Abstract

The effect of eight fungi filtrates (isolated from infected black point wheat grains) was carried out in 2020 on healthy seeds of okra (Abelmoschus esculentus) at Baba Farid College, Bathinda, Punjab. The total four concentrations i.e. 25, 50, 75 and 100% of twelve day old culture filtrates of Alternaria alternata, Aspergillus niger, Rhizopus spp., Helminthosporiums spp., Curvularia spp., Penicillium spp. and Fusarium spp. were used for present studies. These overnight pre-soaked seeds of okra were planted in pots under green house condition. Total three replications were used and each pot was having 12 seeds. Further the germination percentage of okra seeds was recorded. The result revealed that there was significantly reduction in percentages seed germination was observed as the concentration was increased. The maximum reduction of germination was recorded at 100% concentration in which Helminthosporium spp. (38.8±0.6) was showing maximum germination followed by Rhizopus spp. (30.

Conclusion

The present findings are significant are common in agricultural products like cereals, pulses, oil seeds, feeds (Fakhrunnisa et al., 2006). The current results are positively correlated with Narasimha Rao et al., (2006), reported reduction in the germination when treated with isolated filtrate of different pathogen. Consumption of wheat invaded by these myco-toxins indicates a potential risk for contamination and hazardous for human health (Gautam and Bhadauria, 2009; Masiello et al., 2020). However, consumers demand food and feed productions with a high qualitative standard to guarantee health of both human and other animals. Hence, this present finding is more significant and beneficial to the farmers as well as to the grower which should assist in managing risk and will encourage them for replacement of infected seeds to reduce the initial inoculums to minimise the amount of crop quality.
