1. Gas exchange and water stress index in soybean cultivated under water deficit and soil compaction
ABSTRACT Water stress is intrinsically related to soil water availability which is determinant in gas exchanges, as well as soil compaction in soybean growth and development. This study aimed to evaluate the leaf gas exchange, water stress index, and dry mass accumulation of soybean cultivated in different daily irrigation depths and bulk density. The treatm

2. Does an urban environment affect leaf structure of Eugenia uniflora L. (Myrtaceae)?
ABSTRACT External factors can interfere with the structure and biological activity of plants. Nevertheless, the susceptibility of plants to specific environmental conditions varies, which raises many questions about the behavior of medicinal plants when grown in urban areas. This study aims to detect possible changes induced by exposure of Eugenia uniflora L

3. 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

4. Physiological differences of ‘Crocantela’ lettuce cultivated in conventional and hydroponic systems
RESUMO As plantas cultivadas em sistemas a campo e em hidroponia apresentam grandes diferenças em relação a disponibilidade hídrica e nutricional, afetando o ciclo de desenvolvimento e metabólico, a anatomia dos órgãos e o desempenho das plantas devido a mudanças no comportamento fisiológico e bioquímico. O objetivo deste trabalho foi avaliar o des

5. IN VITRO DEVELOPMENT OF YELLOW LAPACHO (BIGNONIACEAE) USING HIGH-POWER LIGHT EMITTING DIODE
RESUMO Handroanthus ochraceus (ipê-do-cerrado) é uma árvore medicinal, ornamentais e um recurso de madeira que pode ser propagada por cultura in vitro. Os métodos convencionais de propagaçao usam iluminação fluorescente (FL) e recentemente os diodos emissores de luz (LEDs). Este trabalho avalia os efeitos do FL e do LED de alta potência (HP-LED) na p

6. Ecophysiological leaf traits of native and exotic palm tree species under semi-arid conditions
ABSTRACT The main goal of this study was to evaluate the performance of two palm species under semi-arid conditions during the rainy and dry periods: the semi-arid native Syagrus coronata and a native to tropical America, Acrocomia aculeata. The leaf water potential, gas exchange, leaf soluble sugars, starch, free amino acids, total soluble protein content a

7. Morphological Plasticity and Gas Exchange of Ligustrum lucidumW.T. Aiton in Distinct Light Conditions
ABSTRACT The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological param

8. Ploidy levels in Citrus clementine affects leaf morphology, stomatal density and water content
The objective of the present study was to understand the relationship among leaf morphology, stomatal characteristics and water relations in triploids generated through anther culture and their counterpart diploid plant of C. clementina. Triploid plants possessed small and narrow leaves as compared to diploid plant as evident by less leaf length, leaf width

9. The bioindicative potential evaluation of Tabebuia alba (Cham.) Sandwith, Bignoniaceae, in urban atmospheric pollution
This study aimed to evaluate the existence of leaf anatomic characteristics in Tabebuia alba changed by air pollutants, which could be used as tool for a bioindication program. The quantification of mutagenic events on pollen grains also were measured. For this, median leaves and pre-anthesis flowers were collected from the adult plants from three places of

10. Ecophysiology of deciduous plants grown at different densities in the semiarid region of Brazil
Physiological differences in the Cordia oncocalyx tree growing at different densities in two distinct areas were investigated. An agrosilvopastoral system (AGP) and a secondary forest (SF) were studied. Under both types of land-use, C. oncocalyx presented a relative frequency of approximately 50%, and absolute densities of 670 and 80 individuals per hectare,
