The quality of pepper seeds is closely related to the yield. Only after sowing, the seedlings emerge quickly, evenly, with high purity and strong growth can the quality and yield of pepper be guaranteed. Therefore, it is very necessary to distinguish the quality of pepper seeds accurately when selecting them. To distinguish the advantages and disadvantages of pepper varieties, we should start from the following aspects: (1) Pepper seeds with excellent purity cannot be mixed with seeds of other strains.

Generally, the purity of grade A seeds is not less than 98%, and the purity of grade B seeds is not less than 96%. (2) Cleanliness means that there are no inclusions or other seeds and weed seeds. Inclusions in Grade A seeds shall not exceed 2%, and other seeds and weed seeds shall not be mixed. The inclusion in Class B seeds shall not exceed' 3%, other seeds mixed in each kilogram of seeds shall not exceed 100, and weed seeds (but not quarantine objects) shall not exceed 100.

(3) Abundance Abundance is expressed by 1000-grain weight. The greater the 1000-grain weight, the fuller the seeds. The normal 1000-grain weight of pepper seeds is 4. 5? 7。 5 grams, seeds below 5 grams cannot be collected. (4) The germination rate of first-class seeds should reach 90%? 98%; The requirement for class B seeds is about 85%.

(5) Germination potential Germination potential refers to the germination rate of seeds within a specified time, indicating the degree of seed viability. 3 After the pepper is sown? After 5 days, the germination rate of seeds is higher than 85%, and the longer the germination period, the lower the output value of late germinated seeds. (6) Pepper seeds with excellent water content should keep low water content, generally around 10%.

When the water content is 14%, it is not conducive to preservation, and it will reduce the germination rate in serious cases. (7) The color seeds are bright yellow, shiny and have no musty smell.
