Integrating physiological criteria associated with yield potential
1996
Araus, J.L.
The present study provides insights into physiological criteria that may be useful in breeding for yield potential in wheat and other cereals. Some of the most promising screening criteria currently emerging are 'integrative' in nature, that is, they can integrate the functioning of the crop in time (i.e., during the plant cycle) or level of organization (e.g. whole plant, canopy). They are based, for example, on the analysis, in different plant parts, of the stable carbon and nitrogen composition or the ash content. Also worth mentioning is the use of remote sensing approaches and, among them, indexes based on the spectral reflectance signature of the canopy or the utilization of NIRS technique as a surrogate for carbon isotope discrimination or ash content.
