摘要:

Nutrient limitation of growth of the algal community in Lake Horowhenua was assessed by: reference to nutrient concentrations; short‐term physiological assays, which indicate nutrient deficiencies in algae; and a laboratory growth assay where the algal community responds with chlorophyllaproduction over a period of 4 days on relief of shortage of the limiting nutrient. Shortage of phosphorus limited algal growth during winter months whereas nutrient nitrogen shortage restricted growth in summer.
