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

2. Potassium-modulated physiological performance of mango plants infected by Ceratocystis fimbriata
ABSTRACT Mango wilt, caused by the fungus Ceratocystis fimbriata, is an important disease affecting mango production. In view of the beneficial effects of potassium (K) in other profitable crops and the lack of information about the effect of macronutrients on mango wilt development, the present study aimed to evaluate how mango plants supplied with K respon

3. Oxidative damage and photosynthetic impairment in tropical rice cultivars upon exposure to excess iron
ABSTRACT Iron plays a pivotal role in the redox reactions of photosynthesis and metabolic processes such as chlorophyll synthesis. Iron availability in waterlogged soils can reach toxic levels and promote oxidative stress. Fe toxicity is the most concerning of stresses for rice in many lowland environments around the world and may cause severe impairments in

4. Differential leaf gas exchange performance of mango cultivars infected by different isolates of Ceratocystis fimbriata
ABSTRACT Caused by the vascular fungus Ceratocystis fimbriata, mango wilt is considered to be one of the most serious threats in mango-producing regions worldwide. However, changes in leaf gas exchange level and the mechanisms underlying host responses to this fungal infection remain poorly described. This study aimed to evaluate potential changes in the lea

5. Magnesium-induced alterations in the photosynthetic performance and resistance of rice plants infected with Bipolaris oryzae
Brown spot (BS), caused by the fungus Bipolaris oryzae, is one of the most important diseases contracted by rice. We investigated the effect of magnesium (Mg) on the development of BS, caused by Bipolaris oryzae, and the effects of disease development on the photosynthetic performance of rice (Oryza sativa L.) plants (cv. Metica-1) grown in nutrient solution

6. Photosynthetic gas exchange and antioxidative system in common bean plants infected by Colletotrichum lindemuthianum and supplied with silicon
This study investigated the effects of silicon (Si) on the resistance of common bean plants to anthracnose caused by Colletotrichum lindemuthianum. The plants were grown in a nutrient solution containing 0 (control) or 2 mM Si (+Si) and both photosynthesis and antioxidative metabolism levels were evaluated. The Si concentrations in the leaf tissues of +Si pl

7. Ecophysiological responses to drought and salinity in the cosmopolitan invader Nicotiana glauca
Nicotiana glauca, a shrub native to southern South America, is widely distributed in the Americas, from Patagonia to the USA, from zero up to 3,700 m; it rapidly invades disturbed environments. In Venezuela, it has been reported from zero up to 2,000 m growing in contrasting conditions of relative humidity, temperature, rainfall, and salinity. In order to ga

8. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

10. Preliminary results of a long-term experiment about RDI and PRD irrigation strategies in winegrapes in São Francisco Valley, Brazil.
In the São Francisco Valley, Northeast Brazil, an evaluation of the regulated deficit irrigation (RDI) and partial rootzone drying (PRD) has been performed in winegrape cv. ?Syrah? grafted on rootstocks ?IAC 572? and ?1103 P?. Crop coefficients (Kc) throughout the vineyard establishment and the 1st cycle was estimated. RDI (depletion until 60% of total avai

11. Infrared thermometry to schedule irrigation of common bean.
The objective of this work was to determine the critical irrigation time for common bean (Phaseolus vulgaris L. cv. Carioca) using infrared thermometry. Five treatments were analyzed. Canopy temperature differences between plants and a well-watered control about 1, 2, 3, 4, and 5±0.5ºC were tested. Physiological variables and plant growth were analyzed to

12. Efeito do deficit hidrico no solo sobre o comportamento estomatico e potencial da agua em mudas de seringueira.
O objetivo deste trabalho foi avaliar o efeito do estresse hidrico sobre o potencial da agua na folha da seringueira, a resistencia estomatica, e a recuperacao do potencial de agua na folha. Progenies de polinizacao aberta de seringueira (Hevea spp.), provenientes dos clones IAN 873, RRIM 600, IAN 713 e de pes francos de Hbr, foram cultivadas sob condicoes c
