Cytological, Foliar-epidermal and Pollen Grain Studies in Relation to Ploidy Level in Four Nigerian Species of Physalis L.

The relationship between the chromosome numbers, pollen grain and epidermal parameters and ploidy levels among four Nigerian Physalis species (Physalis angulata, Physalis micrantha, Physalis pubescens and Physalis peruviana) was investigated using morphometrics, meiotic chromosome studies and palynology. The study revealed that P. angulata has chromosome number of 2n=48 while the other three species have chromosome number of 2n=24 each. The chromosomes were well paired at pachynema as ring II or rod II. Two simultaneous cytokinesis were observed in all the four species studied. P. angulata has the widest pollen grain diameter as well as largest guard cell area and highest Stomata Index when compared to the rest. The results indicate that P. angulata is the only tetraploid among the four Nigerian Physalis species studied while the other three are diploids.
