Summary
Samples of Eichornia crassipes (MART.) SOLMS were collected from the New Braunfels to Gonzales reach of the Guadalupe River, Texas. Plants were also cultured in the laboratory in media containing varying amounts of nitrate and phosphate.
The nitrogen and phosphorus content of the blades, floats, and roots of the plants was determined and the values were compared with the nitrogen and phosphorus content of the water in which they were growing.
The data show a positive correlation between the nitrogen and phosphorus content of the waterhyacinth tissues and the nitrogen and phosphorus content of the environment. Values obtained on plants cultured in the laboratory suggest that luxury nitrogen and phosphorus may be stored in the floats.
Results reported here support the suggestion that the technique of tissue analysis has considerable potential for assaying the nutrient status of lakes and streams.
Zusammenfassung
Eichornia crassipes (MART.) Solms wurde in dem Guadalupe in der Gegend von New Braunfels und Gonsalez gesammelt. Einige Pflanzen wurden auch im Labor in verschiedenen Nitrat- und Phosphatkonzentrationen gezogen.
Der Nitrat- und Phosphatgehalt der Blatter, Schwimmblasen und Wurzeln wurde festgestellt und mit der Nitrat- und Phosphatkonzentration des Wassers verglichen.
Die Ergebnisse weisen auf ein positives Korrelat zwischen dem Nitrat- und Phosphatgehalt der Wasserhyacinthe und dem des Wassers hin. Resultate von Laborpflanzen deuten auf eine mögliche Speicherung der überflüssigen Nitrate und Phosphate in den Schwimmblasen.
Die Ergebnisse schlagen vor, Bass die Technik der Gewebeanalyse beträchtliche Möglichkeiten hat, die Nahrhaftigkeit von Seen und Flüssen zu untersuchen.
