Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not
naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress
protectant in plants. While GB can increase tolerance of tomato plants to salt and
drought stresses, its effect on chilling tolerance has not been examined. To evaluate
whether...
Solanum species differ in their degree of frost tolerance and cold acclimation
capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive,
incapable of cold acclimation, and have a maximum freezing tolerance of –3°C.
Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation
and –10ºC post-acclimation. Breeding attempts...
In poplar (Populus spp.) a 32-kilodalton bark storage protein (BSP) accumulates
during the fall and winter, and is thought to be a major storage form of overwintering
nitrogen. BSP is induced by short-day (SD) photoperiod, and under natural conditions
BSP accumulation coincides with the induction of dormancy. Because BSP accumulates...
The appropriate use of disaggregated economic data not only improves the accuracy and robustness of economic analyses, but also extends the existing economic models to address new aspects of the issue. This dissertation consists of three essays: two essays use disaggregated economic-engineering data to address spatial heterogeneity in economic losses...
The ongoing climate change has impacted the lives and livelihoods of people. A climate-related disaster acts as an exogenous shock to the economy that can have lingering effects over a larger region even if all the locations are not directly affected. Climate-related disasters do not follow the administrative boundaries. So,...
