Elimination of intrinsic variability in radicle length. (A) Seeds of rice genotype MI48 were germinated in a Petri plate lined with wet filter paper at 28°C for 4 days in dark. (B) Radicle lengths of germinated seedlings were measured by ImageJ program and categorized into different size ranges of 0.5 cm each. Histogram represents per cent seedlings in different size ranges. (C) About 30–40% seedlings falling in the size range of 2.0–3.0 cm were selected and transferred to hydroponic set up for temporal treatment under P+ and P- conditions.
