“…But Stroup et al (2003) have suggested that nutrient determines the plant growth even more than water availability does. The nutrient availability has been found to alter allocation patterns: the values of the parameter root: shoot, decreased in the conditions with fertilization when compared to conditions without fertilization, despite the same watering regimes.…”

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.

“…Moreover, nitrogen deficiency suppresses growth rate and leaf photosynthesis (Zhao et al, 2003), and N pulse increases photosynthetic rates and thus growth (Warren et al, 2004). Stroup et al (2003) have suggested that nitrogen determines the growth potential of cultivars even more than water availability does. But Castell and Terradas (1994) concluded that water is a more limiting factor than nutrients in the case of A. unedo.…”

“…Cellular pathways that improve forage quality may be different than those needed for biomass (Casler and Vogel, 1999;Mitchell et al, 2001;Lemus et al, 2002;Stroup et al, 2003). Thus, it is critical to obtain cellular and molecular information on switchgrass to more fully guide existing and future breeding programs.…”

Sarath, Gautam; Baird, Lisa M.; Vogel, Kenneth P.; and Mitchell, Robert B., "Internode structure and cell wall composition in maturing tillers of switchgrass (Panicum virgatum. L)" (2007 Abstract This work examined cell composition gradients in maturing tillers o f switchgrass (Panicum virgatuln L.) with the aim o f developing baseline information on this important forage and biomass crop. Flowering tillers were collected from plants raised from seeds in a greenhouse and field, harvested at soil level and separated into internodes beginning with the node subtending the peduncle. Internodes were analyzed using microscopy, by fiber digestion, high-performance liquid chromatography and by gas chromatography-mass spectrometry to obtain anatomical and compositional data. Microscopy demonstrated the development and maturation o f cortical fibers which eventually became confluent with the fiber sheath surrounding vascular bundles in the lower internodes. Detergent fiber analysis indicated increasing cellulose and lignin contents and decreases in cell solubles
