“…Proline would be a good source of energy and N for the plant under drought conditions. These results are agreement with the findings of Ahmed et al (1989), Namich (1997) and Ashraf and Foolad (2007). Natural materials significantly affected leaf total chlorophyll, phenols and proline content at 114 days after planting, in favor of spraying potassium citrate and significantly affected leaf carotenoids content, in favor of spraying salsalic acid.…”

Two field experiments were carried out at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate during the two successive seasons of 2015 and 2016. These experiments were conducted to find out the proper irrigation interval and the effect of natural material which reduce the negative effect of water stress as well as their interaction on leaf chemical composition, growth, flowering habit, earliness parameters, seed cotton yield and its components and fiber quality of the Egyptian cotton cultivar Giza 86. A split plot design with three replicates was used in both seasons, where the main plots were assigned to three irrigation intervals (15, 30 and 45 days) and the sub-plots contained natural materials (without, glycine betaine (600 ppm), potassium citrate (3g/l) and salsalic acid (200 ppm) The important results could be summarized as follows: Irrigating intervals gave significant effect on l e a f total chlorophyll, carotenoids, phenols and proline content at 114 days, when irrigated every 45 d a ys followed by irrigated every 30 and 15 day in a descending order. Irrigation every 15 days significantly increased plant height at harvest, number of fruiting branches/plant, number of flowers/plant, boll weight and decreased setting and earliness percentages in both seasons as compared with the other two irrigation intervals (every 30 and 45 days). However, the higher number of open bolls/plant and seed cotton yield / fed were obtained from plants which irrigated every 30 days. Irrigation intervals had insignificant effect on seed index and significant effect on lint % in both seasons. The highest value of lint % was resulted from irrigated plants every 45 days. Spraying with natural materials significantly affected leaf total chlorophyll, phenols and proline content, in favor of spraying potassium citrate and significantly affected leaf carotenoids content at, in favor of spraying salsalic acidSpraying with natural materials significantly affected boll weight and number of open bolls/plant in both seasons in favor of spraying glycine betaine and potassium citrate. Application of salsalic acid or glycine betaine gave significant increase in lint % and insignificant effect on seed index in both seasons. Spraying cotton plants with glycine betaine lead to a significant increase in seed cotton yield per fed. Untreated Plants caused a significant increase in plant height at harvest and number of fruiting branches/plant in both seasons as compared with the plants which received glycine betaine, potassium citrate and salsalic acid. Concerning the interaction between irrigation intervals and natural materials, there is a significant interaction effect with regard to l e a f total chlorophyll, carotenoids, phenols and proline contents, in favor of irrigated cotton plants every 45 days and spraying with potassium citrate for l e a f total chlorophyll, phenols and proline contents and in favor of irrigated cotton plants every 45 days and spraying with salsalic acid for l e a f carotenoids content. Irrigation every 30...

“…In our experiments, HPLC-separated basic polyphenol species, namely cinnamic acid derivatives (chlorogenic acid isomers) and flavonoids (mainly quercetin glycosides) were shown to decline in the drought-subjected plants ( Table 1). Decline of total leaf polyphenols has also been observed in pot trials with drought-experiencing cotton (Ahmed et al 1989). However, the fact that despite drought conditions the tolerant cv.…”

Compounds with reactive oxygen species (ROS)‐scavenging ability were studied. High‐performance liquid chromatography (HPLC) pattern of polyphenols, contents of proline and carotenoids, and antiradical (AR) capacity were determined. The malonyldialdehyde (MDA) level was also assessed. Tolerant and sensitive cotton genotypes were compared, grown in the Aegean region of Turkey at normal (field capacity) and limited (1/3 field capacity) water supply. Chlorogenic acid isomers and flavonoids were identified in HPLC pattern of polyphenols. At normal water supply, the tolerant genotype was distinguished by a higher content of all polyphenol types, higher proline, carotenoids and AR capacity and lower MDA level compared with the sensitive genotype. In plants subjected to water deficit, a decline of all polyphenol compounds, carotenoids and AR capacity was observed. However, this response was less pronounced in the tolerant than in the sensitive genotype, i.e. despite the stress conditions imposed, the tolerant plants maintained a more effective defence system. The data are corroborated by the weaker structural membrane damage in the drought‐exposed tolerant vs. sensitive genotype, according to the MDA test. Hence, diverse chemical types are involved in the non‐enzymatic ROS‐scavenging system of cotton plants and can be related to the drought tolerance of this important crop.

“…We observed that in the maize cultivars, total phenolics increased under drought stress. In contrast to these findings, drought stress reduced phenolics in cotton (Ahmad et al, 2008), canola (Shafiq et al, 2014), corn (Ali et al, 2011), while in contrast, an increase was observed in carrot (Razzaq et al, 2017) plants under stress conditions. In a previous study, an increase in AsA was observed in canola (Shafiq et al, 2014) plants that is analogous to what was observed in the present study under water deficit conditions.…”

Maize is an important cereal crop all-over the world and has been recently ranked at first among all cereal crops. However, growth of maize plants is negatively affected in arid and semi-arid areas of the globe due to scarcity of water, but genetically variable cultivars/lines differ considerably to respond to water limited conditions. To evaluate the response of some commercial cultivars of maize to water deficit conditions, a pot experiment was carried out. Eight maize cultivars (Sultan, Akbar, Pearl, MMRI, Maki Pak, Sahiwal 2002, Sadaf and Neelum) were subjected to varying [100%, 75% and 60% of field capacity (FC)] levels of water deficit conditions. Drought stress significantly decreased shoot fresh and dry weights, root fresh and dry weights and chlorophyll pigments (a and b) in all maize cultivars. However, free proline, glycinebetaine (GB), total phenolics, hydrogen peroxide (H2O2), malondialdehyde (MDA) contents, activities of enzymatic antioxidants (CAT, POD and SOD) and ascorbic acid (AsA) contents increased significantly under water deficit conditions. Of all maize cultivars, cv. Sadaf was superior in terms of plant growth, while, cv. Sultan proved to be inferior to the other cultivars examined in this study. It was concluded that osmoprotectants such as proline and GB can be used as stress tolerance indicators under drought stress conditions.
