Abstract

THE occurrence of spontaneous1, as well as induced2, haploidy has been observed in several plant genera. Haploidy has been reported in cultures from secondary phloem tissue of carrot3, and haploidy and somatic pairing have also been noted in cultured stem tissue of Haplopappus gracilis4. Recently, haploid cells were observed to occur spontaneously in leaf primordia of young seedlings of Haplopappus gracilis5. The purpose of this communication is to report spontaneous reduction in the number of somatic chromosomes in the root meristem of Haplopappus gracilis.
