The cold tolerance studies were carried out in a bi-parental F2 population of cross between tolerant and susceptible parents (SKUA-529 HEERA, respectively). purpose was to screen the individuals for primary cold-tolerance-related attributes. information generated has direct application use identifying quantitative trait loci (QTLs) further can be used genotyping with an appropriate marker syste...

This research is an experimental study that aims to determine the effect of application N2-fixing bacteria Actinomycetes, Azospirillum, and Azotobacter on vegetative growth parameters corn plants nitrogen content plants. Parameters for measuring include: formation rate radicle length, plant height, number leaves, leaf fresh weight plants, roots, dry total N in as well physical chemical qualitie...

BACKGROUND AND AIMS The small leafy succulent shrub Halocnemum strobilaceum occurs in saline habitats from northern Africa and Mediterranean Europe to western Asia, and it is a dominant species in salt deserts such as those of north-west China. The effects of temperature, light/darkness and NaCl salinity were tested on seed germination, and the effects of salinity were tested on seed germinatio...

BACKGROUND AND AIMS The root meristem of the Arabidopsis thaliana mature embryo is a highly organized structure in which individual cell shape and size must be regulated in co-ordination with the surrounding cells. The objective of this study was to determine the role of the AUX1 LAX family of auxin import carriers during the establishment of the embryonic root cell pattern. METHODS The radic...

Histone acetylation is known to affect the speed of seed germination, but the molecular regulatory basis of this remains ambiguous. Here we report that loss of function of two histone deacetylase-binding factors, SWI-INDEPENDENT3 (SIN3)-LIKE1 (SNL1) and SNL2, results in accelerated radicle protrusion and growth during seed germination. AUXIN RESISTANT 1 (AUX1) is identified as a key factor in t...

Class I chitinase (Chi9) and beta-1,3-glucanase (GluB) genes are expressed in the micropylar endosperm cap of tomato (Lycopersicon esculentum) seeds just before radicle emergence through this tissue to complete germination. In gibberellin (GA)-deficient mutant (gib-1) seeds, expression of Chi9 and GluB mRNA and protein is dependent upon GA. However, as expression occurs relatively late in the g...

in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

Six varieties of durum wheat were included in a full diallel mating design during 2003-2004 and 2004-2005 cropping seasons in the farm of Maragheh Dryland Agricultural Research Institute (DARI), Iran. Parental durum wheat genotypes and their complete diallel progenies were grown in a randomized complete block design with two replications in the growing seasons of 2005-06. The highest values of ...

Abstract Background Seed germination is the most important stage for formation of a new plant. This process starts when dry seed begins to absorb water and ends radicle protrudes. The rate from different species varies. rapid that grow on marginal land allows seedlings compete with surrounding species, which also guarantee normal plant development high yield. Pearl millet an cereal crop used wo...
