Outline of Final Research Achievements

Salicornia herbacea exhibited better growth in sandy soil compared with in paddy soil. Maximum dry weight of Salicornia shoot was observed in sandy soil; it was 1.1 kg m-2. The seeds and shoots contained fatty acids (total amount of palmitic acid, margaric acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid and behenic acid) in a dry weight amount of 5% and 0.9%, respectively. The fatty acid production potential is estimated to be 9.9 g m-2, though an accurate estimation could not be performed because seeds had large shedding habit. From the perspective of environmental restoration of salinity-polluted soil, it is estimated that 168.3 g of Na is removed from salinity-polluted soil per square meter due to the fact that the Na content per plant was 15.3%.
