Abstract:
:Seed number per pod is negatively skewed in Leucaena leucocephala. Post-fertilisation abortion of pods does not completely explain the skewed distribution. It is shown that a pre-fertilisation regulation effectively restricts the formation of pods with less than a certain number of seeds. The regulation is rendered through the inhibition of pollen grain germination by the stigmatic fluid when the pollen grain is less than a certain critical load in the stigma. Such a control is shown to have implications in the evolution of pollen package units, generation of male gametophytic competition and the economy of packing seeds in pods.
