“…fertilization (nutrients not limiting) was greater than between fertilized and non-fertilized in the well-watered treatment (Yin et al, 2009). But Stroup et al (2003) have suggested that nutrient determines the plant growth even more than water availability does.…”

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.

“…The leaves have been dark-adapted for 30 min prior to the measurement and then they were used for chlorophyll fluorescence measurement using a modulated fluorometer (PAM 2100, Walz, Effeltrich, Germany) according to Yin et al (2009). The maximum quantum efficiency of PS II (Fv/Fm) was calculated as Fv/ Fm ¼ (Fm À Fo)/Fm (Rosenqvist and Van, 2003).…”

“…The soil water content was maintained as described by Yin et al [18]. Following changes in plant biomass, an empirical relationship between seedling fresh weight (Y, g) and seedling height (X, cm): Y ¼ 3.061 X -13.533, (R 2 ¼ 0.874, P < 0.001) was used to correct the amount of water in each pot.…”

“…When an excess of excitation energy induced by the limitation of CO 2 fixation in chloroplast is not dissipated, plants produce reactive oxygen species (ROS) [15], which can seriously impair the normal function of plants by lipid peroxidation, protein degradation, DNA nicking, and may even cause cell death [16]. Generally, the oxidative stress in plants is shown by accumulation of hydrogen peroxide (H 2 O 2 ) and an increase in malondialdehyde (MDA) content [17,18]. Accordingly, osmotic adjustment [19] and antioxidative protection [20] are used to counter the stress in plants.…”
