title: [The sperm of Equisetum arvense L. I. Ultrastructural and cytochemical studies of nuclear constituents of the ripe sperm].
abstract: Several ultrastructural cytochemical methods are used to determine the constituents of the ripe nucleus of Equisetum arvense L. They show that: DNA, associated with an arginine-rich histone, is localized in central region of the nucleus; nucleoplasm is reduced to a thin peripheral coat and contains a probably lysine rich histone; RNA is not detectable; non histone proteins form lenticular amounts disposed against the nuclear membrane.
