Effect of saline stress on the growth of "Tayuyo" maize seedlings under in vitro conditions

Corn is one of the most economically important cereals in the world, ranking second after wheat. Among the great diversity of varieties of Zea mays L. that are cultivated in Cuba, is the "Tayuyo" variety. Currently, there are no studies that evaluate t...
