RESULTS AND DISCUSSION
The EFI of both NaCl solutions was significantly higher than the €FI of bud
pollination (Table 3.1 ). The NaCl treatments produced approximately equal €FI values.
The CI of both NaCl treatrnents and the bud pollination treatment did not differ
significantly (Table 3.1). All treatments promoted a similar level of self-oornpatibility.
The El of both NaCl treatments was not significantly different from the bud
pol lination treatment (Table 3.1 ). Approximately equal nurnbers of plants were required
to produce the same amount of seed when using bud pollination or NaCl solution
treatments.
All treatments overcame self-incornpatibility and promoted self-pollination to a
similar degree. The NaCl solution treatments were efficient, producing more seed with
less time (EFI). Bud pollination is a time consuming, labour intensive process that is
not any more effective at achieving seed set than NaCl solution treatments. This study
