Sweet potato is a cross-pollination crop, self-fertile, and the offspring propagated by seeds have very inconsistent traits and low yields.
Therefore, in addition to hybrid breeding, asexual reproduction such as tubers, stems, and potato tips is used in production.
The application of plant growth regulators such as gibberellins can break the dormancy of sweet potato seed potatoes and promote the germination of seed potatoes.
1. Gibberellins
For sweet potatoes, gibberellins also have the effect of breaking the dormancy of seed potatoes and promoting germination. When using, wash the sweet potatoes with clean water, soak them in 10~15mg/L gibberellin solution for 10min, then take them out and put them on the bed after the medicine is dry, which can break the dormancy of seed potatoes and promote germination.
2. Triacontanol
When using triacontanol to treat sweet potato tubers, soak them in 1.0mg/L solution for 10min before putting the sweet potatoes on the bed, which can promote the rooting of seed animals and early emergence.
