In the biennium 1981-82, an experience of leaf blade and awn removal was carried out during grain filling at different times on four durum wheat varieties and six triticale genotypes. The removal of all leaf blades reduced kernel weight proportionally to the kernel growth stage when the removal of the assimilant leaf surface occurred. Weight reduction resulted to be influenced furthermore by the intrinsic factors characteristic of the species and variety as well as by water availabality in the soil. The loss, more or less anticipated, of leaf blades caused unit-weight decreases up to 25% in late lines, while no remarkable unit-weight variations were recorded in early cv. if the assimilation surface reduction occurs when kernel is almost completely formed.
