Here we investigate the effect of electromagnetic waves with high radio frequency radiation on the antioxidant enzyme activities and seed germination of Zea mays. Three groups of Zea mays seeds were used in this study. The first group was only exposed to RF radiation emitted from the mobile phone simulator. The second group was only exposed to RF radiation emitted from the mobile phone simulato...

Raffinose family oligosaccharides (RFOs), which include raffinose and stachyose, are thought to be an important source of energy during seed germination. In contrast to their potential for promoting germination, RFOs represent anti-nutritional units for monogastric animals when consumed as a component of feed. The exact role for RFOs during soybean seed development and germination has not been ...

Seed germination is sensitive to glucose (Glc), nitric oxide (NO) and polyamine (PA). To elucidate whether cross-talk among Glc, NO and PAs occurs in mediation of seed germination, effects of Glc, NO and spermine on seed germination of Lotus japonicus were studied. Glc retarded seed germination in a concentration-dependent manner. NO donor sodium nitroprusside (SNP) alleviated Glc-induced inhib...

The present investigation attempted to assess the impact of seed pre-treatments on the germination of Crotalaria persica (Burm. f.) Merr and Tephrosia apollinea (L) Pers. Equally important was our investigation to quantitatively compare different germination parameters used for seed germination studies. The results showed that the final germination was highest for both species under chipping (C...

This paper presents evidence that plant brassinosteroid (BR) hormones play a role in promoting germination. It has long been recognized that seed dormancy and germination are regulated by the plant hormones abscisic acid (ABA) and gibberellin (GA). These two hormones act antagonistically with each other. ABA induces seed dormancy in maturing embryos and inhibits germination of seeds. GA breaks ...

Due to the side effects of chemical drugs, the use of medicinal plants has increased in recent years. In this study, in order to select suitable medicinal plants for planting in the soil of Fars Science and Research Branch of Islamic Azad University, the seed germination characteristics of twenty medical plants were examined. These germination parameters include germination percentage, germinat...

In vitro mass production of C. suaveolens (Lindl.) Hook, an endangered orchid with its snowy white flowers having horticultural potential was accomplished through immature seed culture, and subsequent plant regeneration. The developmental stage of the immature seeds and nutrient media significantly influenced the germination frequency. Seeds at 13 months after pollination cultured on 3% sucrose...

Racemic, (−)-, and (+)-gossypol were evaluated over a concentration range of 0 to 400 μg per mL for effects on several Aspergillus flavus growth parameters. In the concentration range tested, racemic gossypol did not stimulate conidial germination on water agar alone. In a germination stimulatory environment (potato dextrose medium), racemic gossypol concentrations of ≥ 200 μg per mL decreased ...

Aim. To investigate the variability of alpha-amylase isoenzymes in soft wheat varieties Ukrainian selection, created by breeding institutions located different climatic zones (Forest Steppe and Steppe). Methods. Isoenzymes were detected electrophoretic protein separation a polyacrylamide gel. The fall number on «Falling Number 1700» was determined. Results. For representative assessment distrib...

Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling...
