The plants were grown for 3 weeks under both well-watered and water-deficit conditions in long tubes to assess root length. We hypothesized that plants with deeper roots would exhibit higher productivity under drought conditions.application/pdfOpen Accessdrought stressfeed grassesroot lengthplant physiologyfisiología vegetalestres de sequialongitud de las raícesgramínea forrajerawater uptakeReport
