    Abstract

    Germination of 15 groundnut cultivars and 7 pearl millet [P. americanum] cultivars at constant temp. between 0 and 50°C was studied on a thermal gradient plate. Large differences in germination rate and percentage germination were observed in both species. Base temp. ranged from 8.0 to 11.5° in groundnuts and from 8.0 to 13.5° in pearl millet; optimum and max. temp. for germination were 29.0-36.5° and 41.0-47.0°, resp., in both species. The results are discussed in terms of adaptation to high soil temp. and crop establishment in the semiarid tropics
