DrSr Kochuthressia K P PG Department of Botany pollination Pollination  is the transfer of  pollen   from a male part of a plant to a female part of a plant later enabling  fertilisation.

Many documented trial results are available that demonstrate that well managed pollination can increase yields of macadamia. Pollination. Pollination. is the transfer of pollen from the male anther to the female stigma.. Importance of Pollination. Sexual reproduction is important for evolution as it produces variable offspring, creating diversity and variation among populations (shuffling of genes).. Ways of pollination. Self Pollination.
