1. Respostas fisiológicas de genótipos de fava (Phaseolus lunatus L.) submetidas ao estresse hídrico cultivadas no Estado do Ceará
Resumo Das espécies do gênero Phaseolus, a fava é a mais tolerante à seca se comparada com os feijões comuns. Apesar da sua importância, ela tem sido pouco estudada, necessitando de pesquisas aplicadas à cultura para maior compreensão dos mecanismos envolvidos na resposta ao déficit hídrico. Este estudo avalia a tolerância de quatro genótipos de

3. Morpho-physiological characteristics by sweet potato cultivars as function of irrigation depth
Abstract The sweet potato is an alternative energy source, but its sustainability depends on efficient water use. The objective of this study was to evaluate sweet potato morpho-physiological characteristics, and water use efficiency (WUE). Irrigation depths of 50, 75, 100, and 125% of crop evapotranspiration (ETc) were applied. The morpho-physiological indi

4. 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

5. Physiological limitations in two sugarcane varieties under water suppression and after recovering
Increasing water scarcity and depleted water productivity in irrigated soils are inducing farmers to adopt improved varieties, such as those with high-capacity tolerance. The use of tolerant varieties of sugarcane might substantially avoid the decline of productivity under water deficit. This research aimed to evaluate the harmful effects of drought on the p

6. Uma abordagem neurofisiológica da acetilcolina em plantas de milho hidratadas e sob condições de estresse hídrico / A neurophysiological approach to acetylcholine in maize plants hydrated and under water stress conditions
The occurrence of action potential and neurotransmitters, the major components of animal nervous system, in plants, bacteria and fungi, shows the universality of signaling principles and information transmission in the way of chemical and electrical signals in all organisms. These study topics, along with plant intelligence and vesicular-based auxin transpor

8. Photosynthesis and antioxidant activity in Jatropha curcas L. under salt stress
Biodiesel is an alternative to petroleum diesel fuel. It is a renewable, biodegradable, and nontoxic biofuel. Interest in the production of biodiesel from Jatropha curcas L. seeds has increased in recent years, but the ability of J. curcas to grow in salt-prone areas, such as the Caatinga semiarid region, has received considerably meager attention. The aim o

10. Respuesta del duraznero a diferentes patrones de aplicación del agua
An experiment was carried out for three years (2004/05 to 2006/07) on a just implanted peach grove, in the south of Uruguay. Five irrigation treatments were applied: without irrigation (T1), drippers of 1.6 L h-1 at 0.4 m (T2), drippers of 4 L h-1 at 1 m (T3), microjets of 21 L h-1 at 5 m (T4) and drippers of 2 L h-1 at 1 m, two lines by row (T5), following

12. Fotossíntese, osmorregulação e crescimento inicial de quatro variedades de cana-de-açúcar submetidas à deficiência hídrica. / Photosynthesis, osmorregulation and initial growth of four sugarcane varieties submitted to water deficiency.
The water deficiency of soil is a problem that affects good part of the areas cultivated in the world, over all, to those situated ones in the half-barren regions. The sugarcane is a culture in expansion in the Northeast of Brazil, where the limitation in the water availability for the plant affects the growth and the development of the plant, causing, exces
