Abstract:
Studies were undertaken on the mechanism of anthesis in Indian lemongrass.
An inflorescence takes 25 to 32 days for completion of anthosis. The
peak period of anthesis is from the 6th day from commencement of anthesis
to the 11th day. About 80% of spikes complete anthesis by the 15th day.
Anthesis takes place in the morning between 7 and 8.30. !n the sessile spikelets
anthesis appears earlier than its appearance in the pedicellate ones. There
are four distinct stages in the anthesis of sessile spikelet which take plrce
one after the other in quick succession. The most characteristic featrue of
anthesis is the slight protogynous nature of the sessile spikelet. Though this
is a basic adaptation for cross pollination, the large number of spikeleis opening
in a short span of time indicate the possibility for self pollination under
field conditions.
