“…Other stimulating factors (chemical), such as, e.g., salts, caused an increase in the chlorophyll content of white clover leaves [55] and certain alfalfa cultivars [12]. In another study, no significant increase in the chlorophyll content of alfalfa leaves was noted after exposing the whole plant to microwave irradiation [56].…”

The experimental material consisted of leaves obtained from 6-and 2-year-old alfalfa plants. Samples were obtained from a field experiment. One day prior to sowing, seeds were stimulated using He-Ne laser light with a surface power density of 6 mW•cm-2-free-fall exposure (L) repeated three times; alternating magnetic field with 30 mT induction and 30 s (P) exposure time; and a combination of laser light and magnetic field (L+P). The results of the stimulation treatments were referenced to non-stimulated samples (control-K). The obtained values of fluorescence lifetime varied from 8.98 to 12.90 ns (t1) and from 3.84 to 5.14 ns (t2). The physical factors applied caused an extension of the lifetimes (t1 and t2), as well as an increase in the chlorophyll a and carotenoid content in 6-year-old cv. Radius leaves, as compared to the control. Contrary observations (i.e., a decrease in the aforementioned indicators) were made for cv. Ulstar (old). In the case of magnetic field stimulation, the longest fluorescence lifetimes, the highest concentrations of chlorophyll a and carotenoids were noted for cv. Radius (old). The content of chlorophyll a was significantly higher in young Lucerne than in older plants.

“…The plant material was centrifuged (1.0 min, 14,000 rpm) and 400 mL of clear supernatant was mixed with 600 mL of acidic methanol. Absorption of each sample was determined at 530 and 657 nm in a double-beam UV-vis spectrophotometer (HITACHI U-2900 spectrophotometer) [6].…”

“…Though extreme heat events may have the most dramatic impact on plant output, nevertheless there has been very little work carried out to document these effects. China also suffers considerably from climate change [6]. From 1960 to 2009, high-temperature stress caused by global warming has been extensively reported in the major planting areas in China [7][8][9][10].…”

The present study investigated the influences of different day and night temperature regimes on the growth of violet rape (Brassica rapa var. chinensis) and pinpointed the optimal temperature combination for both yield and quality of the plant. For this purpose, the plants were grown under 6 temperature combination conditions: W1 (30/20ºC, 12-h light/12-h dark), W2 (25/15ºC, 12-h light/12-h dark), W3 (20/10ºC, 12-h light/12-h dark), W4 (30/15°C, 12-h light/12-h dark), W5 (25/10ºC, 12-h light/12-h dark), and W6 (30/10ºC, 12-h light/12-h dark), and in addition we measured various morphological, yield, and biochemical traits. Results demonstrated that temperature regimes considerably affected the growth parameters of the violet rape compared with control. The W3 treatment with an average temperature of 20/10ºC displayed the highest plant growth traits, including plant height (12.74±0.24 cm), leaf length (8.20±0.08 cm), leaf width (5.44±0.16 cm), and leaf area (33.46±0.83 cm²). Moreover, a highly significant correlation (p<0.05) was found between temperature and soluble protein, chlorophyll, anthocyanin, nitrate nitrogen contents, and root activity; whereas the vitamin C and soluble sugar contents remained significantly unaffected except in the W1 treatment, under different temperature combinations between day and night. This study concluded that high temperature exerts an adverse effect on plant growth, and therefore a low day and night temperature combination is suggested in order to achieve high yield and quality for irrigated violet rape.

“…On the other hand, from the agricultural perspective, one of the drawbacks of this plant is its susceptibility to salinity and drought stress conditions. Previous studies have demonstrated that yield and quality of white clover grown under these stress conditions significantly decreased (Wang et al, 2010;Khalid et al, 2017). Therefore, there is a need for developing tolerant white clover lines that can tolerate such abiotic stresses without having any quality and yield loss.…”

The aim of this study was to confirm the presence of BADH gene and control whether it plays an important role to protect white clover (Trifolium repens L.) against oxidative, salt, and drought stresses. Three genotypes possessing BADH and 1 genotype lacking BADH were selected, considering the expression levels of BADH in response to methyl viologen mediated oxidative stress. The genotypes possessing BADH displayed significantly less ion leakage under oxidative stress treatment, compared to that lacking BADH. In order to test salinity tolerance, the plants were treated with 300 mM NaCl for 2 weeks, and to mimic drought conditions, plants were grown without irrigating for 5 days. Under the salt stress, the plants possessing BADH contained lower malondialdehyde levels and higher chlorophyll contents than that of plants lacking BADH. Similarly, under the drought conditions, the plants possessing BADH were found to have increased levels of glycinebetaine, proline, and high relative water contents than the plant lacking BADH. These findings indicate that the plants having BADH exhibited enhanced tolerance to salt and drought stresses. These enhanced tolerances of plants possessing BADH gene is attributed to its ability to induce glycinebetaine synthesis. Moreover, the plants possessing BADH were found to exhibit higher relative feed value under both stress and normal conditions. These plants could be used as forage crops on marginal areas having salinity or drought problems.
