Is There Ecological Adaptation in Coconut Nursery Seedlings Stage? a Preliminary Investigation
Year: 2010
Type: article
Abstract: Seedlings were raised in three, nurseries representing different agro-ecologicalregions, to. test whether growing seedlings exhibited adaptation to a particularenvironment. Seed nuts were also selected from agro-ecologically different regions.The T x T seed nuts from the Isolated coconut seed garden showed a faster rate ofgermination at all sites compared to Moorock seed nuts (from the North Westernregion) or Dehigahalande seed nuts (from the Southern region). The vigor ofseedlings (a qualitative assessment based on the number of vigorous seedlingsselected) was enhanced by a good soil water supply during the early nursery stagescombined with a higher level of solar-radiation at the nursery site. There was nointeraction between the source of seed nut and site of nursery indicating the absenceof manifestation of ecological adaptation at the seedling nursery. The quality of theseedlings was enhanced by adequate soil water and high level of solar radiation onthe nursery' beds. The subsequent performance, of these seedlings would havefollowed up after field planting to confirm the assumptions on adaptation discussed.
