5. Variants occur frequently in Helminthosporium spp. either in the form of sectors or " patches." Although H. sativum race 1 has been cultured for 17 years, it still gives rise, under certain conditions, to numerous variants of different types. 6. Potato-dextrose agar rendered stale by ...
However, leaf tissues showed a greater diversity of endophytes and Drechslera, Curvularia, Bipolaris, Alternaria and Aspergillus spp. were the dominant fungi... RN Kharwar,VC Verma,G Strobel,... - 《Don Curr Sci》 被引量: 113发表: 2008年 Diseases caused by Bipolaris sorokiniana and Drechslera...
Spindles from sugarcane ( Saccharum spp. hybrid) tissue were challenged using labeled Helminthosporium (Bipolaris) sacchari toxin to determine the general effect on different organelles and structures. Toxin labeling was characterized by biochemical and physiological behaviour of the fungal pathogen (dry ...
The desirability of distributing graminicolous Helminthosporium spp. in the genera Drechslera and Bipolaris [cf. 39: 464] is considered doubtful. As H. is ... CV Subramanian,BL Jain - 《Current Science》 被引量: 55发表: 1966年 Growth, sporulation and conidial characteristics of five graminicol...

Concentric zonation in colonies of Helminthosporium spp., with special reference to H. rostratumConcentric zonation in colonies of Helminthosporium rostratum Drechsler on solid media was of three main types, these being due to alternation of (A) aerial mycelium with appressed mycelium, (B) mycelium ...

Actinomycete-fungus antagonism has been demonstrated for a wide variety of plant pathogens, such as Alternaria =-=(9)-=-, Rhizoctonia (26, 35), Verticillium (42), Fusarium (36), and Macrophomina (17) spp. Moreover, actinomycetes of the genus Streptomyces have been used to commercially ...

The most antagonistic fungus was Aureobasidium pullulans, followed by the Sporobolomyces spp. group and then the "White yeasts" (mainly Cryptococcus spp.). There was considerable variation in inhibitory activity within each group on agar. Isolates of Cladosporium spp. did not show any antagonistic...
