Summary: The effects of three levels of water in the soil (35%, 65% and 95% of the total volume of pores taken by water) before and after severe water stress were studied in three cultivars of wheat (Triticum aestivum L.) (IAC-18: Xavantes; IAC-21: Iguaçu; and IAPAR-1; Mitacoré) during tillering and flowering stages to observe the occurrence of osmotic adjustment in the leaves. All three cultivars showed leaf osmotic adjustment in both stages after severe water deficit. A better osmotic adjustment was observed when the water deficit was applied more slowly. IAPAR-1 showed the least osmotic adjustment with only - 1.82 bars difference in relation to the control, and IAC-21 had the greatest difference (-4.33 bars) compared to the control.

(IAC-18: Xavantes; IAC-21: lguaçu e IAPAR-1: Mitacoré), durante os estádios de perfilhamento .e floração, a fim de se observar a ocorrência de ajustamento osmótico nas folhas. Todas as cultivares apresentaram ajustamento osmótico nas folhas, nos estádios de perfilhamento e floração após severo estresse hídrico. O maior ajustamento verificou-se nos tratamentos em que o estresse hídrico ocorreu mais lentamente. Dentre as cultivares, IAPAR-1 foi a que evidenciou menor ajustamento osmótico, apresentando uma diferença de -1,82 bars, em relação à testemunha (não estressada) e IAC-21, a de maior ajustamento, com uma diferença de -4,33 bars.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVilela, Enivanis de AbreuMorães, José Antônio P.
