This research determined constants for a viability equationto predict the longevity of groundnut seeds and to improve themanagement of seedlot storage throughout the trading period.Seeds of the Brazilian cultivar Tatu (Valenciabunch type) were tested. Nine moisture content levels (rangingfrom 2.4 to 12.8%) and three storage temperatures (40, 50 and65 °C) were used. Sub-samples for each moisture content-storagetemperature combination were sealed in laminated aluminium-foilpackets and stored in incubators until complete survival curveswere obtained. A reliable equation was obtained to predict groundnutseed longevity through the constantsKE=6.177,CW=3.426,CH=0.0304andCQ=0.000453.Copyright 1998 Annals of Botany Company Arachis hypogaeaL., seed longevity, seed storage, viability equation. 相似文献
