tailieunhanh - Seed morpho – Metric, physiological and biochemical characterization on carrot (Daucus carota L.) genotypes

Laboratory experiments on seed morpho-metric, physiological and biochemical tests were carried out at Department of Seed Science and Technology, College of Agriculture, University of Agricultural Sciences, Raichur during 2017-18. In the present study 13 accessions were used viz., IC623126, IC-623129, IC-623127, IC-614611, IC-614612, IC-623128, IC-616039, IC-623130, IC591033, IC-405214, IC-565022, IC-512325 (procured from NBPGR, New Delhi) and a Local variety (Belumgi, Kalburgi Dist.) to assess the seed morpho-metric characters viz., seed colour, spines on seed (by using Leica microscope), seed length, seed breadth, length/breadth ratio (by using Biovis image analyzer), test weight; physiological tests viz., germination, root length, shoot length, seedling length, seedling dry weight, seedling vigour index I and II, biochemical tests viz., dehydrogenase enzyme activity and alpha amylase activity, using Complete Randomized Design in four replication. The results revealed that, the genotypes showed varied response to biochemical tests, physiological parameters and seed morpho-metric characters. Out of 13 genotypes, in 2 genotypes the seed colour was pale brown and in 11 genotypes the seed colour was field drab colour. Spines were present on 9 genotypes and absent in 3 genotypes. The seed length was highest () in IC-405214 and lowest () in IC-616039. | Seed morpho – Metric, physiological and biochemical characterization on carrot (Daucus carota L.) genotypes
