In previous chapters we have set down, with some discrimination, the contributions to the record of structural aspects of morphogenesis in the watermolds. Only in passing have we touched upon the factors that trigger or modify the genetically dictated form these fungi may take. This and the following three chapters review the literature dealing with external and internal factors that influence ...

Abstract The leaf extract of C. alata showed antifungal activity by inhibiting five pathogenic fungi. Saprolegnia sp. attack was one type fungus that inhibits the hatchability eggs. leaves also can inhibit growth fungi on gouramy objective this study to determine effect and optimal concentration Cassia L. hatching rate, time, prevalence, survival silver barb eggs ( Barbonymus gonionotus ) infec...

The first recognizable mention of spores in the Saprolegniaceae is in Gruithuisen’s account (1821:445, pl. 38, figs. 14-16) of “seeds” in “compartments” at the ends of filaments of “Conferva” ferax. Hannover’s exposition (1842) of the nature of spores and spore discharge in a watermold was far more detailed: records of daily observations on motility, encystment, and germination. It was Unger (1...
