Seed samples with highest (CB10), lowest (CB8), moderate fungal frequency (CB3) and randomly selected seeds from all varieties (CB1-14) were used. A total of 14 species of fungi, namely Aspergillus flavus Link, A. fumigatus Fresenius, A. niger Van Tiegh, Curvularia lunata (Wakker) Boedijn, Colletotrichum gloeosporioides Penz & Sacc, Fusarium nivale (Fr.)

Vuill., Syncephalastrum racemosum Cohn and Trichoderma viride Pers. were found to be associated with seed parts of different varieties of cotton. The maximum ten species of fungi were isolated from seed coat. The most prevalent fungus was Rhizopus stolonifer which was found in all the parts of all the varieties of cotton seeds examined. Out of the 14 isolated fungi, Aspergillus flavus, A. fumigatus, A. niger, C. lunata, C. gloeosporioides, F. nivale, F. oxysporum, F. fujikuroi, Penicillium aculeatum, R. solani, R. stolonifer, S. racemosum and T. viride were found to be external and Aspergillus flavus, A. fumigatus, A. niger, C. lunata, F. nivale, Penicillium citrinum and R. stolonifer were internal seed borne fungi. Aspergillus flavus, A. fumigatus, A. niger, C. lunata, F. nivale and R. stolonifer were isolated as both external and internal seed borne fungi. Dhaka Univ. J. Biol. Sci. 29(2): 237-244, 2020 (July)

Two types of symptoms, blight and anthracnose, were recorded on two species of Gerbera viz. Gerbera aurantiaca L. and Gerbera viridifolia L. The most common fungal species isolated from Gerbera spp. were Alternaria citrii, A. tennuisssima, Aspergillus flavus, A. fumigatus, A. niger, A. terreus, Bipolaris hawaiiensis, Chaetomella raphigera, Cladosporium cladosporoides, Colletotrichum capsici, C. coffeanum, C. dematium, C. gleosporioides, C. lindemuthianum, C. musae, C. orbiculare, Colletorichum sp.1, Colletotrichum sp.2, Colletotrichum sp.3, Colletotrichum sp.4, Curvularia clavata, C. lunata, Fusarium nivale, F. semitectum, Phomopsis sp., Penicillium sp., Pestalotia sp., Rhizopus stolonifer, Trichoderma viride, one cleistothecial ascomycetes and one sterile fungus. The frequency percentage of association of Colletotrichum spp. with Gerbera spp. was higher than any other fungi. Bipolaris hawaiiensis is a new record for Bangladesh. Among the isolated fungi Alternaria citrii, A. tennuissima, Colletotrichum capcisi, C. dematium, C. coffeanum and Curvularia clavata were found to be pathogenic to Gerbera plant.

Lucet & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. were found to be associated with the seeds of 14 varieties (CB 1- CB 14) of cotton. Out of these 24 fungal species, nine were found to be pathogenic to cotton. They were Aspergillus flavus, A. niger (Type 1), Aspergillus sp. 1, Colletotrichum gloeosporioides, Curvularia lunata, Fusarium nivale, F. moniliforme, Mucor sp. and Rhizoctonia solani. These pathogenic fungi had remarkable effect on seed germination, vigor index, root-shoot length and mortality of cotton seedlings. The germination percentage of control seeds was 88 but because of the presence of pathogenic fungi the rate showed considerable reduction in all the varieties and it varied from 20 to 82%. Among the nine fungal isolates Rhizoctonia solani showed maximum reduction in seed germination. Aspergillus flavus, Colletotrichum gloeosporioides and Fusarium moniliforme also caused near about 50% reduction in seed germination. Mortality percentage of control seedling were also less (6) whereas, in inoculated seeds it was higher and varied from 7 - 23%. Root- shoot ratio of control seedlings was high but less in inoculated seedlings. The vigor index of control plant was high (1548.8) but less in inoculated plants. The lowest vigor index was noticed for Rhizoctonia solani (202.0) and highest for Aspergillus sp. 1(1213.6). Results indicated that Curvularia lunata and Rhizoctonia solani showed a greater impact in reduction of cotton seed germination and vigor index. Dhaka Univ. J. Biol.

