Bitter melon seed sowing requires:
Soaking seeds in clean water Different soaking times have a certain effect on bitter melon seed germination; generally, as the soaking time is extended, seed germination capacity (germination vigor and germination rate) gradually increases, reaching a maximum at 12 hours, and beyond 12 hours, germination capacity shows a downward trend.
Soaking seeds in warm water Before sowing, soak the seeds in warm water at about 55°C, let it cool naturally, then continue soaking for 12 hours. This can basically kill the pathogenic bacteria attached to the surface of bitter melon seeds and can improve the permeability of the seed coat.
Soaking seeds in gibberellin Soaking seeds in gibberellin can significantly increase the germination vigor and germination rate of bitter melon seeds, among which treatment with a concentration of 40mg/kg has a better effect.
Soaking seeds in brassinosteroid (BR) BR is a new type of plant growth regulator that can promote cell elongation and division. Experiments show that soaking seeds in BR-120 at 1:1500 dilution, the germination vigor and germination rate were both significantly higher than the control, and it had a significant promoting effect on bitter melon seed germination.
Soaking seeds in hydrogen peroxide Soaking seeds in 50% hydrogen peroxide for 3 hours, then rinsing clean with clean water, has an obvious promoting effect on seed germination; its germination vigor and germination rate increased by 24.04% and 28.1% compared with the control, and the maximum germination rate reached 97%. Hydrogen peroxide has more practical significance for seeds used in large-scale production.
High-temperature germination promotion Different temperatures have an obvious effect on bitter melon seed germination. Within the temperature range of 25-35°C, as the temperature rises, both germination vigor and germination rate increase obviously; within the temperature range of 33-35°C, the germination vigor and germination rate are higher, the speed is faster, and germination is more uniform.
Mechanical scarification The commonly used mechanical scarification method is to pinch the seed coat until it cracks with pliers (tweezers), and peel it open to expose the radicle. After cracking the shell, the most suitable temperature for germination is 33-35°C.
