Deciphering the influence of genotypic variability and ontogeny on selected parameters in chickpea microgreens for potential nutritional additive
摘要
Microgreens are fragile, young, plantlets having reservoirs of effective bioactive compounds that are vital nutrition dense source for human-health. The objective of the study undertaken was to compare morphological and biochemical parameters along with minerals in diverse chickpea genotypes (desi and kabuli) cultivated as microgreens from 7th day till 28th day. Calibrated results depicted a variability for studied parameters with gradual enhancement recorded for morphological attributes and pigment content with age. The total proteins content, antioxidant activity and ascorbic acid were highest at 7th day of cultivation, whereas, phenols were maximum on 14th day. Amongst minerals, sodium and calcium increased till 14th day, while potassium and zinc decreased. The age effect was negligible on the iron level. Kabuli genotypes performed better for growth parameters. While desi genotypes depicted superior performance for ascorbic acid and total phenolic content, kabuli genotypes showed higher ash and total protein content. Antioxidant activity remained at par in two types of genotypes. Sodium, potassium and calcium were more in kabuli, while, zinc was better in desi and iron remained unaffected by the genotypes. The findings showed that the parameters recorded were influenced by age of microgreens and genotypes used. Accordingly, chickpea genotypes Pusa-3062 and HK-4 (Antioxidant and Ascorbic acid) along with Pusa-4005 (Biomass and Phenols) can be used as a potential source of nutritionally rich microgreens till initial stage (i.e. 7th and 14th day) of growth.
