Abstract The cultivation of Soledad pepper (Capsicum annuum L.) is essential in Oaxaca and Veracruz, but it faces issues with pests and diseases, which affect yield and cause economic losses. To mitigate these impacts, farmers have started using biostimulants such as chitosan and plant growth promoting bacteria instead of agrochemicals due to their environmental and health benefits. This study evaluated the effect of Bacillus subtilis and chitosan, both individually and combined, on the growth, yield, and fruit quality of Soledad pepper under greenhouse conditions. Four treatments were applied at different stages of the crop cycle: Q (Chitosan), BS (Bacillus More >

Abstract Water scarcity is an escalating global challenge that severely threatens productivity and reproductive success in crops, particularly in drought-sensitive species such as Capsicum annuum L. Although deficit irrigation strategies are widely recommended to enhance water use efficiency, knowledge remains limited regarding their interactions with soil amendments such as biochar and the consequent impacts on reproductive traits. This study aimed to evaluate the combined effects of deficit irrigation strategies and biochar application on pollen viability and morphology in Capsicum annuum. The experiment was conducted under full, partial, and deficit irrigation regimes with and without biochar treatment, following a… More >

Abstract Hot pepper (Capsicum annuum var. conoides) is a significant vegetable that is widely cultivated around the world. Currently, global climate change has caused frequent severe weather events, and waterlogging stress harms the pepper industry by affecting the planting period, growth conditions, and disease susceptibility. The gene CaABI3/VP1-1 could improve pepper waterlogging tolerance. In order to explore the upstream regulatory mechanism of CaABI3/VP1-1, a high-quality standardized yeast hybrid library was successfully constructed for yeast one-, two-, and three-hybrid screening using pepper ‘ZHC2’ as the experimental material, with a library recombinant efficiency of up to 100%. The length of inserted… More >

Abstract Bell pepper (Capsicum annuum L.), along with potato and tomato, is one of the three most cultivated vegetables in the world. Bell pepper is worldwide accepted due to its characteristics of color, smell, flavor, and texture. Bell pepper is also considered a nutritious food due to its vitamin and antioxidant contents. In Mexico, bell pepper production has a high value because it is grown for the international markets, particularly the United States of America. Nevertheless, the abscission of flowers and fruits is a factor that limits the yield, hinders the planning of activities, and causes a More >

Abstract Hot pepper (Capsicum annuum L.) is consumed as one of the oldest domesticated crops all over the world. Although mutation breeding using radiation has been performed in hot peppers, little is known about the comparative analysis of mutagenic effects at the molecular level by ion beam irradiation. To comprehend the response mechanism of hot pepper to the ion beam, we used a mutant with favorable economic characteristics induced by lithium-ion beam irradiation to investigate the biological effects. The results indicated that the lithium-ion beam had a positive effect on important agronomic traits, particularly yield unit, but… More >

Abstract Intercropping of crops that can secrete bacteriostatic active substances can not only inhibit the occurrence of disease but also have an important effect on plant growth. However, the effects of dandelion intercropping on pepper blight control and pepper growth remain unclear. In this study, the control effect of dandelion on pepper blight was studied by inoculating the pepper leaves with Phytophthora infestans, and it also discusses the correlation of the occurrence of pepper epidemic disease with the pepper canopy environment, soil environment, pepper photosynthesis, and yield index. The results showed that best plant distance for dandelion… More >

Abstract Waterlogging is an illustrious abiotic stress and the constrictions it enforces on plant roots have negative effects on growth and development. This study was undertaken to investigate waterlogging stress tolerant potential in chilli (Capsicum annum L.) genotypes through evaluating morphological, physiological, biochemical and anatomical parameters. Thirty-five days old seedlings of 10 chilli genotypes were exposed to waterlogging stress maintaining water height 3–5 cm over the soil surface artificially for three days. This duration (36–38 DAE) was termed as waterlogging period, and subsequent withdrawal of waterlogging condition (39–45 DAE) was regarded as a recovery phase. Based on… More >

Abstract This study was undertaken to investigate oxidative stress tolerant mechanisms in chilli (Capsicum annuum L.) under drought genotypes through evaluating morphological, physiological, biochemical and stomatal parameters. Twenty genotypes were evaluated for their genetic potential to drought stress tolerant at seedling stage. Thirty days old seedlings were exposed to drought stress induced by stop watering for the following 10 days and rewatering for the following one week as recovery. Based on their survival performance, two tolerant genotypes viz. BD-10906 and BD-109012 and two susceptible genotypes viz. BD-10902 and RT-20 were selected for studying the oxidative stress tolerance… More >

Abstract The phenotypic variation and its distribution among species, morphotypes, and among and within populations was estimated in 71 populations pertaining to 15 morphotypes of three domesticated species of Capsicum from Mexico. Collections were made in the states of Sinaloa, Nayarit, Oaxaca, Tabasco, and Yucatán in two agroecosystems: Backyard-garden and monoculture. Fifteen phenotypic characteristics were analyzed through one-way variance analysis and multivariate analyses of principal components analysis (PCA) and hierarchical clustering using Ward’s method. The study was performed in a uniform greenhouse experiment. A high variation was found among and within populations in all the measured characteristics.… More >

Abstract Hot pepper (Capsicum annuum L.) is an important crop all over the world. To explore and identify differentially expressed proteins of hot pepper after space flight, three space-induced mutants (Y1, Y2 and Y3), which obtained new traits after space flight compared with their control lines (W1 and W2), were analyzed using comparative proteome analysis. In this study, leaf morphological characteristics of five kinds of hot pepper variations were evaluated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Results showed that obvious changes of cellular structure were seen in space induced mutants. Thirty nine out More >
