Cultivation of water lettuce with different doses of salinity. With the increase in pollution of water bodies, there is a need to look for decontamination alternatives. Thus, there is a need for more studies aimed at removing these pollutants, with phytoremediati... ... Repository: BDPA Publication year: 2023
Silicon in the anatomy and physiology of banana plant leaves under temporary immersion bioreactors. Banana is a crop with outstanding economic and social expression throughout the world, therefore, it is important to use appropriate methods of propagation. The micropropagation is an appropriate meth... ... Repository: BDPA Publication year: 2021
Nitrate reductase activity and spad readings in leaf tissues of guinea grass submitted to nitrogen and potassium rates. Nitrogen and K deficiency are among the most yield limiting factors in Brazilian pastures. The lack of these nutrients can hamper the chlorophyll biosynthesis and N content in plant tissues. A greenho... ... Repository: BDPA Publication year: 2010
Gas exchange in massai grass under five nitrogen fertilization levels during establishment and regrowth. The objective of this study was to evaluate gas exchange in the massai grass during establishment and regrowth cycles in a greenhouse, using five nitrogen (N) fertilization levels. A completely random... ... Repository: BDPA Publication year: 2011
The interaction of high copper and zinc doses in acid soil changes the physiological state and development of the root system in young grapevines (Vitis vinifera). Old vineyards may present high copper (Cu) content in the soil due to the frequent application of Bordeaux fungicide to control leaf fungal diseases. Thus, many wine makers replace copper fungicides b... ... Repository: BDPA Publication year: 2018
Use of uniconazole in growth regulation and biochemical changes in maize. ABSTRACT - The current paper evaluated the incubation time, and doses of Uniconazole (UCZ) applied to maize seeds to verify the plants? response at different phenological stages. MSG1001 hybrid seeds... ... Repository: BDPA Publication year: 2022
Impacts of saline stress on the physiology of Saccharum complex genotypes. Knowledge of the physiological mechanisms in saline environment may boost sugarcane breeding programmes targeting abiotic stresses. Our hypothesis is that the physiology of Saccharum genotypes respond... ... Repository: BDPA Publication year: 2022
Gas exchange in Massai grass fertilized with nitrogen and grazed by sheep. The knowledge of gas exchanges in forage plants is essential for a better understanding of the process of forage biomass production in pasture. This study evaluated the gas exchange in massai grass fe... ... Repository: BDPA Publication year: 2020
