Abstract Chilling is one of the major abiotic stresses for plants, especially for rice cultivation. Many essential metabolic processes for growth and development are temperature-dependent. In that case, reducing the negative effects of cold stress using exogenous chemicals is a possible option. Therefore, the current study examined the effects of pre-sowing seed treatment with different chemicals, viz. hydrogen peroxide (H₂O₂), salicylic acid (SA), calcium chloride (CaCl₂), thiourea (TU), and citric acid (CA) on the germination of rice seeds (cv. BRRI dhan28) under chilling environments. Rice seeds were soaked in distilled water (control), 10 mM CA, 2 mM SA,… More >

Abstract Marigolds (Tagetes spp.) are popular horticultural plants worldwide. The current study aimed to investigate the optimal mutagenic conditions for marigold seeds using EMS (ethyl methanesulfonate) mutagenesis. Different concentrations and treatment times of EMS were applied to investigate their effects on the marigold seed germination rate, growth traits, antioxidant enzyme activities (i.e., SOD and POD), and malondialdehyde (MDA) contents. Results indicated that with increasing the EMS treatment duration and concentration, the seed germination rate and growth treatments were reduced, accompanied by elevated MDA content. In addition, SOD and POD activities initially correlated positively with the growth tratis at More >

Abstract Camellia petelotii (Merr.) Sealy is an endangered Chinese native species that originates from Guangxi Zhuang Autonomous Region, China. Previous research demonstrated that proper water and fertilizer treatments could improve the growth and quality of Camellia species. This study uses a three-factor, five-level quadratic rotational combination experimental design to investigate the impact of water-fertilizer coupling on plant growth characteristics and the most suitable treatment for 24-month-old grafted C. petelotii seedlings. The experimental design includes irrigation levels [30%, 40%, 55%, 70%, 80% of field capacity (FC)], nitrogen application (0, 2.17, 5.43, 8.70, 10.87 g·plant⁻¹), and phosphorus application (0, 0.96, 2.40,… More >

Abstract In this study, we analyzed the agronomic and physiological indicators of the leaves and roots of 60 hulless barley varieties under low-temperature treatment, identified the crucial indicators that can reflect the ability of hulless barley to tolerate low-temperature, and evaluated the ability of different hulless barley varieties to tolerate low-temperature. The results indicated significant differences in the agronomic and physiological indicators of 60 hulless barley varieties subjected to low-temperature treatment. Most of the agronomic indicators significantly decreased, whereas most of the physiological indicators significantly increased. However, the magnitude of changes in each agronomic and physiological… More >

Abstract Rice (Oryza sativa L.) is one of the most important cereal crops in the world. Bakanae disease is a significant rice disease widely distributed in rice-growing regions worldwide. Therefore, the present investigation aimed to assess the optimal concentrations of paclobutrazol (PBZ) as a treatment for rice grains (cv. Sakha 108) to control bakanae disease, also evaluating its impact on grain germination, seedling growth parameters as well as disease index. Paclobutrazol concentrations had no significant impact on seed germination, regardless of whether the seeds were incubated with Fusarium fujikuroi or not. Application of PBZ, either alone or in… More >

Abstract Soybean (Glycine max) is a potential legume crop, but it cannot thrive in mild salinity. Salicylic acid (SA) is a renowned plant growth hormone that improves tolerance to saline conditions. Hence, the study was performed to understand the functions of priming seeds and supplementation of SA in modulating salt tolerance in soybean seedlings. When exposed to salt stress, soybean seedlings showed considerably higher contents of hydrogen peroxide (H₂O₂) and malondialdehyde (MDA) while having decreased germination and growth factors, water contents, and photosynthetic pigments. The germination rate, final germination percentage, germination index, germination energy, and seed vigor index… More >

Abstract Salinity is a major abiotic stress that hinders plant development and productivity and influences agricultural yield. Seed priming is a technique used to boost germination and seedling growth under abiotic stress. A pot experiment was conducted to evaluate the impact of seed priming with potassium nitrate (KNO₃) at various levels (0%, 0.50%, 1.00% and 1.50%) under salt stress (0, 75, 100 mM NaCl) on two maize verities (MNH360 and 30T60) for the growth, development and metabolic attributes results revealed that in maize variety MNH360, KNO₃ priming’s significantly enhanced growth parameters than in maize variety 30T60 under… More >

Abstract Leaves are important ‘source’ organs that synthesize organic matter, providing carbon sources for plant growth. Here, we used Populus talassica × Populus euphratica, the dominant species in ecological and timber forests, to simulate carbon limitation through artificial 25%, 50%, and 75% defoliation treatments and explore the effects on root, stem, and leaf morphology, biomass accumulation, and carbon allocation strategies. At the 60th d after treatment, under 25% defoliation treatment, the plant height, specific leaf weight, root surface area and volume, and concentrations of non-structural carbohydrates in stem and root were significantly increased by 9.13%, 20.00%, 16.60%,… More >

Abstract Understanding how summer warming influences the parent and daughter shoot production in a perennial clonal grass is vital for comprehending the response of grassland productivity to global warming. Here, we conducted a simulated experiment using potted Leymus chinensis, to study the relationship between the photosynthetic activity of parent shoots and the production of daughter shoots under a whole (90 days) summer warming scenario (+3°C). The results showed that the biomass of parents and buds decreased by 25.52% and 33.45%, respectively, under warming conditions. The reduction in parent shoot biomass due to warming directly resulted from decreased… More >

Abstract Seed priming is a pre-germinated technique that can enhance seed germination percentage, faster and synchronized germination, better seedling growth, and yield under stress conditions. To ascertain the most effective seed priming method that would ensure the potential yield of wheat in Bangladesh, two experiments were carried out from December 2021 to March 2022 at the Department of Agronomy, Bangladesh Agricultural University. Two wheat varieties namely BARI Gom-28 and BWMRI Gom-1 were subjected to a range of priming chemicals in both lab and pot tests. These compounds included the following: control (no priming), hydropriming (distilled water),… More >
