在室温8—10℃、相对湿度接近100%、80%N_2O+20%O_2或100%N_2O条件下贮藏荔枝和龙眼种子。研究结果表明,麻醉剂(N_2O)和氧气的混合使用可以延长荔枝和龙眼种子的寿命。而贮存在100%N_2O和空气中的种子一样会失去萌芽率。在80%N_2O和20%O_2条件下,12周以后荔枝种子仍能保持92%的萌芽率,在空气中只有44%的萌芽率。龙眼种子放在空气中,7周以后就失去萌芽率,而放在80%N_2O和20%O_2的混合气体中,可保持70%的萌芽率。麻醉剂N_2O和O_2的混合使用,能为我们提供一种贮存“顽拗型”种子的最新方法。
Litchi and longan seeds were stored at room temperature of 8-10 ℃ and relative humidity of nearly 100% with 80% N_2O + 20% O_2 or 100% N_2O. The results show that the mixed use of anesthetic agent (N 2 O) and oxygen can prolong the litchi and longan seed life. Stored in 100% N2O and seeds in the air will lose germination rate. Under the conditions of 80% N2O and 20% O2, the seeds of litchi still maintained a germination rate of 92% after 12 weeks and only 44% of the germination rate in the air. Longan seeds in the air, after 7 weeks, the germination rate is lost, and placed in a mixture of 80% N_2O and 20% O2, to maintain the germination rate of 70%. The mixed use of N_2O and O_2 anesthetics provides us with the latest method of storing “recalcitrant” seeds.
