Résumé:
Com (Zea mays L.) is one of the most cultivated crops in the world. In Brazil,
this cereal has wide range of use. Most áreas where there com production is
used to turn irrigation if not performed correctly becomes predominant for the
salinization of the soil. Thus, the aim with this study was to evaluate the effect of
foliar application of proline in growth and com grown in soil physiology with
different leveis of salinity. The experiment was conducted at the Science and
Technology Centre Agrifood (CCTA), belonging to the Universidade Federal de
Campina Grande (UFCG), Pombal, PB, from March 30 to April 30, 2015, using
a variety AG 1051. The treatments consisted of two leveis of soil salinity (EC
3.26 and 0.86 dS/m) and ave proline concentrations (0, 2.5, 5.0, 7.5 and lO
mmol L') applied to the leaves on com plants. The experimental design was
completely randomized in a factorial 2 x 5, with four replications. The higher
values for physiological parameters were observed when using the least saline
soil (EC 0.86 dS/m). For the growth variables in plants, the highest average
observed occurred when it was used the concentration of 7.5 mmol proline L''.
