Abstract

In 1982 the seasonal changes of leaf Ψ, Ψsand Ψpof five durum wheat cultivars grown under field conditions was monitored using a psycrometric apparatus. There was found to be a general increase in pressure during the floreal differentiation-earing period. No particular differences were observed either between the tall and dwarf varieties or between those with bloom or not. The relation between the values ot Ψpand leaf Ψ, taken from the earing period to the inltial stage of leaf senescence das not fallow a linear regression in all the varieties. According to an analysis of the differing values of Ψpand Ψ, it seems that the varieties «Tibula» and «Creso» are more resistant to water stress than the other varieties, although these findings require further convalidation.
