種子庫收集種子保存時,適時採集和適度脫水才能有效地延長種子的貯藏壽命。With the acceleration of extinction of species, biodiversity conservation is extensively concerned. the extinction of species is concerned with the degree of threat by biotic and abiotic factors. so, taking action to preserve plant species is very necessary and paramount before their extinction. one of the most effective biological techniques to conserve the biodiversity is the establishment of genebanks, i. e. ex situ conservation. the elucidation of various factors that regulate seed viability and vigor in storage is essential. an ideal condition to prolong the longevity is mainly depended on seed water content, temperature, humidity and types of containers used during storage. the optimum stage of seed maturity, harvesting techniques and processing, in addition to physiological features such as degree of dormancy, also play key roles in seed storage. certainly, desiccated seeds deteriorate with time even under extremely good genebanking conditions. according to seed storage behavior, it is necessary to consider three principal factors : storage environment, storage duration and plant species which will affect seed survival under good genebanking conditions. the present review is an attempt to discuss the importance of the aforementioned aspects of seeds in detail in order to conserve plant germplasms ( especially wild rare and endangered plants ) for ex situ conservation through seed - gene bank
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Mass spectroscopy study of residual gases in vacuum electronic devices and its storage lifetime
