“…6a and b). This result is in agreement with the work of Ali et al (2014) who reported that water deficiency resulted in an increase in the accumulation of reducing sugar in Brassica napus. Polythelene glycol of 10 to 30%, increased total sugar content in the root of rice seedlings from 24 to 72 hrs of application and 20% PEG increased total sugar content in the root by 20.0 and 50.13% at 24 and 72 hrs of treatment, respectively.…”

Effects of water deficit induced by polyethylene glycol (PEG-6000) on rice grown in half strength Hoagland solution was studied in the present investigation. Impacts of different water stress (10, 20 and 30% PEG) on some physiological and biochemical characteristics were determined in this investigation. Results showed that water stress significantly affected most physiological and biochemical characteristics. The increasing water stress declined the root and shoot length and fresh and dry weights of root and shoot. An increase in water stress also resulted in reduction of relative water content, leaf pigments and protein content. Upon dehydration, an incline in reducing and total sugar and proline content were evident in the root and shoot of rice. Water-deficit stress resulted in higher superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities but as the severity of the water stress increased, the SOD activity decreased. These crucial characteristics would be expected to be utilized as screening techniques for water stress tolerance to the future development of new variety. Bangladesh J.

“…Polyethylene glycol generated osmotic stress decreased the chlorophyll content in Thymus vulgaris (Razavizadeh et al 2019). Water deficiency increased sugar accumulation in Brassica napus (Ali et al 2014). Due to water stress a significant increase in proline content was observed in sweet basil (Al-Huqail et al 2020).…”

“…Zhang et al [125] observed that exogenous K applications increase the Pro content in Z. mays cultivars under drought conditions. At the same time, Ali et al [126] reported that under drought stress, K applications increase the shoot Pro content in B. napus in a dose-dependent manner. Similarly, Zahoor et al [127] found that K application generates the Pro content in G. hirsutum during drought stress.…”

Potassium: A Vital Regulator of Plant Responses and Tolerance to Abiotic Stresses

et al. 2018

Among the plant nutrients, potassium (K) is one of the vital elements required for plant growth and physiology. Potassium is not only a constituent of the plant structure but it also has a regulatory function in several biochemical processes related to protein synthesis, carbohydrate metabolism, and enzyme activation. Several physiological processes depend on K, such as stomatal regulation and photosynthesis. In recent decades, K was found to provide abiotic stress tolerance. Under salt stress, K helps to maintain ion homeostasis and to regulate the osmotic balance. Under drought stress conditions, K regulates stomatal opening and helps plants adapt to water deficits. Many reports support the notion that K enhances antioxidant defense in plants and therefore protects them from oxidative stress under various environmental adversities. In addition, this element provides some cellular signaling alone or in association with other signaling molecules and phytohormones. Although considerable progress has been made in understanding K-induced abiotic stress tolerance in plants, the exact molecular mechanisms of these protections are still under investigation. In this review, we summarized the recent literature on the biological functions of K, its uptake, its translocation, and its role in plant abiotic stress tolerance.

“…The resistance of cultivars to biotic and abiotic stresses is particularly important (Khalil et al, 2022). This problem was undertaken among others by Ali et al (2014) who proved a significant effect of oilseed rape cultivar on water deficit stress. These authors also showed a significant differentiation of yields of the assessed cultivars as a result of the use of a factor limiting the stress of water shortage, i.e.…”

The effect of three fungicide treatment programmes and the level of spring nitrogen fertilisation on the seed yield of two types ofcultivars of Brassica napus L. sown at two different seeding rates was studied in a field experiment. The subject of the study was anopen-pollinated cultivar ‘Casoar’ and a restored hybrid cultivar ‘Visby’. Three plant protection programmes, two levels of spring nitrogenfertilisation (160 and 220 kg N⋅ha1), and two different seeding rates for each cultivar (‘Visby’—50 and 70 seeds⋅⋅m2; ‘Casoar’—60 and 80 seeds⋅m2) were included. The most intensive protection programme comprised three fungicide treatments: first in autumn at the six-leaves-unfolded stage—BBCH 16, second in spring at the stem elongation stage—BBCH 33, and third at the full flowering stage—BBCH 65. One of two less intensive programmes of plant protection included fungicide application in autumn at the sixleaves-unfolded stage—BBCH 16 and at the full flowering stage—BBCH 65, while the second included fungicide application in spring at the stem elongation stage—BBCH 33 and at the full flowering stage—BBCH 65. The effectiveness of the protection programmes and nitrogen fertilisation was influenced by the intensity of abiotic stress factors. The average yield from the plots protected against pathogens was significantly higher than that from the untreated plots. The increase of nitrogen fertilisation from 160 to 220 kg⋅ha1 also caused a significant increase of average seed yield. The yield of cultivar ‘Visby’ was higher and less dependent on the seeding rate compared to cultivar ‘Casoar’.Keywords: Winter oilseed rape; Cultivars; Disease control; Nitrogen fertilisation; Seeding rate; Sclerotinia sclerotiorum; Leptosphaeria spp.; Alternaria spp. Botrytis cinerea.
