During this period germination and establishment of alginate-coated seeds were still high (80-85% and 45-60%, respectively). It is considered that the germination lag of the alginate-coated seeds could be influenced by the initial water content of the alginate coating. Rheological measurements are a suitable method for showing the mechanical effects of the structural differences in alginate molecules. Half the seeds were placed in storage in this condition and the other half were coated with alginate gel prior to storage. In total, 30% of naked seeds were removed from storage because of fungal contamination, whereas only 16% of alginate-coated seeds had to be removed. However, in the present study, the time for germination to occur in storage was less in the alginate-coated than the noncoated seeds. Visible contamination of the naked seeds was first noted after 6 days of storage, but after 38 days of storage in alginate-coated seeds. Naked seeds and seeds coated with an alginate gel were stored under conditions designed to prevent water loss and viability was measured periodically. Encapsulating seeds from which the pericarp had been removed (naked seeds) in an alginate gel increased storage lifespan fourfold compared with naked seeds. However, the number of seeds visibly contaminated with fungi and the rapidity with which this contamination became apparent were much reduced in alginate-coated seeds. Contamination of naked seeds occurred earlier and was more extensive than in alginate-coated seeds. The germinability of alginate-coated seeds declined slightly after 25 days storage, but remained high until the end of the experiment. Both strains tended to form dynamic network structures that were induced by entanglements of the alginate molecules. This factsheet [1] summarizes the characteristics of alginate dressings, their indications and contraindications, how to use them and nursing considerations. Animals of the control group received a similar amount of sodium alginate pellets prepared without fungus and mixed in the same quantity of supplement feed. This process resembles the dissolution of alginate gels by chelating agents, but the chemical nature of the polymers involved in this biofilm has not been investigated. When the coating was firm enough, the seeds were placed between layers of paper towel and left overnight so that excess water dried from the alginate. Evidently, acetylated alginate seems to be mainly responsible for cohesion of the biofilms by forming a three-dimensional polymer network of relatively high elasticity in which the cells are embedded. |
