1. Millet irrigation with treated wastewater: Gas exchange response and nutrient accumulation
RESUMO As águas residuárias podem ser consideradas como uma fonte hídrica e nutricional excelente para as plantas cultivadas. Porém, a presença de altas concentrações de sais e de compostos tóxicos pode afetar negativamente as plantações. Avaliou-se o efeito da irrigação com diferentes concentrações de água residuária tratada sobre o acumulo

2. Foliar application of silicon decreases wheat blast symptoms without impairing photosynthesis
ABSTRACT Considering the importance of blast, caused by Pyricularia oryzae, to impact wheat yield, this study investigated whether the foliar spray of potassium silicate (PS) could affect the photosynthesis of wheat plants and its potential to reduce disease symptoms. The Exp. 1 aimed to determine the effect of the foliar spray of PS on the photosynthetic pe

3. Does Spraying of Atrazine on Triazine-Resistant Canola Hybrid Impair Photosynthetic Processes?
RESUMO: A canola é uma importante cultura para rotação na estação fria, e o uso de híbridos com resistência à atrazina pode contribuir para o aumento da produtividade. Este trabalho objetivou avaliar o efeito da atrazina nos processos fotoquímicos e bioquímicos da fotossíntese em canola resistente a triazinas. O experimento foi conduzido em casa d

4. Mitigation of drought stress effects on soybean gas exchanges induced by Azospirillum brasilense and plant regulators
RESUMO O déficit hídrico é limitante à produção agrícola, tendo como efeito primário a redução nas trocas gasosas vegetais, e a continuidade da incidência resulta em menor produtividade. Objetivou-se avaliar as respostas fotossintéticas e a produção de soja sob déficit hídrico severo induzido, em relação à inoculação via semente e aplica

5. Photosynthesis and Growth of Copaiba Seedlings Subjected to Soil Flooding
ABSTRACT The present study aimed to evaluate the effects of soil flooding on photosynthesis, growth, and biomass partitioning of young plants of copaiba (Copaifera lucens Dwyer, Fabaceae ) to investigate the possibility of using this species in restoration projects of riparian forests. Based on our results, we concluded that young plants of C. lucens are ab

6. Research on Phosphorus Removal in Artificial Wetlands by Plants and Their Photosynthesis
ABSTRACT Urban rainfall runoff pollution has become a major reason for water eutrophication problem in the process of urbanization in China, while phosphorus is a significant restrictive factor that influences primary productivity of freshwater system. It's rather significant to conduct phosphorus control in waste water with engineering measures. This resear

7. Freeze tolerance differs between two ecotypes of Paspalum vaginatum (Poaceae)
Morphological and physiological responses to freezing were evaluated in two ecotypes of the perennial turfgrass Paspalum vaginatum. Leaf extension rate, number of active meristems, leaf water potential and net photosynthesis were measured on plants of both a commercial cultivar, 'Sea Isle 2000', and a wild ecotype from the Flooding Pampa grasslands of Argent

8. 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

9. The chlorophyll a fluorescence as an indicator of the temperature stress in the leaves of Prunus persica
Plants growing in temperate regions are often exposed to stress conditions caused by high temperatures. Photosynthesis is one of the metabolic processes most sensitive to high temperature stress, and it is often inhibited before other cellular functions. Using peach leaf disks, we studied the transient chlorophyll a fluorescence along with the gas exchanges

10. 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

11. 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

12. Glomus intraradices improved salt tolerance in Prosopis alba seedlings by improving water use efficiency and shoot water content
The present work was aimed at testing the hypothesis that mycorrhizal Prosopis alba, an economically important tree species worldwide, presents increased salt-tolerance compared with non-mycorrhizal ones and at gaining insight into the possible mechanisms underlying that improvement. For this purpose, a randomized complete block experiment with two factors:
