How to deal with balsam pear seeds before sowing?

How to deal with balsam pear seeds before sowing? Please advise balsam pear seed sowing needs: different soaking time of balsam pear seeds in clear water has a certain effect on balsam pear seed germination. Generally, with the extension of soaking time, seed germination power (germination energy and germination rate) gradually increases, reaching the maximum at 12 hours, more than 12 hours, germination ability showed a downward trend. Soaking seeds in 55 ℃ warm water before sowing seeds in warm water and soaking seeds for 12 hours after natural cooling can basically burn the pathogens attached to the surface of balsam pear seeds and improve the permeability of seed coat. Soaking seeds with gibberellin could significantly improve the germination energy and germination rate of balsam pear seeds, and the effect of 40mg/kg concentration was better. Seed soaking with brassinolide (BR) BR is a new type of plant growth regulator, which can promote cell elongation and division. The results showed that the germination energy and germination rate of seed soaking with 1500 times BR-120 were significantly higher than those of the control, which could significantly promote the germination of balsam pear seeds. Soaking the seeds with 50% hydrogen peroxide for 3 hours, and then rinsing them with clean water can obviously promote the seed germination. Compared with the control, the germination energy and germination rate are increased by 24.04% and 28.1%, and the limit germination rate is up to 97%. Hydrogen peroxide is of more practical significance for large-scale production. The germination of balsam pear seeds was obviously affected by high temperature and different temperature. The germination energy and germination rate increased obviously with the increase of temperature in the temperature range of 25-35 ℃. The germination energy and germination rate were higher, faster and neat in the temperature range of 33-35 ℃. The commonly used method of mechanical injury is to crack the seed coat with pliers (tweezers) and peel it off to reveal the radicle. The optimum temperature for germination after breaking shell is 33-35 ℃. Click to get more balsam pear planting techniques click to get more vegetable planting techniques
