Photosynthesis in Plants: Holly
Holly has been traditionally used as a Christmas decoration in many western countries. Being an evergreen plant, holly carries out photosynthesis throughout the year. In the cold winter months its leaves adapt to the lower temperatures by reducing their yield of photosynthesis. Interestingly the efficiency of photosynthesis follows an opposite trend to the quantum yield of fluorescence from ...

McCree – photosynthetic active radiation
Institute of Life Science and Biology Department, Texas A and M University, College Station, Texas U.S.A. Spectral quantum yields The aim of these measurements is to provide a factual basis for a standard definition o f “photosynthetically active radiation”. The need for a standard definition has been repeatedly emphasized (e.g., GABRIELSEN, 1940; RABINOWlTCH, 1951, ...

Maximize Yields with Smart Lighting Strategies: Using Metrics for a More Efficient Grow
There is a strong relationship between lighting and yield, as we know that with every 1% increase in light, there is a 1% increase in growth and yield. Measuring yield in your greenhouse is an important way to measure efficiencies and profitability, so you can better assess how your inputs affect overall yield and plant growth. In this article, we are going to overview the relationship ...

Better photosynthesis for a better world?
There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

Features of impulse sprinkling technology
The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth ...

A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis
Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...

Micronutrient research using leaf area & photosynthesis rates to improve crop yields
With the pressure to increase food production, every agricultural practice that can be optimized for improving crop yield is under scrutiny; therefore, micronutrients, which are important for crop health and growth, are receiving more attention. Agronomists are increasingly studying different treatment methods to establish the easiest and most cost-effective way to improve micronutrient ...

Illumination sensor in intelligent agriculture
Summary: With the development of intelligent agriculture in the Internet of things, many agricultural sensors appear in agricultural environmental monitoring, among which illumination sensor is a more important one.The sensor measures the intensity of light, which affects photosynthesis and, in turn, crop yields.In smart agricultural planting, the illumination sensor can detect the information of ...

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, ...

How to create resilient agriculture
Durable food security and agricultural growth depend on development strategies with resilience built in from the start, says Gordon Conway. Economic growth with resilience to environmental threats will be central to the agenda of the UN Conference on Sustainable Development (Rio+20) in June this year, which aims to map out a pathway of sustainable development for the planet. The 'zero draft', ...

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 ...
