Changes induced by co-inoculation in nitrogen–carbon metabolism in cowpea under salinity stress BJM
Santos,Alexandra de Andrade; Silveira,Joaquim Albenísio Gomes da; Guilherme,Eliezer de Araujo; Bonifacio,Aurenivia; Rodrigues,Artenisa Cerqueira; Figueiredo,Márcia do Vale Barreto.
ABSTRACT To mitigate the deleterious effects of abiotic stress, the use of plant growth-promoting bacteria along with diazotrophic bacteria has been increasing. The objectives of this study were to investigate the key enzymes related to nitrogen and carbon metabolism in the biological nitrogen fixation process and to elucidate the activities of these enzymes by the synergistic interaction between Bradyrhizobium and plant growth-promoting bacteria in the absence and presence of salt stress. Cowpea plants were cultivated under axenic conditions, inoculated with Bradyrhizobium and co-inoculated with Bradyrhizobium sp. and Actinomadura sp., Bradyrhizobium sp. and Bacillus sp., Bradyrhizobium sp. and Paenibacillus graminis, and Bradyrhizobium sp. and...

Plant regulators and invertase activity in sugarcane at the beginning of the harvest season Ciência Rural
Leite,Glauber Henrique Pereira; Alexandre,Carlos; Crusciol,Costa; Siqueira,Gabriela Ferraz de; Silva,Marcelo de Almeida.
Invertases play an essential role in partitioning photosynthates between storage and growth. The objective of this study was to evaluate the activity of acid and neutral invertases and the role they play in controlling the accumulation of sucrose in sugarcane as a result of the application of plant regulators in the beginning of the cropping season.A randomized block experimental design was adopted, with five replicates.The treatments consisted in the application of three plant regulators of the class of growth inhibitors (Sulfomethuron-methyl - 20g ha-1, Glyphosate - 0.4L ha-1, and Compounds from organic carboxylic radicals + Glyphosate - 1L ha-1 + 0.15L ha-1), in addition to a control (natural ripening).The acid and neutral invertase levels are affected...
