The Newman method, modified for the estimation of the total thallus length of filamentous algae
Provedor de dados: Open Marine Archive
Autores: Gillis, J.
Newman's (1966) method of total root length estimation is modified and adapted to measure total length of filamentous algae in culture (i.c. &lt;i&gt;Polysiphonia&lt;/i&gt;). This method makes possible a measurement and an estimation of the growth of the algae in culture without disturbing them. The petri dishes are placed on a 1x1 mm grid and the filament/grid intersections are counted. Total filament length (T) is given by T = Pi N (LxW)/4(LxW), with N = the number of intersections, L = the length and W = width of area in which the thallus is situated. Total filament length of &lt;i&gt;Polysiphonia&lt;/i&gt; in culture estimated by the Newman method is compared with camera lucida measurements. The correlation between the results obtained by the 2...
