Understanding germination requirements of native species is an important component of restoration in south Puget Lowland prairies (Washington, USA). We conducted an experiment to determine the effects of pre-germination treatment and germination temperature conditions on the proportional germination of three species of Lupinus. For one species, Lupinus lepidus, germination was highest following...

infection process including spore germination, penetration and intercellular development of cercospora beticola in the mesophyll of immature and mature leaves of two resistant  (fd0018 and hm1836) and a susceptible genotypes (236) of sugar beet were studied, in order to determine the relative importance of defense phenomena in pre and post-penetration stage of infection to the pathogen in sugar...

Smirnovia iranica (Sabeti) synonym: Smirnovia turkestana (Bunge) is a deciduous perennial bushy species of the Fabaceae (Papilionaceae) family. The species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. They have an important role in natural vegetation of desert and sand dune stabilization. Limited growing areas, grazing due to good pa...

BACKGROUND Thioredoxin h (trx h) is closely related to germination of cereal seeds. The cDNA sequences of the thioredoxin s (trx s) gene from Phalaris coerulescens and the thioredoxin h (trx h) gene from wheat are highly homologous, and their expression products have similar biological functions. Transgenic wheat had been formed after the antisense trx s was transferred into wheat, and it had b...

The scarcity of surface water has led to the use underground sources as an alternative for crop irrigation by farmers in semi-arid regions. However, these generally have high salinity, which prevents agricultural production. objective this study was determine effects pre-germination treatments with plant growth regulators and bioactivators on melon seeds attenuate salt stress caused during germ...

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...

In this study, the effects of pre-germination at different doses acetyl salicylic acid (ASA) solution on germination and emergence performance “Nantes” carrot cultivar (Daucus corata L.) seeds under salt stress were investigated in laboratory conditions. Seeds pre-germinated a climate cabinet for 24 hours 0, 50, 100 150 mg L-1 ASA solutions hydropiriming 15oC. After process, they divided into t...
