Ecological studies on some aquatic fungi of Gorakhpur, India

  • G. C. Srivastava
Article

Summary

The distribution of aquatic fungi in six waters of Gorakhpur, ranging in pH from 5.6–8.8 has been studied from April 1963 to March 1964. The thirty species collected during this study belong to Blastocladiales, Saprolegniales, Lagenidiales and Peronosporales. These have been placed in three groups: acid, alkaline and neutral according their tolerance of hydrogen-ion concentration.

A distinct seasonal variation in occurrence of these species has been noted and though the individual periodicity patterns vary, the low temperatures of winter months (about 18°C) are most suitable for growth of most of the species.

Résumé

La répartition du mycète aquatique dans les eaux de Gorakhpur (Inde) ayant pH d'ordre 5.6 à 8.8 a été étudiée depuis l'avril 1963 jusqu'á mars '64. Les trente espèces, recueillies pendant cette étude, appartiennent aux families Blastocladiales, Saprolegniales, Lagenidiales et Peronosporales. Selon leur tolérance de la concentration d'ion d'hydrogène elles ont été groupées — acides, alcalines ou neutres.

Une variation périodique très nette en rencontre de ces espèces est observée et bien que les modèles de périodicité varient, les températures peu élevées (environ 18°C) d'hiver sont les plus favorables pour la croissance de la plupart des espèces.
