1. INTERFERENCE OF OPERATING SPEED AND PHYSICAL PROPERTIES OF GRANULATED FERTILIZERS WITH THEIR DEPOSITION
ABSTRACT Uniformity in the deposition of granulated fertilizers in the seed furrow is essential for crop development and productivity. Quantitative (dose and flow) and qualitative factors (segregation and formulation) influence granulated fertilizer distribution throughout its application. This experiment aimed to compare the deposition of two granulated fer

2. Population structure, diametric distribution and use of Commiphora leptopholoeos (Mart.) JB Gillett in arboreal Caatinga
ABSTRACT The objective of this work was to characterize the population structure, analyze the spatial distribution pattern and identify the potential use of the Commiphora leptopholoeos in the Contendas do Sincorá National Forest, BA. Thus, three disjoint transects of 40 x 160 m were installed for the phytosociological study and spatial distribution and sub

3. Quality of Stylosanthes Campo Grande seeds coated with different materials
ABSTRACT The seed coating technique adds value to the seeds. This technique allows changing the seed size and shape, facilitating sowing, and also the application of essential nutrients to the good development of the plant in the post-germination phases. Therefore, the objective of this work was to evaluate the physical and physiological characteristics of S

4. Gold Nanorods Capped with Different Ammonium Bromide Salts on the Catalytic Chemical Reduction of p-Nitrophenol
It is known that the reactivity of the nanocatalytic systems is related to the particle size and shape and also to the features of the capping agents on the nanostructures. In this study, gold nanorods (AuNRs) were synthesized by the seed-mediated method using different tetra-alkylammonium bromide salts as capping agents, that are, cetyltrimethylammonium (CT

8. MORPHOMETRIC ANALYSIS OF FRUITS AND SEEDS OF Annona crassiflora Mart. (ANNONACEAE) FROM CENTRAL BRAZIL
RESUMO Com a existente redução da cobertura vegetal do Cerrado, diversas espécies arbóreas têm suas áreas de ocorrência diminuídas e como consequência perdem parte de sua diversidade genética. Para contrapor este cenário faz-se necessário conhecer a diversidade genética afim de embasar projetos e medidas práticas de conservação. Assim, este t

9. Establishment and optimization of a hydroponic system for root morphological and nutritional analysis of citrus
ABSTRACT The hydroponic growth system is a convenient platform for studying whole plant physiology, especially for root morphological and nutritional analysis. However, we found that most hydroponic systems described in the literature are not suitable for citrus plants. In this study, a hydroponic system for citrus was designed, comprising three principal co

12. Seed Germination and Seedling Vigor of Magonia pubescens
ABSTRACT The timbó (Magonia pubescens A. St.-Hil.) is a tree species of the family Sapindaceae occurring naturally in the Cerrados of Central Brazil. The objective of this study is to verify the influence of seed size, pre-soaking time in water and seedling production containers in the development of timbó seedlings. The experiment was completely randomize
