Within 18 perennial and annualAnthemideae species from 7 genera nuclear volume, DNA content and karyogram length are positively correlated. Annuals develop much more rapidly than related perennials. This is obviously due to greater cell elongation and abbreviated cell cycles. Annuals have lower or much higher DNA content and usually more heterchromatin than related perennials. Possible direct influences of nuclear on developmental parameters, and different evolutionary strategies in annuals and perennials are discussed.
