“…Plants have developed different mechanisms to protect their cells under stress conditions that are not suitable for them. Proline accumulation is one of these mechanisms and is effective as an osmotic preservative [27,28]. Our research also examined the treatment of lead causing to stress in plants and it is seen that the osmotic regulation in question also occurs there.…”

“…In a previous study carried out with cold stress resistant and sensitive sugar cane cultivar, cell structure was destructed and cold stress-induced plants had greater MDA, proline, soluble sugar, soluble protein, POD and SOD activity than the control plants (Sun et al, 2017). It was reported in another study investigating the effects of cold stress on rye and wheat seedlings that cold stress increased antioxidant enzyme activities, proline, sugar and anthocyanins contents of both species (Kolupaev et al, 2016). Significant decreases were reported in malondialdehyde, proline, peroxidase and catalase activities of control and transgenic tomato plants under cold and low temperature stress (Yu et al, 2015).…”

Low temperatures slow down plant growth and development and generate physiological damages on plants. Metabolism of largely produced and consumed common bean (Phaseolus vulgaris L.) plants decelerates at temperatures below 15 °C. This study was carried out at Van Yuzuncu Yil University in Van province of Turkey with limited vegetation period due to its cold climate in winter. In this study, the bean plants were subjected to low temperature stress and catalase (CAT), super oxide dismutase (SOD), ascorbate peroxidase (APX) enzyme activities, malondialdehyde (MDA), chlorophylla, chlorophyll-b and total chlorophyll, K, Ca, and Mg ion contents of low temperature stress-tolerant Yakutiye and Ç30 and low temperature stress-sensitive Zulbiye and Ç13 bean genotypes were measured on 25 th , 30 th , 35 th and 40 th days of low temperature stress. Four bean seeds were sown in 2-liter pots filled with 2:1 peat:perlite mixture as to have 2 plants in each pot. The pots were irrigated with Hoagland nutrient solution. Low temperature stress plants were sown on 15 th of March with low outdoor temperatures. In control group, been seeds were sown on 25 th of April and plant samples were taken in again 5-day intervals in 4 periods (25 th , 30 th , 35 th and 40 th days of growth). Significant differences were observed in enzyme activities, chlorophyll contents and ion contents of low temperature-tolerant and sensitive bean genotypes in 4 measurement periods.

“…Plants resist these unsuitable environmental conditions by modifying ion accumulation producing osmoregulators such as proline to assist the plant in completing its life cycle (Kolupaev et al, 2016). Proline modifies the osmotic property of the plant against the risks of salinity and drought stresses and other shocks.…”

The current research aims to determine whether salinity in irrigation water, frost, drought, and heat damage to cucumbers may be reduced or avoided by using manufactured nano-silica (NaSiPs) particles. After soaking the seeds for 3 hours in a nano-silica suspension, seedlings with a length of 15 cm in the greenhouse were sprayed with various NaSiPs concentrations (0, 100, 200, and 400 mg L -1 ). When the plant reached 30 cm in length, the various shock treatments were applied. At harvest, some vegetative parameters were determined as well as chemical analysis of plants (root, leaves , and fruits). The results confirmed that NaSiPs were effective in reducing the negative effects of various shocks on plant biometrics, chlorophyll, and fruit yield. The findings revealed that there were no significant effects of the two-way interaction between shock treatments and nanosilica rates on the plant biometrics, chlorophyll, and fruit yield. The concentrations of sodium and potassium in roots, leaves, and fruits, as well as silicon and proline in roots and leaves, were found to have the same effects. Except for Na and K in fruits and leaves, all parameters studied increased with increasing nano-silica rates, with the exception of fruit sodium and leaf potassium concentration. The shocks had the following order: control > salinity > frost > dryness > heat. SiNP400 treatment of plants reduced the negative effects of various shocks.
