Soil water reserve estimation and vegetation relationships in a Mediterranean sub-humid forested catchment
A simple water balance model was used to calculate soil water reserve in a Mediterranean forested catchment. The relationship between soil water reserve and leaf water potential and stem water content was analysed. The usefulness of these variables as plant water status indicators was tested. The analyses were developed with a seven-year-long database (2001–2007) in the case of soil water content ...

Evolution of quality indices of fresh bunched spinach stored using low density polyethylene and polypropylene bags
Packaging technology constitutes an available method for reducing postharvest deteriorative processes on fresh products. The purpose of this work was to evaluate leaf water status, weight loss and colour retention of bunched spinach leaves packaged in low density polyethylene (LDPE) and polypropylene (OPP) bags, stored at 2°C for 25 days. Water status was determined through relative water content ...

Differential effects of low humidity levels on butterhead quality indices related to external, middle and internal lettuce sections
Leaf water status evolution during greenhouse butterhead lettuce storage under adverse humidity conditions was evaluated. The relationships between water status and the chlorophyll content and overall visual quality (OVQ) were analysed. Parameters were evaluated in external, middle and internal sections of the lettuce heads. Indices showed different behaviour in different sections. There was a ...

Impact of varying planting Dates and tillage systems on cotton growth and lint yield production
As economic conditions deteriorated, cotton (Gossypium hirsutum L.) producers have looked to improve profit margins by reducing inputs while maintaining yields. Pairing the yield benefits from early planting with the input reductions from conservation tillage might help accomplish those goals. The objective was to determine how growth, lint yield, and fiber quality were impacted by planting ...

Yield and water use response of cuphea to irrigation in the Northern Corn belt
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

Sprinkler irrigation changes maize canopy microclimate and crop water status, transpiration, and temperature
During a sprinkler irrigation event some water is lost due to wind drift and evaporation (WDEL). After the irrigation event, plant-intercepted water is lost due to evaporation. The water lost causes microclimatic changes which could result in positive or negative plant physiological changes. We studied the microclimatic and physiological changes on two fields grown with maize (Zea mays L.) ...

Canopy gas exchange measurements of cotton in an open system
A portable, open transparent chamber system for measuring canopy gas exchanges was developed and tested. Differentials between incoming and outgoing atmospheric H2O and CO2 concentrations were used to calculate canopy transpiration (E) and net assimilation (A) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. A programmable data logger controlled ...

What are leaves and why are they important? - Case study
As a research scientist, you’ve dedicated your life to understanding and communicating details about plants that others haven’t considered in the past. Our infographic below focuses on the leaf basics: what leaves are, what they do, and why they are so important. Share it with your students, your friends and family, or just use it as a reminder of why you do what you do. Plus, ...

Environmental fate of emamectin benzoate after tree micro injection of horse chestnut trees
Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut ...

Tree, Crop & Plant Stress – A Primer on Abiotic and Biotic Stressors
The natural conditions in which plants and trees grow are neither uniform nor controlled. Many changes or fluctuations, even if they are temporary, can have a negative impact on and stress plants. The factors which can lead to stress can be one of two types: abiotic or biotic. Stress can have serious repercussions on various phases of a plant’s growth and, ultimately, crop productivity. ...

Dairy production in Turkey Case Study
NEUTHOX® removes biofilm in cooling tower and leaves the water system completely free of unwanted bacteria Using an electrolysis process of saltwater the ECA generator produces the liquid NEUTHOX®, which contains hypochlorous acid, and is highly efficient in eliminating bacteria. A biofilm consists of living and dead organic and inorganic material collected on a surface, which in water ...

Tractor Manufacturer
The wastewater from the tractor manufacturing facility was being trucked to a wastewater treatment facility 120 miles away for treatment and disposal of the wastewater. The wastewater consists of heavy cutting oils/lubricants that could not be treated using conventional chemistries. Integrated Engineers developed a treatment process, which involved Floccin. The mixing requirement was heavy to ...

Aiming to optimize irrigation levels
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...

Mineral Oxychloride to rescue citrus market in Florida
Since 2019 over 75% of the citrus crops (oranges 75% and grapefruit 85%) has been lost due to an infectious bacterium called huanglongbing (HLB) commonly known as “citrus greening”. Leaves of newly affected trees developed blotchy mottle appearance and the fruit is of no value-it has limited use in juicing operation. As of today, there has not being a commercially available solution ...

8 Main Points of Aquatic Plant Trimming (1)
1. It is best to turn off the Surface Oil Skimmer when trimming Foreground grasses, such as cow Eleocharis parvula, Hemianthus callitrichoides 'Cuba', and Glossostigma elatinoides, have a lower density than water, and there will be a lot of debris floating on the water when trimming. The debris is likely to enter from the surface skimmer into the filter cartridge, causing excessive accumulation ...

Subsurface drip irrigation; the future of Irrigation is Underground
Placing water beneath the soil surface via buried lines is slowly becoming the "preferred choice" of many vineyard irrigators. The reasons are many, including the absence of surface evaporation, as well as reduced weed growth, herbicide washout, maintenance, injury, and vandalism found with using conventional water application systems. The advantages of subsurface drip add to reduced cost for ...

How to Analyze Photosynthesis in Plants: Methods and Tools
Photosynthesis: Why is it important? Life as we know it would be impossible without photosynthesis. Outside of providing the essential elements that support life on earth, photosynthesis is of special importance to the food and agriculture industry, as well as for ecologists studying climate change. In addition, there are many commercial enterprises which depend heavily on photosynthesis. As a ...
