Abstract
The goal of this research was to estimate the tolerance of Aluminium in 34 Vigna mungo (L.) Hepper species under conditions of stress from aluminium. In a hydroponic test, 48hrs in different concentrations of Al (0, 25, 50 & 100μM) were assessed at all 34 black gram species. Variations in the Al-tolerance were analyzed based on the trait, mean root length taken over concentrations 0, 25, 50 & 100μM compared with absolute root length at control or 0μM
Based on the results, KVK Nayagarh-1(P25) KVK Puri-2(P19) were responded to be the best Al-tolerant genotypes as their mean root length over the concentrations 0,25,50,100μM as compared to root length to control had very less variation. Mean root length of P25 obtained was 6.49cm and its root length at control was 6.45cm and the mean root length of P19 was 6.54cm and its root length at control was 6.56cm whereas C4-OBG-31(P42) and CPRBAMGP-239(P38) were considered to be the most Al- sensitive black gram genotypes. P42 had mean root length of 6.08cm and its root length at control was 6.76cm. P38 had mean root length 5.33cm and its root length at control was 5.52cm which suggested significant variation.
Moreover, the effect of Al-accumulation on biochemical parameters were to be analyzed through the quantitative assessment of biochemical parameters such as chlorophyll estimation, protein estimation, overall carbohydrates estimation, estimation of MDA, estimation of Superoxide dismutase (SOD) and Atomic Absorption Spectrometry (AAS) material for aluminium uptake at roots for tolerant and sensitive genotype . However, with respect to objective viz., Assessment of biochemical and physiological changes of Vigna mungo under Al stress., the findings considered could not be obtained because the college abruptly closed down due to the Covid-19 pandemic on 15 March 2020 . If the situation had remained normal, the following results would have been achieved . The expected results are being mentioned in accordance with the available literature.
