Effects Of Nutrients On Productivity And Morphology Of Typha Angustifolia X Latifolia, V. Bonnewell, D. C. Pratt

Journal of the Minnesota Academy of Science

The productivity of natural stands of cattails (Typha latifolia) has been correlated with the amounts of nutrients in the soil and water by Boyd and Hess (Ecology, 51: 296, 1970). The direct effects of varying levels of nitrogen (N), phosphorus (P) and potassium (K) on productivity were examined in our study by growing cattails in Hoagland's nutrient solution. Concentrations of ¼, 1/16, and 1/64 the amount of N present in complete Hoagland's solution (0.01Ml resulted in 63 percent, 48 percent and 26 percent of the dry weight of plants grown in complete solution. Rhizomes used to start plants contained considerable …
