1.在Ca ~（2+）浓度为0.005M ~ 0.02M范围内，随着Ca ~（2+）浓度的增加，单轴骨针的长度、生长速率和产量逐渐增加。在0.04 M Ca ~（2+）海水中，结果与海水（0.01 M Ca ~（2+））相差不大，骨针趋于畸变。2.此外，diamox，浓度范围从10-7至10-4 M，逐步抑制骨针的形成，长度，宽度，生长速度和生产率都受到影响。 在10-3 M diamox中完全抑制。3.将幼年海绵放回海水中导致正常骨针的形成。
1. The length, growth rate and production of monaxon spicules increased progressively with Ca2+-concentration from the threshold (about 0.005 M) to 0.02 M. In 0.04 M Ca2+-sea-water, however, the results differed little from those for sea-water (0.01 M Ca2+), and the spicules tended to be aberrant. 2. The addition of diamox, in concentrations ranging from 10-7 to 10-4 M, progressively inhibited spicule formation; the lengths, widths, growth rates and production rate were all affected. Inhibition was complete in 10-3 M diamox. 3. Returning the juvenile sponges to sea-water resulted in normal spicule formation.
