Unveiling the role of root functional traits in enhancing nitrogen use efficiency in wheat under nitrogen deficiency.

ABSTRACT:

Background

Genetic variation in plant functional traits has been recognized as a potential avenue for enhancing nitrogen use efficiency (NUE) in wheat, which is a cost-effective strategy for reducing environmental burden of excessive N fertilizer application. In this study, a total of 126 diverse wheat genotypes originating from 16 countries were cultivated in pots supplied with a low N level at 10 mg kg^- 1 to explore the functional traits determining NUE and their responses to N limitation.

Results

Under low N condition, significant genetic variations were observed in root morphological traits, photosynthesis capability and NUE among the wheat genotypes. The ranges of NUE and physiological NUE across 126 genotypes were 0.39-1.41 g mg^- 1 and 0.39-1.26 g