Present paper deals with the occurrence and diversity of fungi on storage cotton (Gossypium hirsutum L.) seeds. 24 species of the fungi were found associated with the seeds of 14 varieties of cotton after 10 months of storage. The isolated fungi were Aspergillus flavus Link, A. fumigatus Fresenius, A. niger (Type 1 and Type 2) Van Tiegh, A. ochraceus K. Wilhelm, A. nidulans Eidam, Aspergillus sp.1, Aspergillus sp.2, Aspergillus sp.3, Curvularia lunata (Wakker) Boedijn, Colletotrichum gloeosporioides Penz & Sacc, C. gossypii Southw., Chaetomium globosum Kunze., Fusarium nivale (Fr.)

Vuill., Rhizomucor Lucet & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. The association of fungi with cotton seeds was recorded within two months of harvest, after 6 and 10 months of storage. The association of fungi varied with duration of storage periods. Aspergillus flavus, A. fumigatus, A. niger, Chaetomium globosum, Penicillium sp.1 and Rhizopus stolonifer were found in all the examined varieties. These were the most predominant fungi in terms of prevalence with the increase of storage periods. The fungal association with the seeds of cotton also affected the germination, seedling mortality, height and vigor. The total association of fungi in cotton seeds was the highest in cotton variety CB10 (204) and the lowest in CB8 (71). On the other hand, the total fungal association of Rhizopus stolonifer was the highest (337) and Colletotrichum gossypii was the lowest (1). J. Biodivers. Conserv. Bioresour.

A total of nine species of fungi were found to be associated with seeds of nine varieties of chickpea. The isolated fungi were Alternaria alternata, Aspergillus flavus, A. niger, A. fumigatus, A. nidulans, Curvularia lunata, Penicillium sp., Rhizopus stolonifer and Trichoderma viride. Association of fungi with chickpea seeds was recorded three times, within a week after harvest, after two and five months of storage. The fungal association varied with duration of storage period. Species of Aspergillus, Penicillium and Rhizopus become predominating fungi with increase of the storage period. The fungal association with seeds of chickpea also affects germination, seedling mortality and seedling height. Germination of BARI chola 6 and 7 were completely inhibited due to prevalence of Rhizopus stolonifer in the seeds examined within seven days of harvest. The total fungal infection in chickpea seeds was highest in BARI chola 8 (168) and lowest in BARI chola 1 (65).Journal of Bangladesh Academy of Sciences, Vol. 40, No. 1, 37-44, 2016

Aims: The study aims to identifying the microorganisms associated with post-harvest rot of frafra potatoes in Bongo-soe, Upper east region of Ghana. Place and Duration of Study: Department of Horticulture and the Pathology laboratory of the Faculty of Agriculture, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. The Solenostemon rotundifolius tubers were stored at the Horticulture Department laboratory whiles rot identification was carried out at the Pathology laboratory of the Faculty of Agriculture. The Tubers were stored from 2nd November, 2012 to 22nd March 2013. Methodology: Four hundred (400) tubers of black cultivar and four hundred (400) tubers of a brown cultivar of Solenostemon rotundifolius tubers showing visible signs of rot during the storage were collected. Pieces of diseased tissues from the margin of the necrotic collected and immersed in 10% commercial bleach solution for sterilisation, for one minute. These were then blotted dry and plated on Potato Dextrose Agar PDA. The plates were sealed with a cellotape until growth occurred. Results: The microorganisms identified to be responsible for causing rot in Solenostemon rotundifolius tubers were six in number. Colletotrichum gloeosporioides was identified to be responsible for 30.76% of rots observed, followed by Aspergillus niger, 23.07%, Curvularia lunata, 19.23%, Aspergillus flavus, 11.54%, Trichoderma sp and Penicillium sp both recorded 7.70% of rots observed. The percentage incidence of Aspergillus niger (15.38%), Curvularia lunata (11.54%) and Aspergillus flavus (7.69%) was higher in the black cultivar as compared with the brown cultivar which had percentage incidence of 7.69%, 7.69% and 3.85% respectively. Also, the percentage incidence of Colletotrichum gloeosporioides (15.38%) and Penicillium sp (3.85%) was the same in both the black and brown cultivars of Solenostemon rotundifolius tubers used in this study. Conclusion: The activities of the damaging microorganisms can be reduced by controlling mechanical injury during harvesting, transportation and storage of Solenostemon rotundifolius tubers should be prevented or reduced because they pave the way for tuber infection by the rot causing microorganisms.
