Abstract

Aspects of age-related changes occurring in the blade/sheath junction of leaves ofLolium temulentum L. were studied using autoradiography, light and transmission electron microscopy. With increasing leafage the apical transport of sheath-applied radioactive amino acids was retarded at the sheath side of the blade/sheath junction. An anatomical study revealed the presence of tyloses in the protoxylcm lacunae of vascular bundles at this region in senescing leaves. The possible involvement of tyloses in grass leaf senescence is discussed.
