Abstract:
The present study was carried out at Kerala Agricultural University to understand the flowering phenology of Alpinia galanga (L.) Wild. Genotypes maintained at ICAR-NBPGR Regional Station, Vellanikkara. Observations were recorded from nineteen accessions, from flower bud emergence to fruit ripening. Results indicated that there are four principal growth stages from flower bud emergence to seed maturity, which were coded according to the BBCH scale. As per the observations, there are two Flowering seasons from May to July and September to October months. Flower bud initiation to complete flower opening in panicle took 35 days and from fruit set to ripening it took 180-185 days. The studied population of Alpinia galanga had two phenotypes, one group expressing cataflexistyly and the other showing anaflexistyly, which is not reported in the species so far. This study also provides complete information regarding the phenological growth stages of Alpinia galanga from flowering to seed maturity.
