1. Leaf anatomy of Protium ovatum and its antiproliferative potential in cervical cells
ABSTRACT The aim of this study was to analyze the morphology and anatomy of the leaves of Protium ovatum Engl., Burseraceae, and verify the antiproliferative activity in cervical cells. For anatomical analysis, the leaf samples were fixed in formol, acetic acid, alcohol 70, dehydrated, included in hydroxyethyl methacrylate and sectioned at a thickness of 5�

2. Peculiar anatomical traits, high durability, and potential ornamental use of Cyclanthaceae as fresh foliage
ABSTRACT Wild plant species with potential for use as ornamental green foliage are often reported. Nevertheless, there are few studies evaluating morphological and anatomical aspects associated with this use. Preliminary trials suggest that the species of Sphaeradenia (Sander ex Mast.) Harling, a Cyclantaceae that occurs from Costa Rica to Peru, is suitable

3. Cuticle of 'Gala' and 'Galaxy' apples cultivars under different environmental conditions
This study aimed to analyze the cuticle thickness and pattern of epicuticular wax deposition in 'Gala' and 'Galaxy' apple cultivars (Malus domestica Borkh,) from three Brazilian producing areas: Vacaria (RS), Fraiburgo (SC) and São Joaquim (SC) with altitudes of 971, 1,048 and 1,353m, respectively. Harvested fruit were kept under two storage conditions: reg

4. Aspects of leaf anatomy of Kudzu (Pueraria lobata, Leguminosae-faboideae) related to water and energy balance.
Kudzu is a cover crop that has escaped cultivation in some subtropical and warm temperate regions. Kudzu has previously demonstrated broad intraspecific physiological plasticity while colonizing new environments. The objective of this paper was to investigate characteristics of kudzu leaflet anatomy that might contribute to its successful growth in climatica

5. Leaf plasticity in successive selection cycles of 'Saracura' maize in response to periodic soil flooding.
Abstract ? The objective of this work was to assess the effect of successive selection cycles on leaf plasticity of 'Saracura' maize BRS-4154 under periodical flooding in field conditions. Soil flooding started at the six-leaf stage with the application of a 20-cm depth water layer three times a week. At flowering, samples of leaves were collected and fixed.

6. Aspects of leaf anatomy of tropical kudzu related to water and energy balance.
No Brasil, a pecuaria (Pueraria phaseoloides Benth, Leguminosae-Faboideae) e tradicionalmente empregada como cultura de cobertura em seringais na regiao amazonica, onde as condicoes climaticas se assemelham as condicoes climaticas tropicais encontradas no sudoeste asiatico, centro de dispersao da especie. Pueraria foi tambem introduzida na regiao sudeste do

7. EvoluÃÃo das caracterÃsticas morfoanatÃmicas nos ciclos de seleÃÃo do milho âSaracuraâ sob encharcamento intermitente / Evolution of morpho-anatomicals characteristics on selection cycles of maize (Zea mays L.) âSaracuraâ â BRS â 4154 under intermittent soil flooding
Although every single plant needs a certain amount of water, the excess around roots can cause severe injuries and even death of most crops. Soil flooding is one of the most important factors which affects maize crop production and development on tropical and subtropical regions. Excess of water blocks the oxygen transfer and others gases from soil to atmosp

8. Efeitos da radiação ultravioleta-b sobre a morfisiologia de kappaphycus alvarezii (DOTY) doty ex P. Silva (gigartinales) variantes pigmentares verde e vermelha
The effects of ultraviolet radiation in the biological relevant wavebands of UV-A (315#400 nm) and UV-B (280#315 nm) on algae have become an important issue as a man-made depletion of the protecting ozone layer has been reported. However, experimental designs to investigate this issue are manifold and the target organisms are extremely diverse. Data are incl

9. Defesas foliares em resposta à herbivoria em espécies lenhosas de restinga,Ipojuca-PE
The leaf, the major photosynthetic plant organ, has the important function to adjust the plants to different habitats through morphological, chemical and physiological changes as a defense against the environmental factors. The chewing insects, the major consumers of leaf tissues, prejudice the behavior of the plants through the consumption of the photosynth

10. Foliar anatomy of species of Chamaecrista Moench. (Leguminosae/Caesalpinioideae) occurring in rupestrial fields / Anatomia foliar de espécies de Chamaecrista Moench. (Leguminosae/Caesalpinioideae) ocorrentes em campo rupestre
Minas Gerais state flora presents different biomas but little is known about the diversity of its species, some of which secrete natural compounds having well-known biological activity. There is a large number of species of recognized economic interest in the Leguminosae family and in the rupestrial fields of Minas Gerais, totaling 28 of the 351 species incl

11. Submergence-Induced Morphological, Anatomical, and Biochemical Responses in a Terrestrial Species Affect Gas Diffusion Resistance and Photosynthetic Performance
Gas exchange between the plant and the environment is severely hampered when plants are submerged, leading to oxygen and energy deficits. A straightforward way to reduce these shortages of oxygen and carbohydrates would be continued photosynthesis under water, but this possibility has received only little attention. Here, we combine several techniques to inv

12. Chemical Composition of the Prunus laurocerasus Leaf Surface. Dynamic Changes of the Epicuticular Wax Film during Leaf Development1
The seasonal development of adaxial Prunus laurocerasus leaf surfaces was studied using newly developed methods for the mechanical removal of epicuticular waxes. During epidermal cell expansion, more than 50 μg leaf−1 of alkyl acetates accumulated within 10 d, forming an epicuticular wax film approximately 30 nm thick. Then, alcohols dominated for 18 d of
