“…Panković et al [ 58 ] documented that Cd inhibitory effects improved sunflower’s nitrogen uptake. With rising Cd concentrations, a persistent trend of decreased shoot and root length was found in chili crop plants [ 59 ]. Cadmium toxicity inhibits plant growth, reducing root dry weight, diameter, and the number of lateral roots in Massai grass [ 60 ].…”

Heavy metal cadmium (Cd) naturally occurs in soil and is a hazardous trace contaminant for humans, animals, and plants. The main sources of Cd pollution in soil include overuse of phosphatic fertilizers, manure, sewage sludge, and aerial deposition. That’s why an experiment was conducted to analyze the effect of Cd toxicity in Capsicum annuum L. by selecting its seven varieties: Hybrid, Desi, Sathra, G-916, BR-763, BG-912, and F1-9226. Cadmium was spiked in soil with four levels, i.e., (0, 3, 4, and 5 mg Cd kg− 1 of soil) for a week for homogeneous dispersion of heavy metal. Chili seeds were sown in compost-filled loamy soil, and 25-day-old seedlings were transplanted into Cd-spiked soil. Cadmium increasing concentration in soil decreased chili growth characteristics, total soluble sugars, total proteins, and amino acids. On the other hand, the activities of antioxidant enzymes were increased with the increasing concentration of Cd in almost all the varieties. Treatment 5 mg Cd/kg application caused − 197.39%, -138.78%, -60.77%, -17.84%, -16.34%, -11.82% and − 10.37% decrease of carotenoids level in chili V2 (Desi) followed by V4 (G-916), V1 (Hy7brid), V7 (F1-9226), V6 (BG-912), V5 (BR-763) and V3 (Sathra) as compared to their controls. The maximum flavonoids among varieties were in V5 (BR-763), followed by V6 (BG-912), V7 (F1-9226), V3 (Sathra) and V1 (Hybrid). Flavonoids content was decreased with − 37.63% (Sathra), -34.78% (Hybrid), -33.85% (G-916), -31.96% (F1-9226), -31.44% (Desi), -30.58% (BR-763), -22.88% (BG-912) as compared to their control at 5 mg Cd/kg soil stress. The maximum decrease in POD, SOD, and CAT was − 31.81%, -25.98%, -16.39% in chili variety V7 (F1-9226) at 5 mg Cd/kg stress compared to its control. At the same time, maximum APX content decrease was − 82.91%, followed by -80.16%, -65.19%, -40.31%, -30.14%, -10.34% and − 6.45% in V4 (G-916), V2 (Desi), V3 (Sathra), V6 (BG-912), V1 (Hybrid), V7 (F1-9226) and V5 (BR-763) at 5 mg Cd/kg treatment as compared to control chili plants. The highest CAT was found in 5 chili varieties except Desi and G-916. Desi and G-916 varieties. V5 (BR-763) and V6 (BG-912) were susceptible, while V1 (Hybrid), V3 (Sathra), and V7 (F1-9226) were with intermediate growth attributes against Cd stress. Our results suggest that Desi and G-916 chili varieties are Cd tolerant and can be grown on a large scale to mitigate Cd stress naturally.

Aims and Background The growing human population and scarcity of new arable land necessitate exploring contaminated lands for agriculture production. Intercropping, a strategic method involving different plant species to enhance plant biomass, soil health and phytoremediation, thus promoting sustainable agricultural practices on contaminated lands. Therefore, the selection of suitable intercropping systems is of great interest for sustainable agriculture. Methods This research focused on the phytoremediation potential of rapeseed and kenaf in cadmium-contaminated soil, evaluating their performance in both intercropping and monoculture system. Additionally, it examined the growth, morphological, and physicochemical responses of the plants. Results The results revealed that intercropping of these two species significantly enhanced their biomass production, chlorophyll content, and photosynthetic efficiency compared to monocultures. Antioxidant enzyme activities in both plants were elevated under intercropping, reducing oxidative stress markers such as malondialdehyde (MDA) and superoxide anion (O2−). Intercropping increased Cd accumulation in both shoots and roots of kenaf and rapeseed, correlating with a decrease in soil pH and an increase in available Cd content in the soil. Both species showed potential for metal phytostabilization, with BCF > 1 and TF < 1 in intercropping. It is also found that intercropping enhanced the activity of soil enzymes, urease and catalase while reducing sucrase activity, indicating improved soil health and microbial activity. Conclusion These findings suggest that intercropping kenaf and rapeseed not only improves plant growth and Cd uptake but also promotes better soil health and resilience under Cd stress, offering a sustainable approach for phytoremediation in contaminated soils.

“…This type of genetic mechanism (mainly recessive) has been studied for a great number of cultivated plants, primarily within the framework of radiobiological and radioecological researches, and at least two such possible loci have been identified, there could be other loci. However, the mechanism of genetic tolerance to the action of chemical supermutagens is much less understood, although it is already clear that those mechanisms are more specific and characterized by a significantly greater diversity in plant response than sensitivity to ionizing radiation (Abdelsalam et al, 2019;Hasan et al, 2022).…”

“…At the current level of understanding, the main cause of spontaneous mutagenesis is repair errors and the mobility of the genome of a cultivated plant. Other reasons are rare and unlikely (Hasan et al, 2022). The ecological-genetic approach in experimental mutagenesis begins with complex studies: first of all, recording radiobiological effects of a mutagenic action, then identifying specific DNA-disruption at the molecular level, determining the relationship between phenological variability and specific changes in DNA (Bondarenko & Nazarenko, 2020), and seeking for variations of a resulting change and identifying the limits of variability in the manifestation of a changed trait or group of key traits (Bhat & Wani, 2017;Spencer-Lopes et al, 2018).…”

The analysis of cytogenetic activity is a key component in determining prospects of future hereditary variability after, subject to a certain mutagenic factor, primarily identifying the significance of the genotype-mutagenic interaction, the correctness of the selected concentrations for more thorough screening of some development parameters. Winter wheat seeds of eight varieties (Balaton, Borovytsia, Zeleny Gai, Zoloto Ukrainy, Kalancha, Niva Odeska, Polyanka, Pochayna) were subjected to ЕМS (ethylmethansulfonate) at the concentrations of 0.025%, 0.05%, 0.10% The exposure lasted for 24 hours. Cytogenetic analysis was carried out for pollen fertility; we also examined the rates and spectras of chromosomal rebuildings in proper cell devision phases in relation to plant gcnotype and concentration of the mutagen. The experiment was aimed at identification of interrection between geotype, concentration of mutagen and mutagen nature, determining genome response to mutagen action. Such indicators of cytogenetic activity as the total rate of chromosomal abnormalities, fragments and double fragments, single and double bridges, micronucleus and lagging chromosomes were studied. The selected concentrations of the mutagen significantly influenced all the analyzed parameters, they can be attributed to the optimal and high range of concentrations according to the nature of the impact on bread wheat. We determined that in the case of the mutagenic action, the genotype had a significantly lesser effect on the nature and rate of individual aberrations than an increase in the concentration, while having a significant effect on the rate of increase in pollen sterility. The mutagen was characterized by a significantly lower site-specificity at the cellular level than other chemical supermutagens, manifesting only in the correlation between individual types of aberrations, but not in the character of the increase in their number. The key parameter to identify the activity of this agent was the frequency of fragments and double fragments, their ratio with bridges.
