“…Recent studies for increasing tolerance to environmental stresses, through metabolic engineering of 482 (Waterman and Mole, 1994). These compounds have been implicated to stress resistance against biotic and abiotic factors (Bergmann et al, 1994). TP compounds are a large group of secondary metabolites, which can play a role in virtually any interaction a plant can have with its environment (Waterman and Mole, 1994).…”

The salinity of soil is among the most important abiotic stresses which limit agricultural productivity worldwide. The effects of salinity on growth, nutrient partitioning, chlorophyll, leaf relative water content, osmolytes accumulation and antioxidant compounds of pepper (Capsicum annuum L.) cultivars ('Granada', 'Goliath' and 'Nobili'), widely used in Cameroon, were investigated. Plants were subjected to four levels of NaCl (0, 50, 100 and 200 mM) at early seedling growth stage of plant development. Application of NaCl treatment led to a significant increase in total soluble sugars, proline, soluble proteins, total free amino acids content, peroxydase and superoxide dismutase activity and total phenolic content in salt-tolerant 'Granada' and 'Nobili' compared to salt-sensitive 'Goliath' and untreated plants, on the contrary, decreased in root dry weight, shoot dry weight, number of leaves, shoot length, stem diameter, total leaf area, chlorophyll and leaf relative water content in 'Goliath' at low salinity level. Flavonoid content, K, Ca and Mg concentrations were significantly reduced with increasing salinity in all cultivars. The highest Na concentrations were detected in the leaves while the lowest were recorded in the roots of 'Goliath' at high salinity level. The salt sensitivity of 'Goliath' seems to be increased osmotic adjustment through the strongly accumulation of Na in leaves while the salt tolerance of 'Granada' was related to its induce of antioxidative enzyme system more efficiently, resulting in higher osmolytes accumulation under salinity. 'Granada' was more tolerant and stable in physiological and biochemical traits suggesting that it could be grown in salt-affected soils.

“…It was improved by addition of fertilizer N, P and K, or rotation of barley with Vicia sativa (Andersen et al 1992a;Harris 1994) and shown to decrease in Fedeficient plants (Sharma et al 1994). Spraying of acetylsalicylic acid in aqueous solution on drought-stressed barley plants increased yield and WUE (Bergmann et al 1994). Intercropping of Pisum sativum, Vicia faba or Festuca rubra with barley resulted in greater WUE; this was attributed to differences in canopy structure and plant biomass production (Izaurralde et al1994).…”

Physiology describes the operation of a plant at the biochemical, cell, tissue, organ and whole plant levels, recognizing that all of these are under the control of the plant genome. In the case of crop plants we are interested in how the combined operation of all plant's functions leads to the production of the harvestable component which, in cereal crops, is generally grain. Broadly speaking, the most important of the physiological activities in a crop plant with regard to yield are dry matter production, nutrient uptake, plant component partitioning and the processes of development (especially grain filling and the other aspects of yield component development). The developmental processes occur sequentially in time and involve progressive shifts in physiology. As barley (Hordeum vulgare L.) is a feed grain and a major source of malting grain for beer and spirits, aspects of physiology that affect the amount of grain produced and its quality (the amount of energy and protein) are of special interest.

“…These compounds can be classified into soluble compounds such as phenolic acids, phenylpropanoids, flavonoids and quinones (Rispail et al 2005) and non-soluble compounds such as condensed tannins, lignins and cell-wall bound hydroxycinnamic acids. In addition, Phenolic compounds have been implicated to stress resistance against biotic and abiotic factors (Bergmann et al 1994;Waterman & Mole1994) and to play an important role in scavenging the free radicals (Mohamed & Aly 2008). The antioxidative property of phenolic compounds streams from their high reactivity as hydrogen or electron donors, and from the ability of the polyphenol-derived radical to stabilize and to delocalize the unpaired electron (Huang et al 2005).…”

Salt stress is more and more becoming a serious problem in the world especially if we consider its damaging effect on the plant growth and yield. The cultivation of medicinal plants, such as Aloe vera, might be an alternative for the saline water use and salt-affected soils occupation. Aloe vera, commonly known as aloe, is one of the primary medicinal plants with multipurpose applications going from pharmaceutical to cosmetic aspects with a promising economic return. Aloe plants were cultivated and irrigated, for 14 months, with drinking water (C0) and with two levels of salt (C1 and C2). Changes in growth, hydrogen peroxide (H 2 O 2 ), lipid peroxidation and phenolic compounds were examined in leaves at harvest. Depressive effects of salt irrigation on the plant growth parameters and a perturbation in inorganic ion contents were found especially with a high level of salt in the irrigation water. The intracellular oxidative stress was evaluated with the H 2 O 2 production. Our results showed that the H 2 O 2 content increased with the accumulation of the toxic ion (Na) in the leaf tissues. In addition, lipid peroxidation, measured by the malondialdehyde (MDA) level, increased as well with salt augmentation in the irrigation water. In response to salt stress, Aloe leaves showed a significant increase in the levels of phenolic compounds too. These results suggest that Aloe can be planted in soils affected by salinity and irrigated with salt water at least at a moderate concentration used in the present study.
