生长在Poturnogeton richarclsonii上的附生植物在生物量（如叶绿素a）和光合速率方面与生长在形态相似的塑料植物上的格隆1 r1 g相似。在1976年和1977年的生长季节，单位面积的产量。碱性磷酸酶活性！人工基质上的附生植物的nrl磷限制指标始终较高，这表明真实的植物向其附生植物转移少量营养。然而，具体的生产力的附生植物（生产每单位的叶绿素）是没有显着不同的OII的两个基板。这些相似之处几乎不支持植物和附生植物之间共生或共生的假设。活的植物似乎是一个中立的

Epiphytes that grew on Poturnogeton richarclsonii were similar to those gron 1r1g on Inorphologically similar plastic plants in both biomass (as Chl a) and prinlar! production per unit area, over the growing seasons of 1976 and 1977. Alk* 1’ d ine phosphatase nctivit! , nrl Indicator of P limitation, was always higher for epiphytes on artificial substrates, which suggests that real plants transfer a small amount of nutrient to their epiphytes. However, specific productioll of the epiphytes (production per unit of Chl) was not significantly different OII the two .ubstrates. These similarities give little support to the hypothesized sy tnbiosis or cotllpetition between plant and epiphytes. The living plants appear to be a neutral
