Abstract Banana is a tropical crop cultivated in warm places. Chilling stress in Egypt is making banana crops less productive. Abscisic acid (ABA), a key plant hormone, regulates metabolic and physiological processes and protects plants from a variety of stresses. In vitro growing banana shoots were pre-treated with ABA at four concentrations (0, 25, 50, and 100 mM) and chilled at 5°C for 24 h, followed by a six-day recovery period at 25°C. By comparing ABA treatments to both positive and negative controls, physiological and biochemical changes were investigated. Chilling stress (5°C) caused a considerable increase in lipid peroxidation and ion… 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 their survival performance, two… 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 mechanism. Drought reduced root… More >

Abstract Low-temperature storage is extensively used to optimize the postharvest life of various fresh fruits. However, red pitahaya (Hylocereus polyrhizus) fruits are sensitive to chilling injury (CI), which leads to the limitation of low-temperature storage. In this study, red pitahaya fruits were stored at 2, 4, 6, 8, and 10°C, respectively, for 27 days to determine the appropriate storage temperature. During the storage of red pitahaya fruits, storage at 8°C was more effective in suppressing decay and maintaining quality than other low temperatures. Low-temperature (2, 4, and 6°C) storage decreased weight loss (WL) and maintained higher content of titratable acidity (TA),… More >

Abstract The purpose of this study was to investigate the effects of various presowing treatments on the germinability (final germination percentage) and germination rate of loquat seeds in order to increase seedling production in nurseries (applied research) as well as provide answers for important physiological issues related to loquat seeds and their seed coat (basic research). Three experiments were carried out with various pre-sowing treatments. These treatments included full or partial removal of seed coat (perisperm), partial cutting of cotyledons as well as moist chilling at 5°C for 13 days and/or soaking the seeds in water or 250 ppm gibberellic acid… More >

Abstract Fourteen native strains of Trichoderma spp. from wildand agricultural pathosystems in the state of Yucatan, Mexico, with growth-promoting ability of Capsicum chinense Jacq. seedlings were evaluated and antagonistic effect of their filtrate against second-stage juveniles (J2) of Meloidogyne incognita. The strains Th05-02 and Th27-08 showed the best significant effects on plant hight variable increments 55.57 and 47.62%, theTh07-04 with 29.48% more root length, theTh02-01 and Th07-04 isolates increased from 48.71 to 84.61% in volume radical and 53.40% of total dry biomass. Statistical analysis (p≤0.001) of Th43 and Th43-13-14 filtrates caused 100% mortality at 24 and 48h. In the test of… More >

Abstract A morphological characterization in situ of Capsicum spp was made in 13 localities in the state of Tabasco, México, during 2004 and 2005. The objective was to sample and identify different morphotypes of chilli pepper which grow under wild and cultivated conditions. Eleven chilli pepper morphotypes were found. Most of them were wild (Amashito, Corazón de pollo, Muela, Garbanzo, Garbanzo raro and Desconocido) and corresponded to C. annuum. Another morphotype was half wild (Picopaloma) and corresponded to C. frutescens. The remaining morphotypes corresponded to C. annuum and C. chinenese. Data were analyzed with multivariate statistics. Principal component analysis (PCA) indicated… More >

Abstract Cold storage is one of the most important technologies used to maintain the postharvest quality of many horticultural commodities. However, cold storage is restricted for Persian lime because of its susceptibility to chilling injury. The objective of this study was to evaluate the effects of high temperature conditioning on the susceptibility to chilling injury in Persian lime (Citrus latifolia Tanaka). It was harvested in Martínez de la Torre, Veracruz, Mexico, and stored at different refrigeration temperatures. After harvesting, fruits received the following treatments: (1) hot water conditioning (53 °C during 3 min); (2) hot air conditioning (38 °C, 90-95 %… More >

Abstract Chilling stress on cereal crops is the major form of cold stress that appears in some regions, and causes significant losses by depressing seed germination, and seedling growth and establishment. Hormones have the ability to reduce the stress effects in crops by various mechanisms. To determine the role of nitric oxide in mitigating chilling damages in wheat, two trials were conducted and seven wheat varieties were used. Seeds of wheat varieties after priming using three different concentrations (0, 10^-4, 10^-5 M) of sodium nitroprusside as nitric oxide donor were grown under two growth conditions (control, 4 °C) according to a… More >

Abstract Efforts to improve crop yields with efficient use of fertilizers are needed to guarantee global food security. Enhanced slow-release fertilizer systems (SRFs) encapsulated in biodegradable matrices are being developed to address this global concern. From a wide range of strategies for SRFs development, we explored a nature-inspired solution based on the plant cuticle model and its function as a membrane for water and nutrient transport control. Here, Candelilla wax, extracted from Candelilla wild plants (Euphorbia antisyphilitica), is studied as a renewable slow-release matrix for fertilizers encapsulated by a modified spray chilling process. From this process, microencapsulates containing 40 wt% of… More >
