How to analyze photosynthesis in plants: Methods and tools
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 result, there are a plethora of methods ...

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. ...

The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

Non-Destructive Root Imaging - Webinar and Live Demo
Alright, so, we are just about a full house here already. So, we’ll get started with the presentation. As you should be able to see on your screen, it should say, “A Change of View: Using Root Imaging to Expand your Research by CID Bio-Science.” Online with me is actually our distribution manager, Suzy Truitt. She’ll be helping in the background facilitating with the Q ...

Choosing the Right Light for Young Plants
Horticulture lighting research has been conducted on young plants (germination, seedlings, plugs and cuttings) for many years. Michigan State University published a series of articles in Greenhouse Grower (see references below) on bedding plant seedlings. In their research, Drs. Wollaeger and Runkle experimented with different LED wavelengths and compared them to fluorescent light on seedling ...

Using leaf area meters: Assessing roosting sites for Melon fly and Oriental fruit fly - Case study
Assessment of Attractiveness of Plants as Roosting Sites for the Melon Fly, Bactrocera cucurbitae, and the Oriental Fruit Fly, B. dorsalis. The Researcher Dr. Grant McQuate is a researcher with the USDA Agricultural Research Service (ARS) in Hilo, Hawaii. With over 24 years of experience in research in insect ecology, Dr. McQuate has focused much of his work on the attraction, ecology, host ...

Estimation of maize evapotranspiration using extreme learning machine and generalized regression neural network on the China Loess Plateau
Accurately estimating crop evapotranspiration (ET) is essential for agricultural water management in arid and semiarid croplands. This study developed extreme learning machine (ELM) and generalized regression neural network (GRNN) models for maize ET estimation on the China Loess Plateau. Maize ET, meteorological variables, leaf area index (LAI), and plant height (hc) were continuously ...

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, ...

The ratio of transpiration to evapotranspiration in a rainfed maize field on the Loess Plateau of China
Maize (Zea mays L.) is a major crop on the Loess Plateau, and calculating the ratio of transpiration to evapotranspiration (T/ET) of maize is important for estimating field water balance. In this study, the sap flow method was adopted to measure transpiration (T) characteristics of maize. In order to calibrate the sap flow gauge, the sap flow rate was compared to the leaf T determined by the ...

Effect of recycled water applied by surface and subsurface irrigation on the growth, photosynthetic indices and nutrient content of young olive trees in central Iran
Water shortage has encouraged the quest for alternative sources of water for food production and agricultural development. Recycled water (RW) is one of the most available water resources with great potential for use in farm irrigation. This experiment was carried out to investigate the use of RW as the irrigation source and its application method, subsurface leaky irrigation (SLI) system or ...

A study on crown interception with four dominant tree species: a direct measurement
An experiment was conducted to concentrate on the rainfall interception process of individual trees for four common species in Beijing, China, which included needle species (Platycladus orientalis and Pinus tabulaeformis) and broadleaf species (Quercus variabilis and Acer truncatum). Two types of interception storages, the maximum (Cmax) and the minimum interception storage (Cmin), were ...

Ethylene removal in Pears
The Conference pear has a greenish skin with brown marks and a consistent greenish-white pulp. It is a widely grown and consumed variety in Europe. It can be stored for up to 9 months in controlled atmosphere conditions in refrigeration chambers, a period in which the effect of ethylene on the fruit can lead to a major loss of quality. Ethylene accelerates the ripening and senescence of the ...

Crop yield increased with the addition on Citadel Biocat+ in the digestate
Field applications evaluations of digestate from BioCat+ treated AD plants are under way in three locations in Europe. From initial results and observations it is apparent that the BioCat+ treated digestate has an improved symbiotic effect in the crop rhizosphere. Crops of wheat and maize recently harvested have shown increases in yields of up to 23% higher yields than previously achieved on the ...

Observations and snow model simulations of winter energy balance terms within and between different coniferous forests in southern boreal Finland
Variation of canopy properties between different forest types is seldom taken into account in hydrological and climate models, and consideration of variation inside a forest is normally omitted. In this work, three data sets on near surface energy balance terms (incoming shortwave and longwave radiation; air and snow–soil interface temperatures) were collected in the southern boreal ...

The extrapolation of the leaf area-based transpiration of two xerophytic shrubs in a revegetated desert area in the Tengger Desert, China
Plant transpiration plays a key role in sand-binding zones, but obtaining accurate estimates at an integrated leaf-individual-canopy scale is difficult. In this study, transpiration rates of two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were investigated during the growing season (April–October) from 2008 to 2012 in the Tengger Desert, a revegetated desert ...
