Figure 1. Growth behaviour of Dular and PB1 under P deficiency.

(a) Plant phenotype of 15-days-old hydroponically grown seedlings under 1, 100 and 320 μM concentrations of Pi (NaH₂PO₄). Scale bar = 8.5 cm. (b) average fresh weight, (c) average dry weight of Dular and PB1 under different P regimes. (d) Root hair length of 5-days-old MS grown Dular and PB1 with 0, 100 and 320 μM concentrations of Pi (KH₂PO₄). (e) Total P content of hydroponically grown seedlings under 1, 100 and 320 μM concentrations of Pi (NaH₂PO₄). p values determined by student t-test using PB1 as control for each condition have been represented as ‘***’=p ≤ 0.001, ‘**’ =p ≤ 0.01, ‘*’=p ≤ 0.05 and ‘ns’ = not significant.
