Lost in aggregation? On the importance of local food price data for food poverty estimates

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

INFLUENCE OF CHEMICAL FERTILIZATION ON STRAWBERRY FRUIT PRODUCTION

open access: yes, 2014
The nutritional control of strawberry is very difficult, because a large number of factors influence the absorption and availability of nutrients through mechanisms that are not fully understood.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

VALIDATED PROTOCOLS FOR MICROPROPAGATION OF SOME FRUIT SPECIES TO PRODUCE PRE-BASIC PLANT MATERIAL

open access: yes, 2012
Obtaining virus free fruit planting material, conservation and utilization for large scale production of certified fruit trees, was and is still an objective demand.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

CRITERIA FOR HARVESTING PLUMS AT THE OPTIMUM MATURITY FOR ROMANIAN VARIETIES OF THE FRESH FRUIT MARKET

open access: yes, 2012
Plum breeders and growers from Romania want to improve status of the plums for fresh consumption. Plum fruit quality depends on physical and chemical properties (shape, size, skin colour, bloom, taste and flavor, fruit soluble solids content and acidity,

Long‐term demography and spatial genetic structure reveal mechanisms of Sassafras albidum population persistence through clonality

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Vegetative regeneration is a key mechanism of woody plant persistence in forest ecosystems, and the coupled roles of basal sprouting and clonal growth in shaping long‐term population dynamics have been understudied. Basal sprouting replaces stems at fixed ramet locations, whereas clonal growth via root suckering produces spatially ...
