Waterlogging occurs because of poor soil drainage and/or excessive rainfall and is a serious abiotic stress affecting plant growth declining oxygen supplied to submerged tissues. Although cucumber (Cucumis sativus L.) sensitive waterlogging, its ability generate adventitious roots facilitates gas diffusion increases survival when concentrations are low. To understand the physiological responses 10-day waterlogging experiment was conducted. The objective this study measure photosynthetic key...

Studies were conducted to relate the influence of physical characteristics, leaf nutrient content and phloem sap amino acid concentration citrus flush shoots on densities various Diaphorina citri life stages. Adult D. preferentially selected young for feeding numbers immatures positively correlated with shoot softness. Young had higher concentrations macro micro nutrients relative mature ones this was associated all All stages nitrogen-carbon (N:C), nitrogen:sulfur (N:S) nitrogen:calcium...

The consumption of plants plays an important role in human health. In addition to providing macro and micronutrients, are the sole sources several phytonutrients that play a major disease prevention. However, modern diets, increased cheaper, processed foods with poor nutritional value over fruits vegetables leads insufficient essential nutrients such as vitamin C. Taking supplements can address some diet. not diverse or bioavailable plants. Improving abundance will reduce amounts need be...

Urban green spaces provide many benefits, including to human wellbeing, ecosystem services, and urban wildlife. Thus, there are reasons up spaces, especially by using native species. Furthermore, suited enhancing biodiversity without negatively impacting food or fiber production. Municipalities private landowners invest substantially in landscaping its maintenance. However, much of that outlay supports non-native plants may be less adapted local conditions such as rainfall patterns...

Neonicotinoids are one of the most widely used classes insecticides in agriculture. They systemic mainly as seed treatments to manage sucking insect pests a wide range field crops. Environment and growing conditions can impact efficacy neonicotinoid treatments. To evaluate this, an experiment was conducted study interactive effect soil, water levels on concentration plant growth cotton. The laid out split-plot design, with three levels, 30%, 60%, 100% (control) recommended irrigation four...

Abstract Water deficits are among major agricultural issues in semi‐arid West Texas and require water‐saving practices like growth stage‐based irrigation management biochar. A 2‐year (2021 2022) field experiment was conducted a split‐plot design with based on crop evapotranspiration (ETc) as main plot factor four levels (I1 [100% ETc for whole growing season], I2 [80% stress at vegetative stage followed by 60% reproductive stage], I3 [60% 80% I4 [40% season]) biochar subplot three rates (0,...

Despite growing interest in adopting water-conserving strategies such as deficit irrigation (DI) and biochar amendment arid semi-arid regions, there are remarkably few studies conducted on the integration of these two water limited West Texas region. The aim this study was to assess interactive effects DI saturated hydraulic conductivity soil growth, physiology yield cucumber (Cucumis sativus) Texas. A split-plot design used randomize four treatments (with levels before after mid-season)...

Huanglongbing (HLB) and Phytophthora foot root rot are diseases that affect citrus production profitability. The symptoms physiological changes associated with these diagnosed through expensive time-consuming field measurements. Unmanned aerial vehicles (UAVs) using red/green/blue (RGB, true color) imaging, may be an economic alternative to diagnose diseases. A methodology a UAV RGB camera was developed assess health. flown in April 2018 on grapefruit infected HLB rot. Ten trees were...

Edible flowers are a rich source of phytochemicals with potential health benefits. Yet, changes in production practices can influence the phytochemical composition edible flowers. Practices such as addition biochar have been used to affect growing media properties well conserve peat resources. However, there is little known about how affects To determine if Viola cornuta, four cultivars were subjected different rates biochar, and without fertilizer. At rate 10% fertilizer application, flower...

Saline irrigation water can lead to salt buildup and reduced crop yields. Halophytic plants are known accumulate excess salts in tissues, removing them from the immediate environment. This two-phase experiment explored feasibility of intercropping watermelon (Citrullus lanatus (Thunb.) Matsum. Nakai var. lanatus) with halophytic species mitigate negative effects saline while providing a value-added crop. In first experiment, six greenhouse-grown were irrigated that was either deionized (0 dS...

Increasing costs and environmental issues regarding excessive use of peat moss is impacting the horticultural industry. Biochar a valuable substrate additive that has potential to reduce peatmoss in greenhouse production. However, its varying effects on ornamentals requires individual species cultivars crops must be evaluated determine threshold for benefits. Viola cornuta high value ornamental crop; however, information how different rates biochar affect productivity physiology container...

Passive and active interactions with nature reduce stress, anxiety, depression. Populations that experience increased stress often have fewer due to many factors. More recently, the COVID-19 pandemic has created a new stressor for all populations sickness, isolation, financial burdens, or other University students were particularly impacted change online modalities, which isolated them from students. To assess if any negative consequences experienced factors could mitigate them, we examined...

Abstract Vitamin C (Vit C) is an essential micronutrient and antioxidant for human health. Unfortunately, Vit cannot be produced in humans ingested through diet while severe deficiencies can lead to scurvy. However, consumption often inconsistent, foods vary concentrations. Biofortification, the practice of increasing or mineral concentrations, improve nutritional quality crops allow more consistent dietary levels these nutrients. Of three leading biofortification practices (i.e.,...

High temperatures and drought are common stresses limiting crop growth productivity in subtropical regions where citrus produced. In addition to impacts on physiological processes such as transpiration, photosynthesis, respiration, excessive solar radiation can also reduce fruit by inducing disorders sunburn. This study evaluated the effects of reflectants anti-transpirants leaf physiology, sunburn grapefruit trees (Citrus xparadisi Macfs. cv. Rio Red) south Texas during 2016 2017 growing...

Soilless production systems (i.e hydroponics, aeroponics, aquaponics) have become commonplace in urban settings and controlled environments. They are efficient nutrient recyclers, space savers, water conservers. However, they lack high levels of biological richness the root microbiome when compared to soil systems, which may affect plant health uptake. To address this issue incorporate more sustainable practices, beneficial microorganisms (i.e. Trichoderma spp., Bacillus sp.) can be added...

Huanglongbing is a devastating disease of citrus. In this study, comprehensive profile phloem sap amino acids (AA) in four permissive host plants Candidatus Liberibacter asiaticus (CLas) and three non-permissive Rutaceae was conducted to gain better understanding factors that may promote or suppress the bacterium. The AA profiles Diaphorina citri nymphs adults were similarly analyzed. A total 38 unique AAs detected various D. samples, with young shoots containing more at higher...
