1. Growth and physiology of maize under water salinity and nitrogen fertilization in two soils
RESUMO A adubação nitrogenada, em geral, minimiza os efeitos da salinidade às plantas, mas a ação mitigadora depende da espécie vegetal, cultivar, textura do solo e idade das plantas, entre outros fatores. Assim, objetivou-se avaliar os efeitos da salinidade da água de irrigação e adubação nitrogenada na fisiologia e crescimento do milho (Zea mays

2. Bacteria in combination with fertilizers promote root and shoot growth of maize in saline-sodic soil
Salinity is the leading abiotic stress hampering maize (Zea maysL.) growth throughout the world, especially in Pakistan. During salinity stress, the endogenous ethylene level in plants increases, which retards proper root growth and consequent shoot growth of the plants. However, certain bacteria contain the enzyme 1-aminocyclopropane-1-carboxylate (ACC) dea

3. Tolerância à salinidade induzida pelo ácido salicílico em sementes e plântulas de milho híbrido / Tolerância à salinidade induzida pelo ácido salicílico em sementes e plântulas de milho híbrido / Salinity tolerance induced by salicylic acid in seeds and hybrid corn seedlings / Salinity tolerance induced by salicylic acid in seeds and hybrid corn seedlings
Diferentes compostos fenólicos são formados no metabolismo secundário dos vegetais, entre eles o ácido salicílico que possui função de defesa atuando como agente antioxidante em situações de estresse. Portanto, o objetivo da realização do trabalho foi avaliar a influência do cloreto de sódio (NaCl) em três lotes de sementes de milho híbrido, b

4. Crescimento, trocas gasosas, partiÃÃo de Ãons e metabolismo do nitrogÃnio em plantas de milho submetidas à salinidade e diferentes fontes de N / Growth, gas exchange, partition of ions and nitrogen metabolism in maize plants subjected to salinity and different nitrogen sources
O objetivo deste trabalho foi estudar o efeito da fonte de N no crescimento, nas trocas gasosas, na partiÃÃo de Ãons e no metabolismo do N em plantas de milho (Zea mays L.) submetidas à salinidade. Para isto, sementes de milho foram semeadas em copos plÃsticos contendo vermiculita, sendo mantidas em casa de vegetaÃÃo. Em seguida, as plÃntulas foram t

5. Efeitos da irrigaÃÃo com esgoto tratado sobre o sistema solo-planta (milho) e induÃÃo da supressividade a doenÃas causadas por nematÃides / Effects of irrigation with treated sewage on soil â plant(maize) system and inducement of suppressiveness to diseases caused by nematodes
The treated effluents have great potential for application in agriculture, due to certain levels of nutrients and organic material that can improvement the chemical characteristics of soils and thus induce suppressiveness of soils to plant diseases caused by phytopathogens. The objective this word was to provide technical subsidies for the fertirrigation of

6. Evaluation of a cycle of the crop rotation of corn-and bean-string, using water of the low and high salinity. / Avaliação de um ciclo de rotação cultural milho e feijão-de-corda, utilizando-se água de baixa e de alta salinidade.
Aiming to assess the effects of salinity in the chemical characteristics of the soil, growth, partition of dry matter and productivity, and the effects of soil salinity on the levels mineral elements contend and the total extracted Na, macronutrients (Ca, K, Mg, P) and micronutrients (Cl, Fe, Cu, Zn and Mn), according to the salinity of the water irrigation,

7. Produção de forragem verde em sistema hidropônico usando esgoto tratado
In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of

8. Alterações químicas no solo, aspectos nutricionais, fisiológicos e de produção da cultura do milho irrigado com água salina / Chemical changes in the soil and nutritional and physiologic, nutritional and productive aspects in maize cropping irrigated with saline water
An experiment was carried out in drainage lysimeters under greenhouse conditions in order to evaluate the effects of the soil solution salinity on the mineral nutrition, growth, development, relative yield and physiologic characteristics as well as the effects of the saline water irrigation upon the chemical properties of an Eutrophic Red Argisol cropped wit

9. Atividade respiratória e metabolismo antioxidativo em raízes de plântulas de milho (Zea mays L.) submetidas ao estresse salino / Respiration activity and antioxidative metabolism in roots of maize (Zea mays L.) seedlings submitted to salt stress
Tolerance to salt stress was studied in maize seedlings (Zea mays L.) cultivars AGN 3150, BR 106, BR 201, BR 206 and SHS 4040, grown in Hoaglands nutrient solution. Treatments with NaCl 50 and 100 mM led to a decrease in the biomass production and to an increase in the relative electrolyte leakage in the roots and shoots in all cultivars. However, the larges

10. Electrotropism of Maize (Zea mays L.) Roots (Facts and Artifacts).
Intact and decapped primary roots of maize (Zea mays L.) were exposed to DC electric fields of 0.5 to 8.0 V/cm in low-salinity media to resolve conflicting results about the direction of electrotropism. In DC fields of 0.5 V/cm or 1.0 V/cm, intact roots always curved toward the cathode. In a field of 8.0 V/cm, intact roots curved toward the anode and stopped

11. Interactive Effects of Salinity and Phosphorus Nutrition of the Concentrations of Phosphate and Phosphate Esters in Mature Photosynthesizing Corn Leaves 1
The effects of salinity on corn plants (Zea mays L.) are influenced by the concentration of nutrient orthophosphate. Salinity (−2 bars each of NaCl and CaCl2) was more injurious in combination with a high concentration of orthophosphate (2 mm) (that gave optimum yields in the absence of salinity) than it was with a lower concentration (0.1 mm). With 2 mm o

12. Salinity Affects Intracellular Calcium in Corn Root Protoplasts 1
Previous work with the fluorescent Ca probe chlorotetracycline (CTC) showed that salinity displaces Ca from membranes of root cells. Using a variety of indirect approaches, we studied whether salinity displaces Ca from the cell surface or from internal membranes of corn (Zea mays L. cv Pioneer 3377) root protoplasts. Preloading the cells with supplemental Ca
