elonging to the genera of Choanephora, Diaporthe, Myrothecium, Fusarium,
Corynespora, Colletotrichum, Botryodiplodia, Phoma, Phyllosticta and
Rhizoctonia. Two species of fungi, Didymosphaeria donacina and Nodulisporium
sp. isolated from soybean were new records. In the case of mungbean, among 25
species of fungi isolated, 9 were pathogens and belonged mainly to the same
genera as those found on soybean. The percentage of pathogenic species to the
total seed mycoflora also showed similarity, in that they ranged from 3b-40%.
The results emphasizes the need for regular seed health testing and adoption of
stricter quarantine measures in the import and movement of legume seeds.

There was a marked increase in free fatty acids and reducing sugars and
decrease in protein content due to Colletotrichum capsici, Rhizoctonia solani,
Phoma exigua and Alternaria alternata infection of mungbean seeds in storage.
There was a sharp rise in total phenols which, however, decreased in the later
phase of incubation. [AS]

Freshly harvested seed samples of mungbean and blackgram were stored for
one year in bamboo paper bags under laboratory conditions. The storage
mycoflora was investigated after 60, 120, 180, 240, 300 and 360 days of storage
by routine mycological techniques and screened for pre- and post-emergence
mortalities. The paper lists the mycoflora detected on mungbean and blackgram,
and describes tle various pre- and post-emergence damage caused by the
parasitic species. [THH]

Out of 16 cultures of Aspergillus flavus isolated from 78 mungbean seed and

aflatoxigenic. [EMSJ

Leachates obtained after 6, 12 and 18 hours of soaking seeds produced both
inhibitory and stimulatory effects on the spore germination of the seed
mycoflora. Leachates of both Vigna radiata and V. mungo retarded the spore
germination of Aspergillus flavus, Alternaria alternata, Ascotricha chartarum,
