Evaluates how drought and phosphorus supply affect maize growth, revealing key genotypic differences in tolerance.

This research aims to understand how drought and phosphorus stress affect the growth of two maize inbred lines with differing tolerance levels.
Conducted a pot experiment using a randomized complete block design.
Evaluated two maize inbred lines under different phosphorus and water levels.
Measured biomass accumulation, leaf development, root morphology, and phosphorus content.
Drought significantly reduced shoot, leaf, and root weights, and leaf area in Line129 under low phosphorus.
Line1 maintained a higher root:shoot ratio compared to Line129 across conditions.
Low phosphorus supply increased the root:shoot ratio, particularly in Line129.

Ge et al. (2026) studied this question.
