The occurrence of large rainfall in the course of the ripening cycle has led to higher grain yield, mealiness and P-acid soluble fraction in semolina but has reduced both protein and gluten content as well as the lipidic and nucleic P-fractions. The early maturing cultivars yielded semolina with larger amount of P-acid soluble and P-nucleic fractions; the semolina obtained from high tillering cultivars contained lower quantity of gluten and more P-acid soluble fraction. In considering the role of metabolically active P-compounds, it appears that to earliness is correlated both the more intense phosphatic nutrition, as revealed by the higher P-acid soluble content, and the more active protein biochimism, as can be deduced from the larger amount of P-nucleic fraction in the kernels T2 - Agrochimica ER -
