Germination rate is the significant characteristic determining coconut palm diversity

---

Abstract.
Rationale:
This review comes at a time when in vitro embryo culture techniques are being adopted for
the safe exchange and cryo-conservation of coconut germplasm. In due course, laboratory
procedures may replace the options that exist among standard commercial nursery germination
techniques. These, in their turn, have supplanted traditional methods that are now
forgotten or misunderstood. Knowledge of all germination options should help to ensure
the safe regeneration of conserved material.

Scope:
This review outlines the many options for commercial propagation, recognizes the full
significance of one particular traditional method and suggests that the diversity of modern
cultivated coconut varieties has arisen because natural selection and domestic selection
were associated with different rates of germination and other morphologically recognizable
phenotypic characteristics. The review takes into account both the recalcitrant and the
viviparous nature of the coconut. The ripe fruits that fall but do not germinate immediately
and lose viability if dried for storage are contrasted with the bunches of fruit retained in
the crown of the palm that may, in certain circumstances, germinate to produce seedlings
high above ground level.

Significance:
Slow-germinating and quick-germinating coconuts have different patterns of distribution. The
former predominate on tropical islands and coastlines that could be reached by floating when
natural dispersal originally spread coconuts widely—but only where tides and currents were
favourable—and then only to sea-level locations. Human settlers disseminated the domestic
types even more widely—to otherwise inaccessible coastal sites not reached by floating—and
particularly to inland and upland locations on large islands and continental land masses. This
review suggests four regions where diversity has been determined by germination rates.
Although recent DNA studies support these distinctions, further analyses of genetic
markers related to fruit abscission and germination are recommended.
