Future Forests will benefit from container design that focus on root development and control during formative growth in the nursery. After seed germination advancing roots are carefully guided to side openings in the walls of each cell in which the seedling is being raised. Upon arrival root tips and bottom leader roots are air pruned. Once planted the seedlings roots will quickly seek moisture and nutrients in surrounding soils and anchor the seedling supporting its early and advanced growth and the branching canopy. No root curl to slow plantation growth and reduced risk of toppling. Our range of seedling growing trays is endorsed by foresters in Finland Sweden, Australia, and New Zealand.
These trays are coated with silver nano of 99.9% purity. The silver coating on the tray is designed to increase the amount of light, via reflection, that reaches the backside of the leaf thus maximising the photosynthesis within a short period of time from germination to the unfolding of the foliage leaf. The surface temperature on the silver tray is 5-7 degrees lower than with black trays and therefore this will reduce stress on the surrounding root. By lowering the air humidity that surrounds the plant, it should also decrease the possibility of diseases. Silver trays will inhibit pests such as aphids, mites, moths and flies from resting on the back of leaves during the initial stage of rearing of the seedling as well as preventing the formation of bacteria propagated by fungal spores and bacterial strains.
The presence of a copper coating on the plug tray results in the inhibition of cell division at the root apex and produces an inhibitory effect on root elongation at the root/container wall interface. This creates an abundance of higher order laterals and their growth is, in turn, stopped at the container wall, resulting in a root system with many branched roots within the plug. Once these seedlings are transplanted, root tips resume growth, producing a more branched root system, with more roots in the top section, better able to exploit water and nutrient resources and with better seedling stability (Ruehle, 1985; Smith and McCubbin, 1992; Struve et al., 1994).
