High pressure processing (HPP) is a novel technology that involves subjecting foods to high hydrostatic pressures of the order of 100–600 MPa. This technology has been proven successful for inactivation of numerous microorganisms, spores and enzymes in foods, leading to increased shelf life.

Hot water seed treatment is a cheap and effective way to penetrate the seed and kill pathogens that might be present.
How can I improve the germination of my seeds?
The treatment can be conducted on both sides: by a planting material producer (as a boost to regular seeds) or by a farmer (to ensure fast and effective germination and further growth).
What are the benefits of using a seed protection system?
Protects germinating seeds and seedlings against soil and seed borne pathogens/insects. Seed germination enhancement. Enhances nodulation in legume crop.
How does pressure affect germination?
Research conducted a few years ago indicated that subjecting seeds and plants to frequent changes in atmospheric pressure may shorten germination time, improve the rate of growth of young plants, and cause more massive and rapid root growth.
Which pressure for germination of seeds?
An increase in percentage germination is obtained with seeds of Medicago sativa exposed for 1 to 10 minutes at 2000 atmospheres hydraulic pressure at 20 degrees C., dried, and germinated after 30 days; and from seeds of Melilotus alba under the same conditions of pressure, when exposed for 5 to 30 minutes, dried, and ...
What is acid treatment for seeds?
7.2 Acid scarification. Soaking in concentrated sulphuric acid is the most common method of treating acacia seeds. The effect on the seed coat is similar to that of prolonged boiling and the seed coat is left dull and shallowly pitted. It is a more effective method than boiling water for many African acacias.
What is seed treatment for germination?
Seed treatment refers to the application of fungicide, insecticide, or a combination of both, to seeds so as to disinfect and disinfect them from seed-borne or soil-borne pathogenic organisms and storage insects. It also refers to the subjecting of seeds to solar energy exposure, immersion in conditioned water, etc.
Can plants grow in high pressure?
Some plants are adapted to grow under relatively high atmospheric pressure (near sea level), and others under lower atmospheric pressure (like on mountain tops). The main reason why pressure changes can affect plant growth is because it will alter the rate of gas exchange between this plant and the air.
What is plasma treatment of seed?
The seeds and seedlings can be treated directly with the plasma or indirectly at a distance away from the plasma. They can also be soaked or watered using liquids exposed to plasma. These liquids are considered as plasma-activated media (PAM) and if water is used, it is called plasma-activated water (PAW).
What is hot water seed treatment?
It is an old-age practice based on treatment with hot water whose temperature is high enough to kill the pathogen but not high enough to harm the seed, hence a very good technique to control many seed-borne diseases [12, 13].
What is the role of gibberellic acid in seed germination?
GA stimulates the seed germination whereas, ABA is involved in the establishment and maintenance of dormancy. GA exerts its influence in two manners, first by increasing the growth potential of embryo and second by inducing hydrolytic enzymes.
How is gibberellic acid used in seed germination?
In short, you fold up a small piece of paper towel, place the seeds in it, along with a pinch of GA3, and add a few drops of water. Let sit for 24 hours in a plastic baggie. Then treat as normal for germination.
What are types of seed treatment?
The treatment of seeds can be carried out in 3 different methods; Seed dressing, Seed coating and Seed pelleting.
Which treatment produces the highest germination rate?
Highest Germination percentage was observed in mechanically scarified seeds (94%) and lowest in control seeds (56%).
What is the seed treatment procedure?
Seed treatment is a term that describes both products and processes. Processes range from basic dressing to coating and pelleting. In all cases, the basis of good application techniques is to deliver the product to the seed at the correct dose and as uniformly as possible from seed to seed.
What is seed treatment?
Seed treatment is a term that describes both products and processes. Seed treatment can be done in one of the following types. Seed dressing: This is the most common method of seed treatment. The seed is dressed with either a dry formulation or wet treated with a slurry or liquid formulation.
What are the benefits of seed treatment?
Advantages of seed treatment 1 Protects germinating seeds and seedlings against soil and seed borne pathogens/insects. 2 Seed germination enhancement. 3 Early and uniform establishment and growth 4 Enhances nodulation in legume crop. 5 Better than soil and foliar application. 6 Uniform crop stand, even in adverse conditions (less/high moisture)
Can you use earthen pots for pesticides?
Dressings can be applied at both farm and industries. Low cost earthen pots can be used for mixing pesticides with seed or seed can be spread on a polythene sheet and required quantity of chemical can be sprinkled on seed lot and mixed mechanically by the farmers.
What is hot water seed treatment?
Hot water seed treatment is a cheap and effective way to penetrate the seed and kill pathogens that might be present. Not all pathogens can penetrate and survive within the seed but bacterial pathogens are commonly seed-borne, while some fungi (e.g. Alternaria leaf spot of brasscias), oomycetes (e.g. some downy mildews), and many viruses (e.g.
Why is hot water used for seed?
Hot water seed treatment is a cheap and effective way to penetrate the seed and kill pathogens that might be present.
How long does it take to treat a seed?
The temperature of water for treating seed varies from 115 to 125°F, depending on the crop, and the treatment period varies from 10 to 60 minutes. It is important to use the appropriate protocol for each crop to control pathogens without damaging the seed.
Can you heat up peas?
Large seeded crops (beans, cucurbits, peas, etc.) cannot be effectively disinfested with hot water treatment because the temperature required to heat the whole seed inside and out would kill the outer seed tissue and the seed will not germinate. To decide whether to use heat treatment, first determine the likelihood that seed-borne pathogens could ...
Can disease spread from seed?
Some pathogens can occur on or within seed and can be responsible for spreading diseases or introducing them to areas where they had not previously occurred. Even when only a small percentage of seeds are infested, disease can spread among transplants in the greenhouse or in the field, causing significant crop loss or increasing the need for sprays. In some cases, , whole seedlots may be infested and this can result in severe disease outbreaks, as all seedlings will be affected and young plants may not be able to overcome early, systemic infections. Using disease-free seed is an important first step in management of many diseases, especially for small-seeded crops where seed-borne diseases are common such as tomatoes, peppers, spinach, onions, carrots, and all the brassicas. Hot water seed treatment is a cheap and effective way to penetrate the seed and kill pathogens that might be present.
Can you use hot water for tomato seeds?
Tomato, pepper and brassicas are good candidates for hot water seed treatment because there are common bacterial diseases of these small seeded crops (eg. bacterial leaf spot of pepper and tomato, black rot of brassicas, bacterial canker of tomato, etc.). Even though bacterial pathogens do not survive well in soil once infected crop residues have ...
