一個物種的滅絕是與其受生物因子和非生物因子的威脅程度相關的.隨著物種的加速絕滅,保護生物多樣性受到廣泛地關注.保護生物多樣性的最有效的生物技術之一是建立種子基因庫,進行遷地保護.種子庫理想的貯藏條件主要取決于種子含水量、貯藏環境(如溫度和濕度)和貯存種子的容器.進行種子貯藏,了解種子生命力和活力的影響因子的作用機理是十分重要和必要的.除了種子自身的生理特徵外,種子的貯藏壽命與種子成熟度、收獲技術、加工處理方法也是息息相關的.即使在最適的庫存條件下,種子也會隨時間發生劣變.因此,必須根據種子特定的貯藏行為,加以考慮影響種子存活的3個主要方面(貯藏環境、貯藏期和植物種類)而選擇有效的貯藏方案.本文試圖討論種子貯藏生理的幾個重要方面及其需解決的技術問題,以便更好地通過種子基因庫,長期有效地保存植物種質資源分享友人
