Salinity effects on seed germination and plant growth of guar
The potential of guar [Cyamopsis tetragonoloba (L.) Taub.] as a feasible crop for saline soils was tested in this study by evaluating seed germination of 42 accessions of guar in sodium chloride (NaCl) solution. The seeds were germinated in 200 mM NaCl or double-distilled water (control). There were significant differences in salt tolerance among the accessions tested. Percentages of seeds ...

Gibberellic Acid 90 MHz - Case Study
Gibberellic acid Gibberellic acid is a plant hormone and the most used substance from the group of Gibberellins. In the industry it is used mainly to stimulate rapid stem and root growth and to speed up the germination. Figure 1 shows the 1H NMR spectrum of a 250 mM Gibberellic acid sample in MeOH-d4 measured in a single scan taking 10 seconds to ...

Salinity effects on seed germination and vegetative growth of greens-type poa annua relative to other cool-season turfgrass species
Seed germination and vegetative growth studies were conducted to determine relative salinity tolerance of greens-type Poa annua L. compared with other cool-season turfgrass species. Effects of increasing salinity stress on final germination percentage (FGP), germination rate (GR), clipping yield dry weight (CYD), verdure dry weight (VD), root dry weight (RD), and the longest root length (LRL) ...

Germination and early plant development of ten plant species exposed to TiO2 and CeO2 nanoparticles
Ten agronomic plant species were exposed to different concentrations of nano titanium dioxide (nTiO2) or nano cerium oxide (nCeO2) (0, 250 µg/mL, 500 µg/mL and 1000 µg/mL) to examine potential effects on germination and early seedling development. We modified a standard test protocol developed for soluble chemicals (OPPTS 850.4200) to determine if such an approach might be useful for screening ...

Evaluation of anaerobic digestate as a substrate for vermicomposting
Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting ...

Phenotypic and genomic responses to titanium dioxide and cerium oxide nanoparticles in Arabidopsis germinants
The effects of exposure to nanoparticles of titanium dioxide (nano‐titanium) and cerium oxide (nano‐cerium) on gene expression and growth in Arabidopsis thaliana germinants were studied using microarrays and quantitative real‐time polymerase chain reaction (qPCR), and by evaluating germinant phenotypic plasticity. Exposure to 12 days of either nano‐titania or nano‐ceria altered the regulation ...

Priming of prosopis cineraria (L.) druce and acacia tortilis (forssk) seeds with fulvic acid extracted from compost to improve germination and seedlin
Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated with ...

Nadph oxidases nox-1 and nox-2 require the regulatory subunit nor-1 to control cell differentiation and growth in neurospora crassa
We have proposed that reactive oxygen species (ROS) play essential roles in cell differentiation. Enzymes belonging to the NADPH oxidase (NOX) family produce superoxide in a regulated manner. We have identified three distinct NOX subfamilies in the fungal kingdom and have shown that NoxA is required for sexual cell differentiation in Aspergillus nidulans. Here we show that Neurospora crassa NOX-1 ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

How seed-placed fertilizer may hurt your crops if not applied carefully and attentively
Placing fertilizer within the seed row has been long-standing practice for many farmers across the prairies. Having those nutrients close to the seed makes it easily accessible by the plant, and can help the crop out of the ground and into the sun. Potash fertilizers and other nutrients, such as phosphate, are immobile fertilizers, meaning they don’t travel more than a half-inch through ...

Application of soil sensor for agriculture
Background: A moisture sensor that measures the current moisture content of the soil. Sensors into irrigation sensors help to help to facilitate more efficient distribution of water supplies. According to technical classification, soil sensors are divided into the following categories: Ground – installed below the ground to monitor the root zone; Aerial – Using drones to detect data, ...

What is the right light intensity and illumination length?
Photoperiodism The photoperiod, this is used as a signal for the plant to flower. Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochromeor cryptochrome, to sense seasonal changes in night length, The Phytochrome conversion (Pfr to Pr) allows the plant to sense when it is night or day. Phytochrome Conversion The biologically-inactive form of ...

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 ...

Sustainable Soil Health
“A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing population of the world. However, ...

Managing fertilizer’s salt effect in drought
During drought or dry conditions, salinity and pH levels can change quickly in the soil. While the forecast shouldn’t entirely dictate how you manage your farm, understanding and performing the best farming practices when adding seed-placed nutrients can help save your yields when the rain fails to ...

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. ...
