The definition of irrigation schedules depends on the understanding of the response of key plant traits to different water restriction characteristics with the aim to avoid physiological impairment. In this study, different timings (at tuber initiation and bulking) and intensities (four soil mois...

Ramírez, D.Rolando, J.L.Yactayo, W.Monneveux, P.Quiróz, R.[Is the discrimination against 13C in leaflets and tubers an appropiate trait to determine genotypic differences related to drought tolerance in potato?]Is the discrimination against 13C in leaflets and tubers an appropiate trait to determine genotypic differences related to drought tolerance in potato?

The search for plant traits associated with drought tolerance for genetic improvement is an important issue in breeding acceleration programs. However, plant traits expression depends on the drought scenario, thus the investigation of this dependence is crucial for drought tolerant related traits...

Low radiation is one of the most important factors which limits potential yield in potato. Under humid conditions, the dominance of diffuse radiation not only imposes challenges for radiation use efficiency in crops but also limits the water status surveillance through non-invasive methods like i...
