20090126268 | Multifold Oxygen Measurement Device - The invention relates to a plant cultivating environment comprising: an oxygen sensing arrangement for sensing an oxygen level in said environment. According to the invention, said oxygen sensing arrangement comprises a base plate for underlying a substrate; and a plurality of oxygen sensors each positioned on said base plate at a predetermined position for sensing a local oxygen level in said substrate. In this way, a water irrigation strategy can be based on sensed levels at a plurality of positions. | 05-21-2009 |
20100186297 | OXYGEN-CONTROLLED PRIMING OF SEED - The present invention relates the methods, compositions and devices for priming of plant seed, preferably seed of crop plants, and seeds obtained with said methods, compositions and devices, wherein the metabolic activity necessary for germination of the seed is not controlled by water but rather by the partial oxygen pressure and/or partial carbon dioxide pressure. In the methods of the invention the partial oxygen or carbon dioxide pressure may be measured by means of an oxygen/carbon dioxide sensitive fluorescent dye. The invention further relates to processes for producing a primed seed lot of a plant species and to a container comprising primed seed under an atmosphere with a partial oxygen pressure that is below the critical oxygen pressure. | 07-29-2010 |
