Abstract
Two-year-old macadamia seedlings were used as experimental material to study their photosynthetic characteristics under phosphorus stress.The results showed that the contents of chlorophyll a and b,total chlorophyll,and the ratio of chlorophyll a/b reduced when these seedlings were under phosphorus stress.Net photosynthetic rate,stomatal conductance and water use efficiency reduced and intercellular CO2 concentration and transpiration rate increased under phosphorus stress.
