The use of nutrient bioassays to assess the response of Eucalyptus grandis to fertilizer application. 1. Interactions between nitrogen, phosphorus, and potassium in seedling nutrition

, : The use of nutrient bioassays to assess the response of Eucalyptus grandis to fertilizer application. 1. Interactions between nitrogen, phosphorus, and potassium in seedling nutrition. Canadian Journal of Forest Research 23(1): 1-6

The nutritional requirements of Eucalyptus grandis Hill ex Maiden seedlings were studied in glasshouse pot experiments. Nitrogen (N), phosphorus (P), and potassium (K) demand was assessed by bioassays, in which the uptake of tracers (15N, 32P, or 86Rb) by roots excised from the seedlings grown at different levels of nutrient supply was measured. A pilot study showed that there was an inverse relationship between nutrient supply and influx. The measured influx was affected by the length of time that the roots were stored before the bioassay was applied. In a 3(3) N, P, and K factorial nutrient experiment, growth was primarily influenced by N. Maximum growth occurred at the highest level of supply of each of the three nutrients. N and K influx in the root bioassay was inversely related to foliar N and K concentration, but P uptake was not related to foliar P concentration. These results indicate that the root bioassays are more sensitive determinants of nutrient limitation than foliar analysis. Interactions between N and P and between N and K alter the stem:leaf ratio, which may be of importance in optimizing wood production.

In an investigation conducted in 1957 on 348 eggs from a Partridge Leghorn x White Leghorn cross, shell thickness was found to average 0.339 mm. at the blunt end of the egg and 0.356 mm. at the pointed end. In a later study on 661 eggs of the same...

A study using a lifetime physical activity questionnaire investigates a correlation between exercise and functional status as evidenced by six-minute walk distance. Recent studies have shown strong associations between chronic exercise and improved spirometric values. Building on these findings, we investigated whether habitual lifetime exercise influences six-minute walk test performance (6MWT) in subjects w...
