pollinated hybrid



Before discussing the various pollination , it never hurts to know what it is pollinated . Pollination ( pollinatio ) is the fall of pollen on the stigma ( for a closed group seed plants ) or fall pollen directly on the ovule ( for the naked seed plants ) . Pollination synonymous with fertilization . Pembuhan is the marriage ( being the union or pelemburan ) egg cells contained in the biological institute in the ovule with a core derived from pollen .

Based on the origin of pollen that fell on the stigma , pollination can be divided into several types, namely :
a. self-pollinating
Self-pollination is often called autogamy if pollen falls on the stigma comes from the flower itself .

b . pollination neighbors
Neighbor pollination or geitonogamy is often called pollination occurs when pollen falls on the stigma of another flower comes from the same plant .

c . cross pollination
Cross-pollination ( allogamy , xenogamy ) is pollination occurs when pollen falls into the stigma comes from the flowers of other plants , but still belong to the same type .

d . pollination hybrid
Hybrid or hybridogamy pollination is pollination occurs when pollen falls on the stigma comes from another flower on a different plant species, or at least have a different nature .

Well that's 4 kinds of pollination by native pollen falling on the stigma .
