Corn seed purity has always been a major concern for farmers and seed professionals. There are five main methods used to assess this: morphological evaluation, seedling analysis, fluorescence testing, electrophoresis, and field planting identification. Each of these techniques has its own advantages and limitations. The latter four methods often require specialized equipment, take longer to complete, or lack the speed and simplicity needed for quick assessments. Morphological analysis, on the other hand, is fast, simple, and effective—yet it can be influenced by the skill level of the person conducting the test, leading to inconsistent results. To make the most of morphological analysis and leverage its strengths, several key steps should be followed during actual operations: 1. **Understand the basis of corn grain morphological traits** Corn grain morphology includes characteristics such as grain type (horse tooth, semi-dent, flint), color (white, yellow, red, purple), top shape (rectangular, oblong, round), top color, silt amount, embryo size and shape, presence or absence of folds, the position and degree of silk remnants, pod color (white, light red, purple), and the sharpness of the grain edges. Among these, the top color is the most critical for identifying direct seedlings and sensitive reactions. 2. **Master the morphological determination process** The procedure involves the following steps: - Randomly select 400 seeds. - Divide them into four replicates, with 100 seeds per replicate. - Observe under even lighting, avoiding direct sunlight to prevent misjudgment. - Use your left index finger and thumb to hold two or three standard seeds, then compare the others using your right hand. - Distinguish in the order of F2 → grains → self-crossed grains → true seeds. 3. **Apply skilled differentiation techniques** For most farmers who may not have extensive knowledge of seeds, the first step is to observe the grain’s shape, top appearance, edge sharpness, and color. Typically, hybrid grains and F2 seeds tend to be dent or semi-dent, with long, flat, and angular shapes. Red-colored varieties include Duan Shan No. 2, Shen Dan No. 7, Dan Yu No. 13, Lu Yuan Dan No. 14, Lu Yu No. 14, and Lu Dan No. 50, among others. After that, focus on the top color, which can be categorized into deep, medium, and light. By comparing and calculating the ratios, you can estimate the purity. For seed workers, distinguishing self-crossed grains is crucial, as they cause significant yield loss. The key trait to look at is the top color, not the pericarp or embryo. This is because the pericarp develops from the ovary wall and doesn’t show direct seedling characteristics, while the embryo, though fertilized, is too small and covered in an opaque layer. The grain color reflects the parent's endosperm, which can be misleading. However, the top color is more reliable, especially when only part of the grain shows sensitivity. - **Deep Type**: When the mother plant has a dark color, the hybrid’s top color tends to be deeper. Examples include Yandan No. 15, Dandan No. 12, No. 13, No. 22, No. 2 (Huang Zao 4掖107), and Xiyu No. 3. - **Shallow Type**: If the mother plant is dark but the hybrid has a lighter top, it’s considered shallow. Examples include Yidan No. 2 and No. 4, Luyu No. 10 and No. 16, and Luyuan Dan No. 14. - Some varieties, like Nongda 60, Nongda 65, Zhongdan 2, and Danyu 13, have top colors that are hard to distinguish. In such cases, comparing the parent and hybrid seeds is essential. Alongside mastering these techniques, seed workers should also become familiar with the characteristics of major maize inbred lines and practice regularly. It’s also important to cross-check with electrophoresis and field tests to improve accuracy and refine their skills over time.

8D NLS

What is Vector 8D NLS?
The purpose of this training program is not a detailed physical justification of the principles of the «8D-LRIS» device, since different devices are designed differently. Currently, there are several manufacturers of this equipment, [spinoffs" from the original research group. In particular, in the original version of Russian, the headphones were used as magneto-inductors with an oscillation frequency, which is close to the thetarhythm of the brain, while in later versions of the device - as a conductor of electromagnetic waves that are close to the alpha rhythm of the brain. A good effect is obtained from the use of electromagnetic waves as a trigger mechanism for the study of a healthy body.Also, in many other versions of the device, laser emitters are used to affect the brain of the patient.Using the laser leads to an increase of the resonant response. However, there is a risk of adverse effects of such exposure, so the laser
emitter is not used in all models of «8D-LRIS» equipment.

Facts about the program:
Equipment set up on a modern element base, has a stylish design, and interfaces with a PC via USB-port. The unit LRIS-nls device has a digital trigger sensor in the unit and an analog trigger sensor which is built into the bio inductor.

The program works steadily on any Windows operating system (Windows operating system XP/Vista/7) New versions are available for free download from the site

Base standards greatly expanded and continue to grow A detailed user E-manual is included.

Assessment of the chakras and aura.

(An aura is the electromagnetic field that surrounds every living being and is manifested in the physical field by electrically charged objects that represent themselves as different colors that surround the body. This electromagnetic field can provide information regarding a person`s emotional state, the quality of consciousness and will determine the level of health regarding an individual organ and organ systems.)

8d LRIS NLS Range:
LRIS-NLS can be used by anyone who is interested in quickly and effectively examining the health of their patients, clients, friends, family or employees. Accurate analysis is the driving factor of our company and no matter whom you are or what you do, you will be well informed with the information you will gather from the LRIS-NLS device, and so will everyone you work with.

Remember that the information is being gathered on a cellular level, and the beauty of this method of diagnosis is that before anything is manifested, it is found.

People who fall under any of the following categories are welcome, advised and will find benefit in using and having a LRIS-NLS biofeedback device.
