Fig. 2From: Characterization of contrasting rice (Oryza sativa L.) genotypes reveals the Pi-efficient schema for phosphate starvation toleranceRoot morphology of the contrasting rice genotypes (Pusa-44, stress-sensitive; NIL-23, stress-tolerant) under Pi-starvation stress compared with that of the Pup1 QTL donor (Kasalath). A Comparision of the root bulkiness, B comparision of thickness and spread of the roots, C comparision of the secondary and tertiary roots. Roots of 45-day-old plants grown under control (16Â ppm inorganic phosphorus) or treatment (0Â ppm Pi) were used for comparative assessmentBack to article page
