Abstract: The germination of seeds is improved by treating the seeds with a solid-form super absorbent polymer that has absorbed water. Super absorbent polymer particles that contain an amount of water such as about 5 to 7 times their weight that is significantly less than the amount of water they are able to absorb such as about 80-120 times their weight and do not substantially adhere to each other are mixed with seeds to form a mixture that may contain a volume ratio of seeds to polymer particles of 0.2 to 5:1. The mixture is stirred while supplying air or gaseous oxygen into the mixture for a time and at a temperature sufficient to cause the seeds to imbibe sufficient water to enhance their vigor for sprouting, but insufficient to cause sprouting. The mixture is sieved to obtain seeds having essentially no adhering polymer residue of the particles, after which the seeds may be dried. The polymer particles may be spherical, and before absorbing water have a size of 50 to 300 .mu.m.

Abstract: An artificial seed has a powder structure or powder padded layer as a sealing material for anti-contamination purpose. This powder layer, 2-30 mm preferably 5-20 mm in thickness, consists of numerous fine sandy hydrophobic particles. The openings among the particles are small and winding enough to block micro-organisms from penetrating this dry and nutrientless layer into the seed, but not enough to block the needed oxygen. The hydrophobic nature of the particles is also effective to block water permeation and microbes therein, but not effective to block the tissue to grow out of the seed. The powder layer can cover any exposed part of the artificial seed. For the artificial seeds with a water-proof tough shell, the powder layer covers only the mouth or mouths of the shell. But for those with a water-soluble capsule, or water-soluble film, it covers all over the contents of the seeds. In both cases, the powder layer is again covered with the water-soluble film to kept the powder particles in position.

Abstract: Single-gene, non-lethal mutations responsible for low phytic acid-containing seeds are selectable by means of a method for assaying seeds which are otherwise phenotypically, or nearly phenotypically, normal. Maize mutants having from 20% to 95% reductions in kernel phytic acid phosphorus compared to the wild-type, without any noticeable reduction in total phosphorus, were isolated by this method. Mutants obtained in accordance with the invention are useful for developing commercial, low phytic acid seed, plant lines.

Abstract: The invention is drawn to a method of applying a hydrogel coating to embryonic plants to improve early plant growth by controlling the amount of cross-linking. A dry coating of a water-soluble hydrogel in powder form is built up around individual embryonic plants. The powder-coated plants are introduced into a water bath which is free of polyvalent metal ions to partially hydrate the coatings. Rapidly thereafter and before the coatings are fully hydrated, the bath is modified by dispersing cross-linking polyvalent metal ions therein. The contact time of the coated plants in the modified bath is limited so that the polyvalent metal ions diffuse into the coatings and form an inwardly decreasing concentration gradient therein. The plants are separated from the modified bath so that the polyvalent metal ions are redistributed and equilibrated within the coatings. The resulting coatings are in a uniform partially cross-linked condition which promotes leaf emergence and plant vigor.

Abstract: The chemical compounds that induce expression of nodulation genes of Bradyrhizobium japonicum strains have been identified. The isoflavones daidzein and genistein were identified as soybean exudate components that induce nod-genes.

In addition, several flavonoid compounds including 4',7-dihydroxyflavone, apigenin, kaempferol and coumestrol, were also found to act as inducers. Nodulation inducing compositions and a method for selectively activating the expression of a gene under the control of a soybean exudate inducible promoter in B. japonicum in response to these inducer molecules are described. In addition, soybean inoculating compositions containing the nod-gene inducers and inoculating methods employing these compositions are described.

A number of other flavonoids including flavones, flavanones, flavanols and dihydroflavanols, not necessarily found in legume exudates, were also found to induce expression of certain nodulation genes.

Abstract: Coated organisms and particularly coated seeds are provided wherein the coating is comprised of one or more polymeric materials which form a coating having a temperature-dependent permeability with respect to a material such as water permeability. The polymeric materials used in making the coatings are relatively impermeable to the material such as water at cooler temperatures (less than optimum growth or germination temperatures) and relatively permeable at higher temperatures (at or greater than optimum growth or germination temperatures). The variable permeability of the coating prevents imbibition at lower temperatures and allows it at higher temperatures. Accordingly, coated seeds can be planted early in a planting season and undergo imbibition followed by germination under favorable moisture and temperature conditions.
