Abstract

A study of the cytology of endosperm ofPisum sativum, pea, fixed at different stages of development reveals that it remains free nuclear throughout its entire life. The nuclei are extremely polymorphic and differ in size from each other. The nuclei increase proportionately in size with the advancement in endosperm age.

The haploid chromosome number of the taxon was verified asn=7. The endosperm nuclei were normally triploid with 3n=21 chromosomes, but higher polyploidy (6n and 12n) and aneuploidy were also recorded in small proportions. Nuclear fusions and aberrations such as irregular separation of chromosomes, sticky bridges and laggards are believed to be responsible for the origin of polyploid nuclei.

Accumulation of mitotic aberrations including bridges and laggards are considered to result in reduced divisional activity thereby leading to endosperm breakdown with the consequent low seed set in some cases.
