1. EFFECT OF THE MIST MICRO-SPRAY TIME ON PHOTOSYNTHETIC SPATIAL HETEROGENEITY OF GRAPE CANOPY
ABSTRACT In grape, high temperatures and low humidity prolong midday depression of foliar photosynthesis and dramatically reduce fruit yield. In this study, we explored the effects of various mist micro-spray treatments on grape photosynthesis at a test site in Shanshan County (N, 42.91°; E, 90.30°), Turpan, Xinjiang, China. We tested four different mist m

2. Comparação entre variáveis microclimáticas de local aberto e florestal em um bioma da Mata Atlântica, sul do Brasil
Resumo Na região subtropical do Brasil, o ambiente é naturalmente caracterizado pelo clima quente e úmido. Essas condições são fatores preponderantes para a ocorrência da formação florestal na região, o bioma Mata Atlântica. Associa-se que qualquer condição diferente daquela que não seja natural, pode receber de forma diferenciada a condição

3. Balanço de Energia, Emissão Foliar e Eficiência do Uso da Radiação pela Cana-de-Açúcar em Cultivo sem e com Palhada
Resumo Nas últimas décadas houve mudança no sistema de colheita e manejo da palhada em canaviais de todo o Brasil, visando atender a legislação vigente e reduzir custos. A deposição de resíduos culturais sobre o solo, contudo, modifica as características micrometeorológicas do ambiente. Este trabalho reporta um estudo conduzido em Juazeiro-BA, para

4. Ecological capability evaluation for afforestation and forest expansion using Geographic Information System (GIS) in management area of Caspian Sea
Abstract Ecological capability evaluation is referred to as evaluation of potential capability of land and determination of its natural land use. In this paper, ecological capability of Lille Basin in Lahijan was evaluated for afforestation and forest expansion using Geographical Information Systems (GIS). For this purpose, information layers (slope, elevati

5. Microwave Measurements of Dielectric Properties of Corn Vegetation at C-Band and Comparison with Debye- Cole Dual Dispersion Model
Abstract Microwave irradiations from vegetation canopy are strongly influenced by its dielectric properties and give useful information for microwave remote sensing -interpretation and applications. This paper reports on the laboratory measurements of dielectric properties of corn vegetation at C-Band frequency. Von Hipple method is used to measure complex d

6. Fruit sphere microenvironments and berry phenolic content of Cabernet Sauvignon (Vitis vinifera L.) cultivated under rain-shelter systems with coloured plastic film
Abstract Rain-shelter cultivation has been proven an important cultivation method for grape-plantings in continental monsoon climate zones, of which white plastic films are the most common shelter material. However, while this method and material reduces the occurrence of the disease, it can also decrease the grape berry quality. Five colours (including red,

7. Diurnal Pattern of Leaf, Flower and Fruit Specific Ambient Volatiles above an Oil Palm Plantation in Pará State, Brazil
Oil palm plantations are rapidly expanding in the tropics because of insatiable global demand for fruit oil to be used in food, biofuels and cosmetics. Here we show that three tissue-specific volatiles can be quantified in ambient air above an African-American hybrid oil palm plantation in Brazil and linked photosynthesis (isoprene), floral scent (estragole)

8. Occurrence of homobaric and heterobaric leaves in two forest types of southern Brazil
ABSTRACT In ombrophilous forests, light stratification provokes different adjustments by plants for better use of the environmental conditions of each stratum. Among the morphological traits that vary with strata, the presence of bundle sheath extensions (BSEs) is related to water transport, photosynthesis, and leaf mechanical support and classifies leaves a

9. Edificios en altura másicos y livianos en ciudades-oasis: evaluación térmica y energética de viviendas debajo y sobre la copa de los árboles en Mendoza, Argentina
Abstract From an environmental point of view, the urban forest in Oasis-Cities defines two strata in height: one with a moderate microclimate under the trees, and a second one over the tree canopy that presents an extreme climatic situation. The aim of this study is to assess the energy efficiency and the conditions of habitability of apartments at different

10. Cotton response to mepiquat chloride and temperature
Gibberellin inhibitor growth regulators are used for cotton (Gossypium hirsutum L.) canopy manipulation to avoid excess growth and yield losses. However, under temperatures below or over the optimum for cotton production the effect of mepiquat chloride (MC) has not always been significant. In this experiment, cotton plants were grown in growth chambers to st

11. Influência do efeito de borda sobre a anurofauna do parque estadual Carlos Botelho (SP) / Influence of edge effects in frogs of parque estadual Carlos Botelho (SP)
This study aimed to determine the extent of the edge effect and its influence on the richness and abundance of amphibians in a conservation of the Atlantic Forest in the state of São Paulo, the Carlos Botelho State Park. We used 28 transects with six plots of 4 × 4 m apart and parallel to the edge of this 0, 25, 50, 100, 200 and 300 m, totaling 168 samples

12. Efeitos do uso e cobertura do solo sobre o conforto higrotérmico / Effects of the use and soil cover on the hygrothermal comfort
Given the importance of obtaining an urban design based on the microclimate and the possibility of the use of trees as a factor in mitigation of urban distress, this study evaluated the effect caused by three different spatial arrangements of urban forests and the use and occupation on soil in temperature and humidity of the environment in surroundings area.
