Abstract：
:This study compared the behaviour of six autochthonous pear millet ecotypes collected through the Tunisian territory under salt stress from germination to maturity. It showed that salt has little effect on germination rate and coleoptile emergence. However, this effect is more significant for radicular growth and between ecotypes. Salinity did not influence plant height, which seems to be a varietal characteristic, but revealed a positive effect on the foliar expansion. On the productivity level, salinity did not exert a prejudicial effect over the length of the principal candle, but improved the yield component. This adaptation to salinity is mainly due to its root system. This effect varied according to stress intensity and ecotype. Vegetative growth and yield of high-straw ecotypes was decreased by severe salinity, while ecotypes with low or medium height appear very stable on the productivity level. Such ecotypes can play an important role in the conservation and development of fragile grounds, and also be useful as a source of desirable genes for genetic improvement in salinity conditions.
