Figure 2From: Somatic embryogenesis for mass propagation of elite Spruce families: effect of storage time on somatic embryogenesis initiationSE initiation rates from seeds from different seed batches and collection years. The SE initiation rate for each seed batch is shown in percentage of seeds tested (90 for each batch) that produced PEMs that could be isolated and cultured. Only one cell line per seed was recorded.Back to article page
