Roots get their moisture and oxygen near the surface, and eventually those roots will extend well past the drip line.
If the seed has warmth, moisture and oxygen, the change in the phytochrome breaks the seed's dormancy and allows germination.
3M embeds quantum dots from Nanosys in sheets of plastic coated with a film that protects against moisture and oxygen.
Barrier properties of packaging materials against moisture and oxygen penetration are of high relevance.
Often mixed with a mineral named perlite, it is highly valued by horticulturists for its ability to retain moisture and oxygen without becoming waterlogged or heavy.
Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.
All measurements were performed in vacuum (~10−4 torr) to prevent unwanted effects due to moisture and oxygen from the ambient environment35,36,37.
Shelf-life of many foods is largely dependent on the barrier to moisture and oxygen of the respective package.
In theory, a carefully constructed and maintained heap, with just the right proportions of ingredients, moisture and oxygen, can reach and hold temperatures high enough to kill most bacteria, fungi and weed seeds.
Moreover, PSCs are sensitive to high temperatures, UV-light, moisture and oxygen: factors that are hindering their commercialization.
Noninfectious plant diseases are caused by unfavourable growing conditions, including extremes of temperature, disadvantageous relationships between moisture and oxygen, toxic substances in the soil or atmosphere, and an excess or deficiency of an essential mineral.
