequizeiro influenciadas por concentrações de resíduos vegetais das espécies forrage

7. Growth of tomato seedlings in substrates containing a nanocomposite hydrogel with calcium montmorillonite (NC-MMt)
RESUMO O uso correto de hidrogéis em determinadas situações pode aumentar as taxas de sobrevivência das plântulas, seu crescimento e a capacidade de retenção de água do meio de cultivo. Uma técnica para a produção de um hidrogel nanocompósito usando montmorilonita de cálcio (NC-MMt) foi desenvolvida recentemente. No entanto, resultados da pesqui

8. Phenotypic Plasticity of Pimenta pseudocaryophyllus (Gomes) Landrum Under Different Light Conditions
ABSTRACT The heterogeneous light pattern in forest environments leads to specific morphological and physiological responses. However, anthropogenic pressures in areas such as Atlantic Forest and Cerrado are modifying the light availability, and consequently the forest community composition. The aim of this study was to investigate the plasticity of forest sp

9. Elevated atmospheric CO2 concentration improves water use efficiency and growth of a widespread Cerrado tree species even under soil water deficit
ABSTRACT Changes in atmospheric CO2 levels are accompanied by ecological interactions involving other environmental factors, such as drought, which can severely alter the water balance of plants, thereby influencing sap flow, gas exchange, and plant growth. The objective of this study was to evaluate the water use economy, leaf gas exchange, and growth of yo

11. Growth rates and yields of cassava at different planting dates in a tropical savanna climate
ABSTRACT: Details on growth and yield for cassava planted on different dates are useful for determining suitable genotypes for particular growing seasons. Our aim was to study growth and yield of cassava planted on different dates. Four cassava genotypes (Kasetsart 50, Rayong 9, Rayong 11 and CMR38-125-77) were evaluated using a randomized complete block des

12. O vigor da planta altera a densidade de galhas em populações de Baccharis longiattenuata (Asteraceae) sob distintas condições de solo?
Resumo A hipótese do vigor da planta sugere que plantas mais vigorosas suportam maior densidade de galhas. Este estudo avaliou tal hipótese utilizando o sistema ácaro-Baccharis longiattenuata em duas populações de restinga sob condições ambientais distintas. As medidas de vigor incluíram: altura e diâmetro do caule, volume e área da copa, número d
