Knowing our onions – experiments aid understanding of ethylene effects


Figure 1
Onion, Allium cepa, is an important cash crop, generally sold as dormant bulbs. When dormancy is broken, the leaves around the shoot apex start to elongate and the bulb ‘sprouts’. It is commercially important to inhibit sprouting and ethylene has been used for this purpose. However, as discussed by Gebhard Bufler (Stuttgart; pp. 23–28), the reported effects of ethylene on sprouting are somewhat variable, depending on onion genotype, storage temperature and time of application. The author used a cultivar, ‘Copra’, which is dormant for several weeks after harvest. Bulbs were stored at 18 °C; sprouting, as indicated by leaf-blade elongation, started after 6 weeks of storage. Sprouting was accompanied by an increase in the activity of sucrose synthase (involved in sucrose mobilization) and in ATP content. Sprouting was almost completely . . . [Full Text of this Article]
