用于预测种子在储存中的寿命的公式已经得到改进，现在它们考虑到了初始种子质量在一个物种内的变化，这受到基因型和储存前环境的影响，因此它们在更广泛的储存环境中更准确。这些改进已被纳入大麦(H.distichum L.)种子活力诺模图。其可用于预测在-20至90度范围内的任何储存环境中的任何时间之后的任何种子批次的生活力百分比。C和5-25%的水分含量。讨论了改进的方程在种子干燥和种子长期保存遗传保护中的应用。
Equations for predicting seed longevity in storage have been improved so that they now take into account variations within a species in initial seed quality, which is affected by genotype and prestorage environment, and so that they are more accurate over a wider range of storage environments. These improvements have been incorporated into a seed viability nomograph for barley (H. distichum L.) which may be used to predict percentage viability of any seed lot after any time in any storage environment within the range -20 to 90.degree. C and 5-25% moisture content. Applications of the improved equations to seed drying and to long-term seed storage for genetic conservation are discussed.
