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 Physcomitrium eurystomum Sendtn. is a very rare European ephemeral funaroid moss. The entire European population of this species is considered threatened and it is red-listed in many regions and countries. In addition to being recognized as threatened and included in nature conservation legislation, it also requires active protection measures. This study aims to contribute to effective conservation practices for P. eurystomum. Different conservation physiology tests were carried out to propagate this species to achieve a reliable procedure for biomass production and the potential reintroduction of germplasm. Ex situ tests, both in vitro and ex vitro, were carried out to determine… 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 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 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 >

Abstract To mitigate the wastage of seed resources and reduce the usage of pesticides and fertilizers, seed coating agents have gained popularity. This study employs single-factor and multi-index orthogonal experimental design methods to investigate the seed coating formula and physical properties of Tartary buckwheat. The specific effects of each component on Tartary buckwheat seed germination are analyzed. The findings reveal that the seed coating agent formulated with 1.5% polyvinyl alcohol, 0.15% sodium alginate, 0.2% op-10, 0.1% polyacrylamide, 8% colorant, 3% ammonium sulfate, 1% potassium dihydrogen phosphate, and 0.15% carbendazim exhibits the most effective coating. It demonstrates… More >

Abstract In a greenhouse experiment, the effects of soil microorganisms and extracts of Achnatherum inebrians on the seed germination and seedling growth of Elymus nutans were studied. The results showed that both the extracts from aboveground and belowground parts of A. inebrians significantly inhibited the germination rate, germination potential, germination index, vigor index, seedling height, root length, and fresh weight of E. nutans, but increased malondialdehyde content, catalase, peroxidase and superoxide dismutase activity of E. nutans seedlings (p < 0.05). The allelopathy of aqueous extracts of the aboveground parts of A. inebrians was stronger than that of the precipitates. Aqueous extracts of the… More >

Abstract Gossypium hirsutum L. is an important cash crop native to the subtropics and is widely cultivated around the world. Low temperature is an important stress that seriously affects seed germination and emergence during planting. In this study, transcriptomic profiles of low-temperature- and normal-temperature-germinated seeds of Xinluzao 25, a variety with low-temperature tolerance and high germination rates, were analyzed and compared. The following results were obtained. (1) A total of 81.06 Gb of clean data were obtained after transcriptome sequencing and assembly, and 76,931 non-redundant Unigene sequences were obtained after data consolidation and concatenation; of these, 69,883… More >

Abstract Ilex asprella (Hook. et Arn.) Champ. ex Benth is one of the most important traditional Chinese medicines in southern China. The seeds of Ilex asprella usually have extremely low germination due to their dormancy characteristics, which severely impacts the efficiency of seedling raising and increases labor costs. In this study, to improve the seed germination of I. asprella, the effects of germination substrate, hormone, winnowing, and stratification treatments on the seed germination of I. asprella were investigated. The results of the germination matrix showed that the highest germination percentage of 45.2% was achieved under the 20°C/10°C day/night temperature and… More >

Abstract Abscisic acid (ABA) is involved in regulating diverse biological processes, but its signal transduction genes and roles in hemp seed germination are not well known. Here, the ABA signaling pathway members, PYL, PP2C and SnRK2 gene families, were identified from the hemp reference genome, including 7 CsPYL (pyrab-actin resistance1-like, ABA receptor), 8 CsPP2CA (group A protein phosphatase 2c), and 7 CsSnRK2 (sucrose nonfermenting1-related protein kinase 2). The content of ABA in hemp seeds in germination stage is lower than that in non-germination stage. Exogenous ABA (1 or 10 μM) treatment had a significant regulatory effect on the selected PYL,… More >
