Does Illumination of Non-Mature Cereal Kernels During Drying Affect the Germination Ability?

Abstract

The principle of the market competitiveness of breeding companies implicates a fast production of new varieties. One way to achieve this goal brings single seed descent (SSD) methodology, which requires kernels collection (18-23 days after pollination) , fast drying amd germination. Seed drying conditions influence the germination. In present work the influence of lightings: Sanyo LED and incandescent lamp vs. dark control during drying were studied. Kernels were harvested 18 and 23 days after pollination of wheat, triticale and barley cultivars grown in the same field experiment in 2015. It was found that: • the germination ability of non-mature kernels depends on all studied factors: lighting during drying, terms of harvesting and the interaction light * term; • non mature kernelsare more sensitive to drying conditions; • lighting during seeds drying can have a positive effect on ability to germination; • for breeding practice it would be better to harvest kernels at 23 DAF and dry them at room conditions under incandescent lamp.

Influence of the Static Magnetic Field and Algal Extract on the Germination of Soybean Seeds

“…Many authors present hypotheses regarding changes caused by physical phenomena induced by MF, for example changes in liquid crystal properties (cell membranes exhibit many properties of liquid crystal structures), as well as Hall, Dorfman and Ettinghausen effects [19][20][21][22][23][24]. Furthermore, water treated with the MF changes its physicochemical properties, and this may influence the course of some biochemical reactions [25][26][27][28][29][30][31]. Even such a very simplified summary of hypothetical explanations of the magnetic biostimulation mechanisms of plant cells shows how complex this phenomenon is.…”

Influence of the Magnetic Field on the Germination Process of Tosca Bean Seeds (Phaseolus Vulgaris L.)

“…Many hypotheses concern the changes caused by physical phenomena induced by a magnetic field, for instance changes in the properties of liquid crystals (cell membranes exhibit many properties of liquid crystal structures), as well as the Hall, Dorfman, and Ettinghausen effects (Polk and Fellow, 1991;Rosen, 2010;Podleśny and Pietruszewski, 2007;Blanchard, 1996;Aceto et al, 1970). Moreover, water treated with a magnetic field changes its physicochemical properties, which can influence the course of some biochemical reactions (Reina et al, 2001;Es'kov and Darkov, 2003;Moussa, 2011;Grewal and Maheshwari, 2011;Małuszyńska et al 2016). Even such a simplified summary o f hypothetical explanations of underlying mechanisms induced by magnetic biostimulation of plant cells indicates what a complex phenomenon it is.…”
