Enzymic activities and galactomannan mobilisation in germinating seeds of fenugreek (Trigonella fœnum-graecum L. Leguminosae) : Secretion of α-galactosidase and β-mannosidase by the aleurone layer.

abstract：:Primary roots of Lepidium sativum (L.s.) grew upwards in glass capillaries in order to prevent mechanically the geotropic curvature. The central cap cells (statocytes) were investigated with regard to the polar arrangement of their organelles. After 20 minutes of inversion, which correspond to the latent period of L.s...
