从健康果实中取出的荔枝种子分别放入加有0．1％代森锌的海藻酸钙溶液中，然后在2％氯化钙溶液中胶丸化，形成胶丸种子。胶丸种子和非胶丸种子在10℃下贮存80天，非胶丸种子在10℃中贮藏40天发芽率是11．7％，胶丸种子（4％海藻酸钙）在贮藏80天后仍有53．3％的发芽率。结果表明用海藻酸钙制成的胶丸可延长荔枝这样的“顽拗型”种子的贮藏寿命。
The lychee seeds taken from the healthy fruits are respectively put into calcium alginate solution with 0.1% dexmedetomidine and then shot in the 2% calcium chloride solution to form capsule seeds. Capsule seeds and non-capsule seeds were stored at 10 ° C for 80 days, non-capsule seeds stored at 10 ° C for 40 days Germination rate was 11.7%, capsule seeds (4% calcium alginate) were still stored after 80 days There are 53.3% germination rate. The results show that capsules made from calcium alginate can extend the shelf life of “recalcitrant” seeds such as litchi.
