Anatomical analysis of the sugar-beet seed ball indicates two possible ways for the entrance of water and oxygen during germination: cells from the operculum periphery and cells from the basal pore characterized by absence of lignin and a thin layer

Among different populations of monogerm sugarbeet fruits, those characterized by the lowest percentages of germination exhibited the lowest percentages of mechanical deoperculation (removal of the fruit cap under the sole imbitition pressure). X-ray

In vitro vegetative multiplication of sugarbeet was obtained by culturing of inflorescence explants. Subapical segments or 5-mm-long tips from nine varieties developed axillary shoots (up to 50 per tip) on a medium containing indolebutyric acid (IBA)

Rapid development of axillary buds from shoot-tips and nodes of 18 cultivars of Fuchsia hybrida was obtained on solid Murashige and Skoog medium with BAP (1 mg l−1 and an auxin (0.1 mg l−1). NAA as the auxin appeared to be more active than IAA or

Removing the operculum or placing dormant sugarbeet fruits with the operculum downward on watered filter paper resulted in an increase in germination. The importance of the operculum position was reduced under optimal watering conditions for germinat
