Abstract:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. Seeds can only be produced when pollen is transferred between flowers of the same species. Pollination being a process of sexual reproduction helps to maintain plant characters. The dioecious nature of nutmegs has long been a problem for nutmeg cultivation, because while some male trees are needed for pollination, only female trees produce the cash crop. In clove viable seeds have not been produced from selfed flowers, indicating that the flowers require cross- pollination. The type of pollination in cambodge is cross pollination through Anemophily. Characteristics of pollen grains revealed the chance of wind pollination. Protogynous dichogamy in cinnamon leads to cross pollination. Tamarindus indica is a highly cross-pollinated crop and the pollination is through entomophilous and implicated ants particularly red ants. Common Juniper is dioecious in nature, predominantly cross pollinated. Wind pollination plays an important role in common juniper. Knowledge of pollination in tree spices is limited and is important with respect to crop improvement, production and biodiversity in tree spices. Most of the tree spices are cross pollinated thus increasing variability in population and provides chances for the evolution of new varieties and species and also pollinators in creating diversity among them.
