Figure 1. The effect of after-ripening and sense- ßGlu I transformation on testa rupture (A) and endosperm rupture (B) during the germination of tobacco seeds. Fresh (filled columns) or after- ripened (stippled columns) progeny seeds from reciprocal crosses of a homozygous monogenic sense-ßGlu I lines (TKSG7) or an empty-vector (TCIB1) line with wild-type (WT) were compared. The female parent in cross is on the left and the male parent is not shown in self crosses. The incidence of testa and endosperm rupture expressed as percentage was scored over time from the start of imbibition in continuous light and the time needed for 50% rupture was determined. Mean values presented are based on the results from three independent TKSG7 lines; mean values ± SE for each single TKSG7 line and further details are published in Leubner-Metzger (2002). |
