Effect of seed mycoflora on seed germination and seedling vigour of cowpea cultivars
Author(s): KI Vasava, VR Gohel and KD Vaghela
Abstract: The seed germination, seedlings length and Seedling Vigour Index (SVI) of cowpea cultivars was drastically reduced by all the seed mycoflora except Macrophomina phaseolina and Alternaria alternata. Fusarium oxysporum showed maximum detrimental effects on seed germination, seedling length and SVI in all cultivars. Aspergillus terreus and Macrophomina phaseolina showed relatively less inhibitory effect on seed germination in cultivar GDVC 1 and seedlings length of GC 3 and GDVC 1 as compared to other cultivars. Rhizopus sp., Fusarium oxysporum, Aspergillus terreus, Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Alternaria alternata and Macrophomina phaseolina showed seed germination, seedlings length and SVI between 27.50 to 85.75 per cent, 6.00 to 7.92 cm and 185.62 to 671.22, respectively in all the cultivars. Discoloration on cowpea seedling increased by seed mycoflora infection in all cultivars. The highest per cent discoloration intensity (PDI) was recorded in Fusarium oxysporum treatment. On the basis of per cent seed germination of the cultivar GDVC 1 and AVCP 1, seedling length of the cultivar GC 3 and GC 4, SVI of the cultivars GDVC 1 and AVCP 1 and PDI of the cultivars GC 3 and GDVC 1 appeared to be least tolerant to seed mycoflora.
