Abstract

The effect of ABA on reserve accumulation in maturing somatic embryos of tea was compared with and without ABA treatment. Changes in the levels of starch, total soluble sugars (TSS), proteins, and phenols were studied in the somatic embryos at different stages of development (globular, heart, torpedo and germinating embryos) in order to investigate whether ABA could trigger accumulation of storage reserves and thereby overcome the problem of poor germination. After ABA treatment (5.0 mg l-1) for 14 days, the starch and protein contents that were negligible in the untreated embryos increased by several fold with a simultaneous increase in TSS. When ABA treatment occurred at the heart stage, the germination of the embryos also improved, relative to untreated controls, after ABA treatment. ABA treatment prior to or after heart stage did not improve somatic embryo germination. & 2004 Elsevier GmbH. All rights reserved.
