Abstract
Five defense barriers composed of fluorescent compounds can be located on the surface of the seed, seed coat tissue, remaining endosperm, surface of the embryo, and embryo tissue.
Membrane damage in aging seeds and dead embryos can be responsible for leakage of fluorescent compounds.
Phenolic compounds precipitated with caffeine were located in very small vesicles inside the cytoplasm, ER and nucleus during embryogenesis, and with seed maturation an additional compartment appeared — space between the plasmalemma and the cell wall, from which, after three hours of germination, phenolic compounds moved to the surface of the radicula.
New large deposits were formed after 24 h of germination.
Aging involved membrane damage and precipitation of ground cytoplasm.
