Seeds of two Brazilian varieties of dry beans, Rosinha and Carioca, were stored at 20o and 30oC and 75% R. H. The progress and extent of deterioration during storage was evaluated by means of standard germination, accelerated aging, root growth, tetrazolium and chemical soak tests. Seed of both varieties were also adjusted to 13.8% moisture content, sealed in glass containers and rapidly aged at 45oC to obtain different deterioration or vigor levels. Three vigor levels--high, medium and low--were selected for field performance studies on the basis of rate of root growth and response to accelerated aging treatments. In the storage studies loss of vigor was manifested by a reduction in average root length, a lowered resistance to accelerated aging, an increased permeability of cell membranes, and a reduction in enzymatic redox activity. Loss of vigor preceded a decrease in viability under both storage conditions. Results of field tests indicated that the consequences of planting low quality bean seeds were slower emergence and early seedling growth, reduced stands, less uniformity in plant growth, late flowering, and decreased yield. Of the quality tests evaluated, root growth and tetrazolium reaction were most efficient in detecting the extent and rate of deterioration during storage. Accelerated aging was most effective in predicting the storability of the two lots and in monitoring the progressive loss of vigor. |
