Fig 3. Regression plots between selected phenotypic traits for vegetative (green) and generative (blue) experiments (refer to S3 Fig for the summarized correlation matrix).

(a-f) present the correlation of plant dry mass, transpiration efficiency, harvest index, proline content, length of the main stem and the fraction of the main stem dry mass over the total plant dry mass on the yield; (g) plant dry mass and transpiration efficiency; (h-i) specific transpiration and dry weight of green leaves, and total plant dry weight respectively.
