However, if ROS accumulate to harmful levels, seeds lose their ability to control ROS and cannot restart their metabolism [ 37], probably because ROS cause irreversible oxidative damage to lipids, proteins, and DNA.
Cryopreservation without vitrification was not harmful to seed recovery, with no significant difference in germination between the non-cryopreserved and cryopreserved treatments without PVS2 (χ1 = 0.34, P = 0.55), (Fig. 4b).
With organic, you're keeping harmful chemicals and GMO seeds out of the earth's precious soil.
As oxygen demand increases under low water potentials (Verslues et al. 1998), the reduced oxygen availability would be additionally harmful to the germinating seeds.
Postcopulatory sexual selection has been argued to be an important evolutionary force [ 10, 11] and to shape for example the evolution of "giant sperm" in Drosophila hydei that are 10 times the adult body length [ 12], or harmful male genitalia in seed beetles [ 13].
These could include weed seeds, feces, and harmful bacteria and fungi from diseased plants.
It is argued by some that the commercial use and release of genetically modified seeds could be harmful to both other plants and human health.
Is ingesting semen harmful?
Assisted migration was controversial, however, because animal relocation and plant seeding could introduce harmful organisms to ecosystems that had little or no way of coping with them, risking further loss of biodiversity.
M. oleifera (MO) seed, which is not harmful to human and does not have significant drawbacks, has been applied for wastewater treatment (Bina et al. 2010; Alo et al. 2012; Eman et al. 2014).
