As condições de estresse biótico e abiótico impostas às plantas induzem a superprodução espécies reativas oxigênio (ROS), podendo causar danos estruturas celulares mesmo acarretar morte da planta. respostas bioquímicas fisiológicas superiores ao oxidativo incluem um eficiente sistema defesa antioxidante, que envolve atividade das enzimas superóxido dismutase, catalase, ascorbato peroxidase, peroxirredoxinas, dentre outras, além metabólitos não enzimáticos, que, forma conjunta, atuam na...
Sugarcane (Saccharum officinarum L.) production is influenced by various abiotic stresses, including salt stress.Salinity can induce oxidative stress, which in turn damages biomolecules and cellular structures.However, such damage be avoided or minimized the enzymatic non-enzymatic defense systems of plants.The aim study was to determine effect exogenous proline on Na + K content activity catalase, ascorbate peroxidase two sugarcane genotypes (RB931011 RB872552) grown vitro under stress.The...
The effects of different light quality treatments on in vitro growth and multiplication sugarcane (RB867515) were investigated. plantlets cultivated MS medium containing 1.3 μM 6-benzylaminopurine (BAP), exposed to five treatments: three combinations blue/red LED (70:30, 50:50, 30:70), white-LED fluorescent lamps, during 24 days. Among the treatments, combination 50:50 proportions proved have best results for stem length, fresh mass, leaf number shoot multiplication. Higher content...
La salinidad es uno de los principales factores estrés ambiental, además interferir en el crecimiento las plantas perjudica directamente la producción agrícola. En ese contexto, se destaca importancia investigaciones direccionadas a respuesta sometidas al salino, con fin evaluar comportamiento fisiológico y bioquímico objetivo seleccionar genotipos tolerantes dicha condición. Una técnicas más utilizadas para uniformizar una condición particular cultivo tejidos in vitro. Por lo tanto, este...
ABSTRACT The influence of two aromatic cytokinins (CKs), 6-benzylaminopurine (BAP) and meta-topolin (mT), on in vitro propagation redox metabolism sugarcane (Saccharum spp., variety RB98710) was investigated. Plants were cultured Murashige Skoog (MS) medium supplemented with mT (5 µmol.L-1) or BAP 6.66 for 40 days. use provided an increase the multiplication rate stem length plants shoots when compared to BAP. Shoots generated from treatment presented low malondialdehyde (MDA) content...
The objective of this work was to induce direct somatic embryogenesis from segments immature leaves the RB872552 variety sugarcane and correlate morphogenic event with oxidative stress. Two previously described protocols were utilized for induction in different supplementations culture medium incubation conditions. For conversion embryos into plants used MS without phytoregulators. Histological analyses activity antioxidant enzymes also conducted embryogenic non-embryogenic tissues....
