Mountain apricot is a variant of Rosaceae, Apricot, and apricot. It is light, cold-resistant, drought-tolerant, and barren-resistant. It is a deep-rooted, strong-positive tree species with strong sprouting ability and rapid growth. It is very suitable for the growth of sunny slopes in the vast mountains of northern China. Pioneer tree species for afforestation and soil and water conservation in barren hills. At the same time, apricot also has a high economic value. The apricot kernel can be used for processing food, beverage, oil extraction, etc. Generally, wild apricot forest produces about 20 kg of apricot kernel per 667 mu per year, and artificial cultivation of apricot forest yields 667 mu per mu. The apricot kernel 50kg or more, according to the market price of 4.00 yuan / kg, the income per 667mu can reach 200 yuan / year, so it is deeply loved by the majority of forest farmers, especially in recent years with the implementation of the rural five wilderness auction and returning farmland to forest project Mountain apricots have become the main tree species in rural afforestation. The seedlings for the seedlings of the mountain apricot have also received widespread attention from many nursery units and farmers.

The ripe apricot seeds are usually yellowish-brown on the outside. After opening, the seed kernels are full and unfolded. The color is fresh and the cotyledons are milky white. The seed-bearing rate of the seed can reach more than 35%, while the picking and picking of mountain apricot seeds is white or Yellow-white, after opening, the seed is relatively flat, with more folds, and the rate of the kernel is usually below 30%. The drying and storage of the mildewy seeds can be found after the splitting, green or black mycelium can be found, and the cotyledons are yellow. White, yellow, and even individual kernels are black.
The 1000-grain weight of seed differs depending on the variety and growth environment. The lowest is below 400g, commonly known as pearl nucleus, and the larger apricot kernel can weigh more than 1200g. The clarity analysis of seeds needs to rely on related instruments, such as seed hair dryers. This instrument can perform a clean degree analysis on the seed of mountain apricots, and then put the seeds analyzed by the seed hair dryer on the seed cleanness workbench for further analysis. Careful observation and deletion.
Since the seed of Apricot apricot has a long dormancy period, it cannot be tested for its ability to germinate through a germination test. However, its vitality can be measured by a staining method. The results are similar to those measured by a germination test.
The specific method is: using chemical reagent 2,3,5-triphenyl chlorinated (or brominated) tetrazolium to prepare 0.5% ~ 1.0% tetrazolium solution, the apricot nucleus split open almonds with warm water immersion 18h, remove seed coat Re-immersed in water for more than 5 hours, and then removed and placed into the configuration of the tetrazolium solution, the dark place to keep the temperature of 30 ~ 35 °C bubble 3 ~ 4h, remove and rinse with water, and then the cotyledons to expand the observed staining, if the embryo, embryo or Most of the radicle and embryo stem or the middle part of the embryo is not identified as a nonviable seed. If only the tip of the radicle or the top part of the 1/3 cotyledon is not stained, the rest are stained. Vital seeds. It is generally required that more than 80% of the apricot seeds have vitality.
