Book Description
​Global climate change is expected to produce increased carbon dioxide levels in the atmosphere, higher temperatures, aberrant precipitation patterns and a host of other climatic changes that would affect all life on this planet. This review article addresses the impact of climate change on fruit trees and the response of the trees to a changing environment. The response of fruit trees to increasing carbon dioxide levels, phenological changes occurring in the trees themselves due to increased temperature and the lower chilling hours especially in the temperate regions, ecophysiological adaptations of the trees to the changing climate, impact of aberrant precipitation, etc. are reviewed. There is very little data on the impact of rising CO2 levels on fruit tree performance or productivity including the temperate region. Based on a large number of observations on the phenology, there is reason to believe that the flowering and fruiting of most species have advanced by quite a few days, but with variations in different crops and on different continents. The chilling hours have also grown shorter in many regions, causing considerable reductions in yield for several species. In the tropics, there is very little work on fruit trees; however, the available data show that precipitation is a major factor regulating their phenology and yield. The ecophysiological adaptations vary from species to species, and there is a need to develop phenological models in order to estimate the impact of climate change on plant development in different regions of the world. More research is also called for to develop adaptation strategies to circumvent the negative impacts of climate change.

Book Description
ABSTRACT: The overall objective of the application of partial root zone drying (PRD) was to evaluate whether this mild drought stress could improve whole plant water use efficiency (WUE) and leaf WUE in potted citrus. Knowledge of how citrus trees cope with PRD can be the basis for successfully applying deficit irrigation. Therefore, the feasibility, risks or potential benefits of PRD with saline water or with good quality water were evaluated to determine the scope for water savings, changes in plant water relations, growth, WUE and nutritional responses. Results demonstrated that PRD with saline and with good quality water from the spring season to early summer, saved water and restricted plant growth while leaf nitrogen (N) was not limiting regardless of treatments. Roots in wet soil of PRD-treated plants did not enable PRD plants to maintain water status relative to well-watered (WW) plants. Whole plant WUE and root abscisic acid (ABA) at the end of the study were similar across treatments. Higher leaf ABA in PRD with saline water may have partly contributed to the lower stomatal conductance (g[subscript]s), transpiration (TR), and water consumption compared with WW plants. Rates of net CO2 assimilation (A[subscript]CO2) were reduced more than those of leaf TR in PRD-treated plants resulting in decreased leaf WUE. Therefore, PRD-treated plants resulted in water savings but drought stress reduced leaf function.
