“…Peroxidase is more effective than catalase due to its protective action in removing H2O2 (56). Comparable results were observed in Phaseolus vulgaris (57) and Triticum aestivum (58). Free radicals like O2 and H2O2 accumulation by gamma radiation distressed the system for removing them and caused lipid peroxidation.…”

Mutation breeding plays a vital role as a source of genetic diversity to improve plant growth and development. Green gram (Vigna radiata (L.) R. Wilczek) “Vamban 2” variety was selected for this investigation. The doses applied to the healthy seeds of green gram were 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy, 600 Gy, 700 Gy and 800 Gy and non-treated seeds were kept as control throughout this study. A lethal dose (LD50) was observed at 500 Gy, whereas seedling length, fresh and dry weight decreased as the applied doses increased while compared to the control. Irradiated seedlings showed a decreased content of chlorophyll a compared to Chlorophyll b and increased carotenoid content compared to the control. Biochemical characteristics such as reducing sugar, starch, protein, amino acid and proline content were increased and noted maximum at 800 Gy. Antioxidants and lipid peroxidation (MDA) increased gradually along with increasing doses. FTIR analysis exhibited maximum functional groups at 600 Gy and ESR data showed ample hyperfine range of structure at 500 Gy, 600 Gy and 700 Gy. This investigation found considerable alterations in morphology, photosynthetic pigment, biochemical characteristics and antioxidant analyses, which suggest an idea to select an appropriate dose of gamma irradiation in green gram for successive breeding program.

In order to screen the sweet corn varieties with strong cadmium tolerance and explore the differences in response to cadmium stress, 12 sweet corn varieties mainly selected in South China were used to study the effects of cadmium treatment. The seedling grew in sand culture until they initiated three leaves in total with two leaves expanded and treated with cadmium ion (Cd 2+ ) solution, and then phenotypic investigation of seedling height, main root length, total root number, fresh weight, dry weight, and SPAD value of the first leaf. The results showed that there were significant differences under cadmium tolerance to those sweet corn varieties with different genetic backgrounds, and most of the eight characters measured had significant correlations between cadmium tolerance indices. A comprehensive index obtained by principal component analysis can effectively evaluate the cadmium tolerance of different varieties of sweet corn, and its contribution rate is 73.42%. Cluster analysis was used to classify 12 sweet corn varieties into sensitive (one variety), intermediate (eight varieties) and tolerant (three varieties). Among them, three varieties including 'Zhongxiantian 102', 'Zhuyutian 1' and 'Fotian 10' had strong cadmium tolerance, which could be further screened for low-cadmium-accumulating varieties to be used in agricultural production. At the same time, by comparing and analyzing the phenotypic variation between two varieties with different response to cadmium stress, it was found that cadmium stress would break the stability of chlorophyll in the leaves of sensitive sweet corn seedlings, affecting photosynthesis, and then reducing the accumulation of biomass and inhibiting growth and development. This study provides reference for further analysis of cadmium-resistant response mechanism of sweet corn.

“…Then, the Brassica napus seeds were placed in deionized water (T2) and isosteviol at solution concentrations of 10 −10 (T3), 10 −9 (T4), 10 −8 (T5), 10 −7 (T6), and 10 −6 M (T7) for 24 h. Then, the Brassica napus seeds were removed and placed into Petri dishes with double layers of filter paper (50 grains per dish). According to the results of the previous test [ 16 ], 20 mL of NaCl solution at a concentration of 140 mM was separately added to the above six treatment groups for stress treatment. Seeds soaked in deionized water and stressed without NaCl solution (20 mL of deionized water) were used as the control group (T1), and each group of experiments had 5 replications.…”

“…Isosteviol is a tetracyclic diterpenoid with a beyerane skeleton that was first reported by Mosetling and Nes in 1955 [ 14 , 15 ]. Recently, studies have shown that isosteviol has biological activities similar to those of gibberellin in alleviating abiotic stress in plant seedlings [ 16 , 17 ]. For example, Wang et al (2022a) found that soaking seeds in isosteviol (10 −9 ~10 −8 M) could effectively relieve the growth inhibition effect of chromium stress on wheat seedlings, thereby improving the stress tolerance of wheat [ 18 ].…”

In this paper, the effect of isosteviol on the physiological metabolism of Brassica napus seedlings under salt stress is explored. Brassica napus seeds (Qinyou 2) were used as materials, and the seeds were soaked in different concentrations of isosteviol under salt stress. The fresh weight, dry weight, osmotic substance, absorption and distribution of Na+, K+, Cl−, and the content of reactive oxygen species (ROS) were measured, and these results were combined with the changes shown by Fourier transform infrared spectroscopy (FTIR). The results showed that isosteviol at an appropriate concentration could effectively increase the biomass and soluble protein content of Brassica napus seedlings and reduce the contents of proline, glycine betaine, and ROS in the seedlings. Isosteviol reduces the oxidative damage to Brassica napus seedlings caused by salt stress by regulating the production of osmotic substances and ROS. In addition, after seed soaking in isosteviol, the Na+ content in the shoots of the Brassica napus seedlings was always lower than that in the roots, while the opposite was true for the K+ content. This indicated that under salt stress the Na+ absorbed by the Brassica napus seedlings was mainly accumulated in the roots and that less Na+ was transported to the shoots, while more of the K+ absorbed by the Brassica napus seedlings was retained in the leaves. It is speculated that this may be an important mechanism for Brassica napus seedlings to relieve Na+ toxicity. The spectroscopy analysis showed that, compared with the control group (T1), salt stress increased the absorbance values of carbohydrates, proteins, lipids, nucleic acids, etc., indicating structural damage to the plasma membrane and cell wall. The spectra of the isosteviol seed soaking treatment group were nearly the same as those of the control group (T1). The correlation analysis shows that under salt stress the Brassica napus seedling tissues could absorb large amounts of Na+ and Cl− to induce oxidative stress and inhibit the growth of the plants. After the seed soaking treatment, isosteviol could significantly reduce the absorption of Na+ by the seedling tissues, increase the K+ content, and reduce the salt stress damage to the plant seedlings. Therefore, under salt stress, seed soaking with isosteviol at an appropriate concentration (10−9~10−8 M) can increase the salt resistance of Brassica napus seedlings by regulating their physiological and metabolic functions.
