Testing the germination percentage or germination rate of onion seeds is an important process for determining the viability of seeds, this article provides information about onion seed germination testing methods in a lab and … Read more
The seed vigour test indicates the ability of seeds to emerge in varying environments of the field. It is generally believed, but not always true, that high germination percentage is associated with high vigour. Significant differences can be seen in the crop stand raised from different seed lots having similar germination percentages. For example, Lot … Read more
Seed Viability Tetrazolium Test: The topographic tetrazolium test was developed by Lakon (1942) in Germany. It is a quick, easy, and popular method of testing Seed viability, and requires to be known within a day or two, certain chemicals such as 2, 3, 5 – triphenyl tetrazolium chloride (TZ) or bromide, in the presence of … Read more
Seed quality: Quality seed is genetically pure, characterized by a high germination percentage and appropriate moisture content; it is free from diseases, and has a high content of pure seeds and no weed seeds. Why Does Seed Quality Matter? Seed quality is a key to achieving a uniform crop stand. Seed quality contributes to sustainable … Read more
Ultra-Dry Seed Storage Zeolite vs. Silica Gel Choosing the Right Desiccant for Seed Storage: Seed drying refers to reducing seed moisture to a safer level. It is basically done for the purpose of sustaining seed viability and longevity by minimizing attacks by storage pests and pathogens. Ultra-dry seed storage Ultra-dry storage, also known as low … Read more
A Closer Look at Different Classes of Seeds: A seed is defined as a “fertilized mature ovule consisting of an embryo, protective coat, and stored material”. Seed is any material used for planting like seeds, vegetative elements such as bulbs, cuttings, grafts of any sort, corms, tubers, rhizomes, setts, and tubers. Most of the agronomic requirements for … Read more
Seed storage is to minimize the loss of viability and vigor of seeds. Many seeds lose viability within days e.g., Cocaine (Erythroxylum coca Lamk,) and cinnamon in about 30 days and some lose in years e.g., Indian lotus, in 237 years and Silk tree (Albizia julibrissin Durazz) in 147 years. The loss in vigor is … Read more
List of Seed borne Diseases: When a pathogen is carried in, on, or with the seed, it is known as a seed-borne pathogen. And the disease caused by it is a seed-born disease. Depending upon the mode of primary initiation of the infection, the plant diseases are divided into Under the term seed-borne, normally all … Read more
The definition of Seed pelleting is a precision planting technique, that involves enveloping a seed with a small amount of inert material, forming a globular unit of standard size, making it easier to plant with precision. The objective of seed pelleting STEPS IN SEED PELLETING The three basic steps involved in seed pelleting are stated … Read more
Definition of seed dormancy “The inability of viable seed to germinate even under optimal conditions provided for germination is called Dormancy“. In general definition: Seeds of many plant species do not germinate when freshly harvested even under favorable conditions, they need a period of rest or storage before they become capable of germination. SEED DORMANCY … Read more
