“…Although some reports showed that the responses of oil palm are related to water stress (Smith, 1988;Caliman, 1992;Gawankar et al, 2003;Kallarackal et al, 2004;Henson et al, 2005;Mohd Roslan Noor, 2006;Legros et al, 2009;Omorefe and Bonaventure, 2010;Cha-um et al, 2010), or the effects of nutrient on plant growth, physiological variance and yield of oil palm (Ng, 1979;Van Kraalingena et al, 1989;Remison et al, 2000;Bah and Rahman, 2004;Taryo-Adiwigandaa et al, 2006;Anuar et al, 2008;Tan et al, 2010), to our knowledge little is known about the effects of water and nutrient stress on this plant. Therefore, there is a pressing need to know in more detail how oil palm responds and adapts to such conditions.…”

The research was conducted to detect changes in growth, physiology and nutrient concentration in response to two watering regimes (well-watered and water-stress conditions) and to two nutrient regimes (with or without fertilization) of oil palm. Under stress conditions, changes in plant growth, dry matter allocation, relative water content, leaf relative conductivity, leaf N, P and K concentration are usually observed. These characteristics and related parameters were determined and the experiment results are listed as follows: (1) fertilization promoted the growth of oil palm under well-watered conditions, while under water stress conditions its effects on growth was negative. The ratio of root/shoot was increased under water stress condition; (2) relative water content and chlorophyll a/b content were gradually decreased while leaf relative conductivity was increased quickly under water and nutrient stress conditions during the experiment. It is obvious that water stress had a greater influence than nutrient stress on these parameters; (3) water and nutrient stress decreased leaf nitrogen and phosphorus concentration but increased potassium concentration; the combination of water and nutrient stress made significant effects on nitrogen and phosphorus concentration, but no significant effects on potassium concentration. Moreover, deficiency of both water and nutrients in combination had the greatest impact on changes in these traits of oil palm.

“…Thus, in terms of water deficit, the photosynthetic rate and transpiration decreased considerably, as pointed out by several authors (Smith, 1989;Martínez and Moreno, 1992;Prieto et al, 2004;Romero et al, 2007;Moreno, 2009;Cha et al, 2010), due mainly to stomatal closure that inhibits the diffusion of CO 2 into the leaf and decreases its level (Ramachandra et al, 2004;Haniff, 2006). The response of OxG hybrids was a differential and was dependent upon the soil moisture regime (Figure 3).…”

“…Therefore, the detection of differences in oil palm behavior under drought conditions, according to their genetic origin and type of cross, partially independent of their production potential, means that genetics is the best alternative to RESEARCH ARTICLE identify high-performing crosses and parents (Cornaire et al, 1994). Drought tolerance does not depend on a single physiological trait, but on the relative contribution of several tolerance mechanisms that can operate at different stages of a plant development (Jaleel et al, 2009), such as stomatal conductance during the dry season, photosynthetic potential, root system, osmotic adjustment, and reserves of assimilates (Smith, 1989;Villalobos et al, 1990;Martínez and Moreno, 1992;Cayón, 1998;Nieto et al, 2009). …”

Modelling Visible Foliar Injury Effects on Canopy Photosynthesis and Potential Crop Yield Losses Resulting from Fluoride Exposure

Crop production models are highly developed to account for different nitrogen, light, temperature and water availability conditions and, in some species, disease or air pollutant effects. There is very limited knowledge on responses of many tropical crops, such as oil palm (Elaeis guineensis), to air pollutants although predictions of these effects are essential for industrial planning in several countries. In the absence of limitations due to water supply, the effects of leaf area loss due to necrosis and chlorosis are much more important to canopy photosynthesis than are changes in the physiological attributes that influence the efficiency of light use. Therefore, potential losses of crop production due to air pollutants such as fluoride can be inferred usefully from the extent of visible injury to foliage that may be associated with different levels of pollutant exposure.
