As one of two sexual products resulting from double fertilization in angiosperms, the endosperm nourishes its compatriot embryo during seed development and/or germination and ultimately dies. Theoretical studies suggest that the genetic relatedness of an endosperm to its embryo in the same seed might determine the amount of resources ultimately available for the embryo during seed development. ...

REMATURE germinating seeds have been observed in various plants, including P lemons, oranges, melons, wheat and rye. However, in none of these is there any good indication that the premature germination is the result of changes in the germ plasm. Only in maize has the genetic control of this phenomenon been clearly demonstrated. Such mutants have been described by MANGELSDORF (1923,1926, and 19...

Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010/2011 and 2011∖2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield of maize. Maize seeds were treated with Bacillus megaterium (V16), Pseudomonas sp. (StB5, A3, A6, and A61), Burkholderia ambifaria (V9), Entero...

We quantified and characterized the expression of heat-resistant proteins during seed development of maize lines with distinct levels of tolerance to high drying temperature. A corn field was planted for multiplication of seeds of different lines, two tolerant and two non-tolerant to high drying temperatures. Harvest of the seeds was carried out at various stages of development and they were th...

Monospecific polyclonal antibodies against maize leaf phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31) were utilized to examine the subunit composition and developmental profile of endosperm PEPC in developing and germinating castor oil seeds (Ricinus communis L. cv Baker 296). PEPC from developing endosperm consists of a single type of 100-kilodalton subunit, whereas the enzyme from 2- to 5...

ABSTRACT Seed germination events modulate microbial community composition, which ultimately influences seed-to-seedling growth performance. Here, we evaluate the germinated maize (variety SHS 5050) root bacterial of disinfected seed (DS) and non-disinfected (NDS). Using a gnotobiotic system, sodium hypochlorite (1.25%; 30 min)-treated seeds showed reduction population size an apparent increase ...

Reducing maize postharvest storage losses is a challenge for millions of smallholder farmers in Mexico. A previous study documented the effects technologies on stored grain losses. The current follows up those experiments to evaluate effectiveness diverse — polypropylene bags with and/or without insecticide, hermetic metal silos, bags, recycled plastic containers, silage micronized lime, and st...

In these studies, the physical and physiological seed properties seedling's vigour in five ZP maize hybrids (ZP1, ZP2, ZP3, ZP4 ZP5) were investigated. Hybrid was divided into small (SF) large fractions (LF) The hybrid combination size did not significantly (p ≥ 0.05) affect germination. Width, thickness, length, weight, dead seeds, abnormal seedling, stem root growth fresh seedling weight infl...

Effectof exopolysaccharides (EPS) produced by a consortium of cyanobacteria on germination of three crops wheat, maize and rice was studied at different salt concentrations. Production of EPS was found to be stimulated by salts, which in turn had a significant Na+ removal capability from aqueous solution. Seed germination, vigor index and mobilization efficiency in all the three crops remarkabl...

Maize (Zea mays) is one of the most important cereal crops grown principally during raining season in Ethiopia which commonly used for both human consumption and poultry feed. Green house experiment on effect watering frequency germination early growth maize was carried out at Ambo Agricultural Research Center using a hybrid variety (Jibat) from December 1 to January20th, 2018/19. The study con...
