Abstract:
... As the concentrations of essential vitamins and minerals and a number of other health‐promoting compounds are often low in stable crops, research is under way to understand and increase synthesis of phytochemicals in order to improve crop nutritional quality. The question addressed in this study is whether shoot genotypes or root genotypes with tolerant drought character are able to increase the f ...

Abstract:
... From May to October 2006 we applied two water treatments in an olive orchard in south Spain with 38-year-old ‘Manzanilla’ trees at 7x5 m spacing: a) rainfed, with rainfall as the only source of water supply; b) FAO, in which the trees were drip-irrigated daily from May to September, to replace the crop water needs. The aim of this work was to evaluate the influence of the water treatments on both ...

Abstract:
... Drought is considered to be the main environmental factor limiting photosynthesis (AN) and, consequently, plant growth and yield worldwide. During photosynthesis, the pathway of CO2 from the atmosphere to the site of carboxylation in the chloroplast stroma has two main components: stomatal (gs) and mesophyll (gm) conductances. Both are finite and dynamic, responding to many abiotic factors, theref ...
