چکیده

O efeito do peróxido de hidrogênio vem sendo muito estudado, mas pouco se sabe sobre o seu na germinação e crescimento inicial sementes meloeiro submetidas ao estresse salino. Neste contexto, objetivou-se avaliar como atenuante salino das meloeiro. trabalho foi realizado no Laboratório Sementes Mudas da Universidade Federal Campina Grande, campus Pombal-PB. experimento conduzido em delineamento inteiramente casualizado, esquema fatorial 4 x 6, tempos embebição H 2 (TE 1 : 0; TE 8; 3 16 4: 24 horas) níveis salinidade água irrigação (0,3; 1,2; 2,1; 3,0; 3,9 4,8 dS m -1 ), com quatro repetições. Foram utilizadas variedade comercial Imperial-45. A solução preparada a partir uma 1mmol L , diluída para atingir concentração 10 µmol posteriormente foram acondicionadas becker embebidas 100 ml por diferentes . As variáveis ​​avaliadas foram: porcentagem germinação, primeira contagem índice velocidade média tempo médio comprimento radícula. O2 horas atenuam os efeitos causados ​​pelo até 2,2 porém quando causaram prejuízos processo germinativo

Activation of Germination in Douglas Fir Seed by Hydrogen Peroxide.

The stimulation of the photooxidase by ammonium sulfate and potassium phosphate was examined in some detail. Maximum stimulation was as much as 10-fold in 1.3 to 1.5 M (NH4)9SO4 in the presence of 0.3 mM KCN. Part of this stimulatory effect was due to the cyanide. Phosphate and citrate also stimulated strongly, and salts of monovalent anions had smaller effects. Many typical inhibitors of photo...

Different Modes of Hydrogen Peroxide Action During Seed Germination

Hydrogen peroxide was initially recognized as a toxic molecule that causes damage at different levels of cell organization and thus losses in cell viability. From the 1990s, the role of hydrogen peroxide as a signaling molecule in plants has also been discussed. The beneficial role of H2O2 as a central hub integrating signaling network in response to biotic and abiotic stress and during develop...

Physiological and phytochemical changes induced by seed pretreatment with hydrogen peroxide in Artemisia sieberi under salt stress.

Seeds of medicinal plant Artemisia sieberi were pretreated with H2O2 (0, 10, 50, 90, and 140 µM) and grown in saline condition (0 and 150 mM NaCl) for one month. Phytochemical properties such as antioxidant capacity and also salt tolerance in the plans arising from H2O2 pretreated seeds under salt stress were examined. Results showed a decrease in H2O2 and malondialdehyde concentrations in the ...

Cryptic Genetic Variation for Arabidopsis thaliana Seed Germination Speed in a Novel Salt Stress Environment

The expansion of species ranges frequently necessitates responses to novel environments. In plants, the ability of seeds to disperse to marginal areas relies in part to its ability to germinate under stressful conditions. Here we examine the genetic architecture of Arabidopsis thaliana germination speed under a novel, saline environment, using an Extreme QTL (X-QTL) mapping platform we previous...

Identification of novel loci for salt stress at the seed germination stage in soybean

Salt tolerance in soybean [Glycine max (L.) Merr.] at the seed germination stage is a critical determinant of stable stand establishment in saline soil. This study examined one population of 184 recombinant inbred lines (RILs, F7:11) derived from a cross between Kefeng1 and Nannong1138-2 and one natural population consisting of 196 soybean landraces. A total of 11 quantitative trait loci (QTLs)...
