Rapid determination of seed germination rate

Seed germination rate refers to the percentage of seed germinating in the specified number of days under the most suitable conditions. It is the main basis for determining the quality of seeds. The germination rate measured by the direct germination method takes a long time, and it is impossible to predict whether the seed is in a dormant state. A quick and practical method to determine the germination rate of seeds is now introduced - red ink staining. 1. Soak the seeds to be tested with warm water (30-35°C) for 6-8 hours to fully inflate the seeds. 2. Take 100 seeds of the swollen seeds. If they are soybean seeds, carefully remove the seed coat with tweezers; for example, the wheat corn kernels are cut in half along the midline of the embryo using a razor blade, half of which is used for measurement. 3. Place the prepared half seeds in a cup and add a 20-fold dilution of the red ink solution to immerse the seeds for the degree. 4. After 15-20 minutes of staining, pour out the solution and rinse the seeds repeatedly with tap water until the dyed color is no longer washed out. 5. Observe the coloration of the embryos in the washed seeds. The embryos are not colored or light red. That means the seeds have vitality. If the embryos are dyed in the same dark red color as the endosperm, they are dead seeds. 6. Calculate the percentage of live seeds according to the following formula. Percentage of seeds not colored in the embryo Percentage of live seeds = —————————— X100% Total number of test seeds

Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
