Conteúdo: |
Fungi in the Aspergillus and Penicillium species are a major cause of decay, and loss of germinability of seeds stored at relative humidities greater than 75%. Uptake of moisture was greatly reduced in soybean seeds, treated with a polyvinylidene chloride copolymer emulsion (daran), after 2 months storage at 85% relative humidity. The material was applied either at rate of 8 g/ kg seed with a Gustafson Batch Laboratory Treater, designed to coat small samples of seeds with agricultural chemicals, or at 50 g/ kg with a Vector/Freund Hi-Coater, designed to coat pharmaceutical tablets. The latter treatment provised a more effective moisture barrier. Seed germination was greatly reduced when measured immediately after encapsulation, but after storage for 2 monthsat 85% relative humidity, it was similar to that in the untreated control lots. Daran, applied to maize seeds at 50 g/ kg in the Vector/Freund apparatus, was an ineffective moisture barrier. The fungicide thiabendazole, however, controlled storage fungi and prevented loss in germination potential. Scanning electron micrographs revealed flaws in the integrity of encapsulation coats that could be related to application methods. |
