itiation well before 31 May (see Fig. 4.43). Such crops are likely to bolt because
scape elongation will occur before competition from bulbing begins to suppress
developing inflorescences. Small intervals between sowing dates translate into
much longer intervals between the dates at which plants reach the various stages
of inflorescence development, depending on how temperatures vary over the
autumn, winter and spring - which, of course, varies from year to year.
Fig. 4.43.
The range of dates on which a developmental model predicted that
various stages of inflorescence development would have been reached following
sowings made between 2 August and 4 September during the years 1973 to 1988 at
Wellesbourne, UK for cv. 'Senshyu Semi-globe Yellow' (from Brewster, 1997b).
