Phenotyping of flora of Svalbard by vibrational spectroscopy of pollen and seeds

Svalbard is an isolated archipelago characterized by an arctic climate, permafrost and scarce vegetation adapted to extreme conditions. The islands have rather rich flora in relation to its high latitude, dominated by mosses, forbs, graminoids and prostrate shrubs. The growing season in the Arctic is very short, so the anticipated rising temperatures and an extended growth season could have large consequence on the domestic species. Changes in plant genotype, phenotype and phenology are expected as response to the selection pressure of climate change.

Due to unique habitat, plant populations of Svalbard present a perfect experimental pool for investigation of reproduction fitness and strategies in the extreme environment. The fieldwork in Svalbard has covered two separate periods: 1) sampling of pollen belonging to plant (predominantly Poales) populations in the Isfjorden area in mid-July, and 2) sampling of seeds, from the same plant populations in early September. Biochemical composition of pollen and seeds will be determined by vibrational spectroscopy in order to assess acclimation and adaptive reproductive traits of Svalbard’s plant populations.
