How can the germination rate of pepper seeds be improved? How should pepper seeds be treated before sprouting? We also ask knowledgeable readers to help share methodsImproving the germination rate of pepper seeds has always been a technique of concern in cultivation, so Zhongdi Network has compiled methods for improving the germination rate of pepper seeds and methods for disinfecting pepper seeds. The steps are listed in detail below for readers' reference.
Step 1: Soak the pepper seeds first, then heat-treat them:
Pepper seeds should preferably be soaked first and then heat-treated for disinfection, because heat-treating dry pepper seeds directly for sterilization causes a small portion of blighted seeds and old seeds, due to their low vigor, to easily die under intense high temperature and lose their germination ability. Soaking first allows these seeds to swell in the water and gain increased resistance, thereby improving the germination rate.
Step 2: The amount of water used for soaking pepper seeds:
For soaking pepper seeds, generally it is enough for the water to just submerge the seeds. Do not add too much water, so as not to dilute the nutrients inside the seeds and affect the germination rate of the pepper seeds.
Step 3: The water temperature for soaking pepper seeds:
To improve the germination rate of pepper seeds, the soaking water temperature should be kept at around 30°C. This allows the pepper seeds to quickly enter the suitable-temperature stage with growth vigor and enhances the sprouting ability of the pepper seeds. To maintain the water temperature, the seeds can be soaked with insulation in an incubator or cotton quilt.
Step 4: The soaking time for pepper seeds:
Through experiments, Zhongdi Network found that when pepper seeds are soaked for a long time, the sprouting time is prolonged; the sprouts produced by this prolongation grow weakly, the seedling emergence rate is low, and disease resistance during the seedling stage is also poor. It is best to keep the water temperature at 30°C and the soaking time at 2 to 4 hours (h).
Step 5: Methods for disinfecting pepper seeds:
In order for pepper seeds to sprout more, as long as the seedbed soil is properly disinfected and treated, after the seeds are sterilized with hot water at high temperature, chemical sterilization treatment may be omitted. However, after the seedlings emerge uniformly, immediately spray chlorothalonil at 600 times or copper-ammonium mixture at 400 times to control seedling-stage diseases. To stimulate pepper seed germination, soak the seeds in cytokinin at 200 times.
Step 6: Method for disinfecting pepper seeds with hot water:
Heat-treating seeds with hot water uses the high thermal energy of water to kill pathogens on the surface of pepper seeds and lurking inside the seeds. It is also a necessary means of breaking pepper seed dormancy and increasing pepper seed vigor. During heat treatment, the water temperature should be strictly controlled between 55-58°C, and the duration should last 20 minutes. Only in this way can the goal of killing pathogens without harming the seeds be achieved.
To maintain the water temperature, add hot water when the water temperature is low to keep the water temperature. To make the seeds heated evenly, stir the seeds continuously. If the amount of pepper seeds is small, the heat treatment can be done in a thermos bottle. Rinse the heat-treated pepper seeds with clean water, let the moisture dry, and then they can be sprouted.
Step 7: Methods for sprouting pepper seeds:
Wrap the soaked pepper seeds in cloth and place them in a place at around 30°C to sprout; the heat energy of an electric light can be used. If the amount of pepper seeds is small, wrap them in cloth, put them in a clean plastic bag, and place the bag inside a close-fitting shirt to use the human body's constant temperature for sprouting. During sprouting, turn the seeds frequently, soak and wash them with warm water once a day, and after washing shake off the water before continuing to sprout. According to the above methods, generally after 2 days the sprouts can all emerge, with very good results.
