Carrot seed germination in different conditions of salinity and temperature

The success of the germination process depends on the entry of water through the tissues that enclose the embryo. The presence of salts reduces the gradient between the ground and the surface of the seed, restricting the absorption of water by the seed. The objective of the experiment was to evaluat...
