“…It plays an important role in plant growth as it is involved in cell division and expansion as well as other different physiological processes (De Gara et al 2003). In our study, an increase in ascorbic acid content in spinach plants exposed to drought was similar to what has earlier been observed in maize showing a marked increase in the levels of ascorbic acid particularly under high intensity of drought (Dolatabadian et al 2010). Phenolics are also non-enzymatic compounds which are known to play an essential role in transporting their hydrogen atoms to reduce the ROS generated under stress (Frary et al 2010).…”

It is known that leafy vegetables including spinach (Spinacea oleracea L.) contain relatively high amount of water, therefore, their water requirement during the life cycle is comparatively more than the other vegetables. In addition, there is an association between osmoprotection and antioxidants with reference to drought stress tolerance. Keeping in mind these facts, the present study was conducted to assess the changes in plant growth, osmoprotectants, chlorophyll pigments and activities/levels of antioxidative system in spinach (Spinacea oleracea L.) grown under varying water deficit regimes with 40%, 60%, 80% and 100% field capacity (FC). Imposition of varying water regimes significantly decreased shoot and root fresh and dry weights, shoot plus root lengths, and chlorophyll b contents of spinach plants. Increase in proline, glycinebetaine (GB), total phenolics, ascorbic acid and malondialdehyde (MDA) contents as well as the activities of antioxidant enzymes including superoxide dismutase, peroxidase and catalase were observed in the spinach plants particularly at 40% FC. The most effective level of water stress for elevating the proline, GB and antioxidant levels/ activities was observed at 40% FC followed by 60% FC. Hence, the results of this study suggested that upregulation of antioxidants and osmoprotectants is positively associated with the drought tolerance of spinach which depends on the severity of water stress level. These results can be used to narrow the gap between selection of plant species and requirement of irrigated water for the crops grown on dry land areas. ABSTRAKAdalah diketahui bahawa sayur-sayuran berdaun termasuk bayam (Spinacea oleracea L.) mengandungi jumlah air yang agak tinggi, oleh itu, mereka memerlukan lebih air sepanjang kitaran hidup berbanding sayur-sayuran lain. Di samping itu, terdapat hubungan antara osmoperlindungan dan antioksidan berkaitan toleransi tekanan kemarau. Dengan mengambil kira fakta tersebut, kajian ini dijalankan untuk menilai perubahan dalam pertumbuhan tanaman, osmoperlindungan, pigmen klorofil serta aktiviti/tahap sistem antioksidatif pada bayam (Spinacea oleracea L.) yang ditanam di bawah rejim defisit air berbeza dengan 40%, 60%, 80% dan 100% kapasiti lapangan (FC). Pengenaan rejim air yang berbeza dengan ketara mengurangkan berat segar dan kering pucuk dan akar, panjang pucuk dan akar serta kandungan klorofil b pada pokok bayam. Pertambahan kandungan prolin, glisinbetain (GB), jumlah fenolik, asid askorbik dan malondialdehid (MDA) serta aktiviti enzim antioksida termasuk superoksida dismutase, peroksidase dan katalase telah diperhatikan pada tanaman bayam terutamanya pada 40% FC. Tahap tekanan air paling berkesan untuk meningkatkan tahap/aktiviti proline, GB dan antioksidan diperhatikan pada 40% FC diikuti 60% FC. Oleh itu, keputusan kajian ini mencadangkan pengawalaturan atas antioksidan dan osmoperlindungan dikaitkan secara positif dengan toleransi kemarau oleh bayam yang bergantung pada keterukan aras tekanan air. Keputusan ini boleh digunakan unt...

A N EXPERIMENT was conducted to assess the responses of Carum carvi to lead stress and using ascorbic acid and α tochopherol as antioxidants. In this experiment, plants were grown in the nutrient medium with different levels of lead (0, 50, 100,200,500 and 1000 mM) in the form of lead nitrate Pb(NO 3 ) 2 .Ascorbic acid or α tochopherol level (each 50 ppm) was used as seed presoaked for 8 h.The interactiveeffects were recorded on plant biomass, biosynthesis of photosynthetic pigments, proline, oil contents and flavonidsin Carum carvi plant. From our present results, itcouldbe concluded thatseed presoaked applications of ascorbic acid orα tocopherol could play a role to alleviate the harmful effect of lead stress on some metabolic and physiological processes of Carum carvi that reflected in, increasing fresh-dry matter of different organs, inducing a significant stimulatory effect of carotenoid contents, increasing oil, proline and flavonoid contents.

“…Three (200ppm) had significantly stimulatory effect on growth parameters of jojoba plants in term of plant height, number of branches, and leaves/plant and leaf area compared with the untreated plants, as this respect (2). Antioxidant is very effective in improving the plant biomass (16,17,27). Foliar-applied SA, AsA and proline were effective in improving the plant growth of both cucumber cultivars.…”

“…It is an essential cofactor for numerous metabolic enzymes including amino acid metabolism and antibiotic biosynthesis. Most interestingly, it has recently been found that the vitamin is a potent antioxidant with a particular ability to quench reactive oxygen species such as superoxide and singlet oxygen, (16). Proline, and its metabolism, is distinguished from other amino acids in several ways.…”

Two field experiments of jojoba plants were carried out in Almaghara Research and Production Station followed to Desert Research Center, Agriculture Ministry, North Sinai Governorate, Egypt, at 2016/2017 and 2017/2018, Respectively. Therefor to study the influence yield of five clones (S-L, S-610, S- 700, S-B and S-G) under foliar spray of salicylic acid, ascorbic acid and proline [(50:50:50(conc. 1); 100:100:100 (conc. 2) and 200:200:200 ppm (conic. 3)] on jojoba plants at four and fourteen years old from planting. The experiment was conducted as split plot design, were varieties order in the main plots and treatments in sub plots, uisg three replicates. esults showed that the foliar application of salicylic acid, ascorbic acid and proline led to increase of all growth characters, yield characters and some chemical contents in leaves and seeds on all of clones. Clones S-700 recoded the highest values for all traits studied followed by clones S-B, while, studied traits, clones S-L recorded the lowest values. Foliar spray application with salicylic acid, ascorbic acid and proline had the highest data with all clones with aged fourteen years compear aged four years. All characters increased with increase in salicylic acid, ascorbic acid and proline on varieties, especially clone S-700. Jojoba plants appearance response to plant nutrition.
