Superoxide generated during the early imbibition is an excellent marker for evaluating seed vigor. In this paper, a new principle biosensor for non-invasive detection of seed vigor based on quantitative measurement of superoxide via selective probe 2-methyl-6-(p-methoxyphenyl)-3,7-dihydroimidazo [1,2alpha] pyrazin-3-one (MCLA)-mediated chemiluminescence (CL) was developed. The biosensor, which ...

The success of germination, growth and final yield of every crop depends to a large extent on the quality of the seeds used to grow the crop. Seed quality is defined as the viability and vigor attribute of a seed that enables the emergence and establishment of normal seedlings under a wide range of environments. We attempt to dissect the mechanisms involved in the acquisition of seed quality, t...

Abstract: The association between beneficial microorganisms and green beans can accelerate establishment in the field. objective of this study was to investigate influence seed treatments different doses Bacillus subtilis on physiological potential beans. Seeds from cultivar Macarrão Baixo were used. used a completely randomized design double factorial scheme with factor A treatments: Pellicula...

An experiment was carried out at the Department of Field Crops laboratory, College Agriculture, University Tikrit, in order to know effect stimulating stored seeds triticale Farah cultivar by α -amylase enzyme using a complete random design (CRD) factorial experiment. The first factor storage periods 6 months, 1.5 years and 2.5 (S1,S2 S3) second concentrations 0 (dry seeds), soaked distilled wa...

PURPOSE to evaluate the effect of delivery type and usual obstetric procedures on the neurologic condition of a sample of consecutive term and healthy neonates, in the first 48 hours of life, using the Neurologic Adaptative Capacity Score (NACS) system. METHODS cohort prospective study with 313 neonates, from a neonatology unit: Unidade de Neonatologia e Alojamento Conjunto. The variables ana...

J. Am. Soc. Brew. Chem. 68(3):125-131, 2010 Genetic information for male and female hop accessions is limited, hampering parental selection to maximize offspring productivity. Our objective was to determine whether amplified fragment length polymorphism (AFLP)derived genetic distance (GDmm) estimates and coancestry estimates from pedigrees (GSped) between parental pairs could be used to predict...
