摘 要 ：本项试验研究,找出了有效储藏坡垒(Hopea hainanensis)种子的主要技术条件,这就是确定和保持种子安全含水量,大粒种子为36—38%,小粒种子为33—35%;控制储藏温度在15—20℃;降低储藏容器中空气含氧量至10—15%,以维持种子呼吸强度在CO₂40—60微升/克·时。提出了调节控制种子水份,缓慢通气,避免种子发芽、发酵和发霉的管理措施。测定了种子主要化学组成、储藏过程中种子与介质的水份变化、种子活力变化、种子呼吸强度变化和胚轴过氧化氢酶或脱氧酶活性的变化。经检验性试验证明,选用结实大年高质量种子,控制其含水量在36—38%,储藏温度18℃左右,经一年储藏后,仍保存发芽率80%以上。

Abstract:These experiments found out the principal conditions for effectively storing Hopea hainanensis seeds, which are, as the key, the dermination and maintaining of seed water content within safe ranges, 33—35% for smaller ones, 36—38% for bigger ones, the lower storage temperature at 15—20℃, and the slow ventilation resulting the air O₂ content within 10—15%. It was suggested that the measures assure these storage conditions from experiments. The chief chemical composition of kernels, the changes of seed and medium water content, seed vigor, seed respiration, and catalase or dehydrogenase activity in hypocotyls, during storage period were determinate. The experiment of test had proved that controlling seed water content within 35—38%, storage temperature at about 18℃, the high quality seeds still remained GP above 80% after storing more than a year.
