1975年4月至12月，对休伦湖南部表层水体叶绿素生产的潜在营养限制进行了月度测定。根据实验室培养的叶绿素在季节性变化的光照和温度条件下产生的叶绿素，确定了浮游植物对营养物质丰富的自然组合响应。实验处理包括含有磷、氮、硅、EDTA、维生素和微量金属的完整处理；从完整处理中删除的处理；不同磷浓度的完全处理；以及单一营养添加的处理。当磷、EDTA、FeEDTA、维生素和硅同时添加时，效果在夏季和秋季最为明显。磷和其他营养物质的添加所产生的影响的强度因季节而异。单独添加EDTA、N和Si几乎没有影响，从整个处理中删除N也是如此。单独添加磷会导致有限的生长。从复合体中删除磷...
Potential nutrient limitation to chlorophyll production in surface waters of southern Lake Huron was assayed monthly from April to December 1975. Natural phytoplankton assemblage responses to nutrient enrichment were determined from chlorophyll production in laboratory incubations under seasonally varied light and temperature conditions. Experimental treatments included a complete treatment containing P, N, Si, EDTA, vitamins, and trace metals; treatments with deletions from the complete treatment; complete treatments with different P concentrations; and treatments with single nutrient additions. Effects were most pronounced during summer and fall when P, EDTA, FeEDTA, vitamins, and Si were added simultaneously. The intensity of the effect resulting from additions of phosphorus and other nutrients varied seasonally. Individual additions of EDTA, N, and Si had little effect as did deletion of N from the complete treatment. Addition of P alone resulted in limited growth. Deletion of phosphorus from the comp...
