Effect of chlormequat chloride on four wheat cultivars on two sowing dates

Two experiments were conducted aiming to evaluate the effects of the growth regulator CCC [2-Chioroethyl,trimethylammonium chloride] on seed yield and other characteristics of four wheat cultivars on two seeding dates. The treatments were the cultivars CEP 19, BR 14, BR 15 and BR 23 and the CCC doses 400 and 1000g ai/ha in 1989 and 1990 respectively. The seeding dates were in June and July. The only effect observed was a reduction in plant height but there was no increase in grain yield. It was concluded that further studies showld be carried out in order to determine the factors that affect the response of the wheat plant to this growth regulator.
