Study of Pollen Fertility of the Genus launaea from Pakistan

Sohail Jamil Qureshi, Abdul Ghani Awan, Mir Ajab Khan and Sofia Bano

Abstract:
Pollen fertility of seven different species, Launaea secunda, L. acualis, L. aspeliniifolia, L. capitata, L. procumbens, L. residifolia and L. secunda belonging to genus Launaea of family Asteraceae was studied from Pakistan. Morphology of pollen grains of each of the species is based on specimens selected at random. At species level, micro-morphological characters like pollen fertility differences and distribution of surface pattern, shape and size of pollen have been considered found to exist. Pollen fertility data shows that L. residifolia is having the highest value 98.84 while the least value was found in the Launaea acuais 78.41%. Further cytological studies are required in taxonomy to determine the fertility status in different species. This study demonstrates the potential of pollen studies in distinguishing some taxonomic groups in the Asterasceae.
