Review: Pollination, Pollinated and Pollinators Interaction in Pakistan

open access: yesJournal of Bioresource Management, 2014
The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms.
