Verbatim
e0“Solanum tuberosum L. varieties Agria and Rossi were cultivated”
e1“four foliar sprayings (at 8–10 day intervals) with CaCl2 (3 and 6 kg ha−1) or Ca(NO3)2 (2 and 4 kg ha−1) solutions were performed”
e2“both fertilizers increased Ca accumulation in tubers (mostly in the parenchyma tissues located in the center of the equatorial region)”

Other claims from this paper (10)
- Intervention effect The photosynthetic apparatus of potato was not affected by the sprays until the 3rd application.
- Intervention effect The photosynthetic apparatus of potato was somewhat affected after the 4th spray application, near the end of the crop cycle.
- Intervention effect Lower-dose CaCl2 seemed to improve the photochemical use of energy compared with the greater dose of Ca(NO3)2.
- Intervention effect Foliar calcium sprays did not modify potato tuber height and diameter.
- Observation Mean contents of P, K and Na in potato tubers show different accumulation patterns after calcium sprays.
- Observation Mean contents of Fe and Zn in potato tubers show different accumulation patterns after calcium sprays.
- Observation K, Fe and Mn accumulation prevails in the tuber epidermis, in contrast with the pattern of Ca.
- Observation Zn accumulation prevails in the tuber epidermis, in contrast with the pattern of Ca.
- Observation Ca accumulation in tubers shows a heterogeneous trend across the regions analyzed.
- Observation Calcium enrichment of tubers alters the accumulation of other nutrients.
