Rodríguez Delfin, A.Posadas, A.Quiróz, R.[Rendimiento y absorcion de algunos nutrimentos en plantas de camote cultivadas con estres hidrico y salino.]Rendimiento y absorcion de algunos nutrimentos en plantas de camote cultivadas con estres hidrico y salino.

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.Yactayo, W.Rens, L.R.Rolando, J.L.Palacios, S.Mendiburu, F. deMares, V.Barreda, CarolinaLoayza, H.Monneveux, P.Zotarelli, L.Khan, A.Quiróz, R.[Defining biological thresholds associated to plant water status for monitoring water restriction effects: Stomatal conductance and photosynthesis recovery as key indicators in potato.]Defining biological thresholds associated to plant water status for monitoring water restriction effects: Stomatal conductance and photosynthesis recovery as key indicators in potato.

Accurate determination of plant water status is mandatory to optimize irrigation scheduling and thus maximize yield. Infrared thermography (IRT) can be used as a proxy for detecting stomatal closure as a measure of plant water stress. In this study, an open-source software (Thermal Image Processo...

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?
Yactayo, W.Ramírez, D.Gutiérrez, R.Mares, V.Posadas, A.Quiróz, R.[Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency.]Effect of partial root-zone drying irrigation timing on potato tuber yield and water use efficiency.
Rodríguez Delfin, A.Posadas, A.León Velarde, C.Mares, V.Quiróz, R.[International Symposium on Soilless Culture and Hydroponics. Puebla (Mexico). 15-19 May 2011][Effect of salt and water stress on the proline and total chlorophyll content and nutrients uptake on two sweet potato cultivars grown on soilless culture.]Effect of salt and water stress on the proline and total chlorophyll content and nutrients uptake on two sweet potato cultivars grown on soilless culture.

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...


Rinza, J.Ramírez, D.García, J.Mendiburu, F. deYactayo, W.Barreda, CarolinaVelásquez, T.Mejia, A.Quiróz, R.[Infrared radiometry as a tool for early water deficit detection: insights into its use for establishing irrigation calendars for potatoes under humid conditions]Infrared radiometry as a tool for early water deficit detection: insights into its use for establishing irrigation calendars for potatoes under humid conditions
