Post-production Fertilization Research
fertilizer rates, particularly high levels of nitrogen, decrease postharvest
longevity and increase bud drop in crops such as potted roses and
mums (Nielsen and Starkey, 1999; Ter Hell and Hendriks, 1995). Because
plant demand for nutrients decreases at flowering, supplying unneeded
nutrients results in a build-up of soluble salts. These higher soluble
salt levels cause root injury, reducing the plants' ability to absorb
water and nutrients (Nell et al., 1989).
