Abstract

Meiotic cells and chromosome:, of the native the and giant ipil-ipil were observed and compared using the aceto-carmine squash technique. Qualitative and quantitative analyses of the cells during interphase and first meiotic division stages namely : prophase, pachytene, diakinesis, metaphase, anaphase and telophase revealed that a difference exist between the native and giant varieties of L. leucocephala. The meiotic cells of the giant varieties are larger except for those in metaphase I, anaphase I and telophase I. Statistical analyses, however showed a significant difference existing only between the interphase, pachytene and diakinesis cells of the two types. The native varieties have higher percentages of meiotic and nucleoplasmic indices. The chromosomes behaved normally in all the stages of meiosis.in both types. At diakinesis, a common diploid number of 52 was observed. The giant varieties have larger chromosomes than the native varieties.
