Leachate collection systems and
zoospore collection vessels under arrays of 42, top, and 21, bottom, #1 container plants.
They also found that the cultured symbiotic algae could form flagellated, motile
zoospores under certain conditions (Rahat and Reich, 1991).
Effect of temperature on germination of
zoospores of Phytophthora drechsleri f.sp.
We evaluated the development of sporangia and
zoospores in sporulation medium (see above).
The
zoospores absorb its own tail, forming a resting spore.
"The mature potato foliage and stems can easily act as dangerous sources of
zoospores, which will drop off or are washed off on to the soil through which the tubers will be lifted.
(1996) discussed the relationship between reproductive responses and resources, and Reed (1987) reported a strong relationship between biomass and
zoospore production; because our treatments induced differences in growth, we hypothesized that there should also be differences in reproduction.
Sporangia of all Phytophthora species, when mature, contain a variable number of motile, biflagellate
zoospores (fig.
Zoospore ([approximately equal to] [10.sup.4] zoospores/ml) of Saprolegnia sp.
Numerous kills were reported in the Chesapeake and North Carolina estuaries through 1998 in association with Pfiesteria-like
zoospore concentrations of 600-35,000 cells/mL water (Glasgow 2001).
"The latest blight reports also recommends using products with known
zoospore activity.
sojae mycelial growth or to
zoospore germination was demonstrated in vitro (Bhattacharyya and Ward, 1985).
